`
`
`
`Engagement
`1.
`I have been retained by Petitioners Sony Mobile Communications AB,
`
`I.
`
`Sony Mobile Communications, Inc., Sony Electronics Inc., and Sony Corporation
`
`(collectively, “Sony” or “Petitioners”) to provide this declaration concerning the
`
`technical subject matter relevant to a petition for inter partes review of U.S. Patent
`
`No. 6,411,941 (“’941 patent”).
`
`2.
`
`Specifically, I was asked to review the declaration of Dr. Andrew
`
`Wolfe that was submitted by the petitioners in IPR2020-01609 as Exhibit 1003 and
`
`form an opinion of whether I agreed with the facts, analysis, and conclusions in
`
`that declaration.
`
`II. Background and Qualifications
`3.
`I am a Professor in the Computer Science Department at Stony Brook
`
`University (part of the State University of New York (“SUNY”) system). I direct
`
`the File-systems and Storage Lab (FSL) at Stony Brook’s Computer Science
`
`Department. My research interests include file systems and storage systems,
`
`operating systems, information technology and system administration, security and
`
`information assurance, networking and distributed systems, energy efficiency,
`
`performance and benchmarking, compilers, applied machine learning, and software
`
`engineering.

`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
` I studied at a professional high school in Israel, focusing on electrical
`
`4.
`
`engineering (“EE”), and graduated in 1982. I spent one more year at the high
`
`school’s college division, receiving a special Certified Technician’s degree in EE.
`
`During that time, I used and programmed PROM, EPROM, and EEPROM devices.
`
`I then went on to serve in the Israeli Defense Forces for three years (1983–1986). I
`
`received my Bachelor of Science degree in computer science (“CS”) in 1991, my
`
`Master’s degree in CS in 1994, and my Ph.D. in CS in 2001—all from Columbia
`
`University in New York.
`
`5. When I began my undergraduate studies at Columbia University, I
`
`also started working as a student assistant in the various campus-wide computer
`
`labs, eventually becoming an assistant to the head labs manager, who was
`
`managing all public computer labs on campus. During that time, I also became
`
`more involved with research within the CS Department at Columbia University,
`
`conducting research on operating systems, file and storage systems, security, and
`
`other topics. I also assisted the CS department’s computer administrators in
`
`managing the department’s computers, which included storage, IT, networking,
`
`and cyber-security related duties.
`
`6.
`
`During the late 1980s, I became exposed to and aware of information
`
`assurance topics. As the then-fledgling Internet was growing in popularity, so were
`
`security problems and cyber-attacks of various sorts. For example, I was an
`
`3
`
`Sony Ex. 1015
`
`Page 3 of 81
`
`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
`
`undergraduate student working on computer programming assignments when the
`
`infamous “Morris Worm” hit the Internet in November of 1988.
`
`7.
`
`In 1991, I joined Columbia University’s CS department as a full-time
`
`systems administrator, studying towards my MS degree part-time. My MS thesis
`
`topic related to file system reliability, fault tolerance, replication, and failover in
`
`mobile networked systems. My main duties as a systems administrator involved
`
`installing, configuring, and managing many networked servers, proxies, and
`
`desktops running several operating systems, as well as network devices setup; this
`
`included many hardware upgrades, device upgrades, and BIOS firmware/chipset
`
`updates/upgrades. My duties also included ensuring reliable, secure, authenticated
`
`access to networked systems and licensed software, as well as software updates,
`
`security, and bug fixes. Examples of servers and their protocols included email
`
`(SMTP), file transfer (FTP), domain names (DNS), network file systems (NFS),
`
`network news systems (NNTP), and Web (HTTP).
`
`8.
`
`In 1994, I left my systems administrator position to pursue my
`
`doctoral studies at Columbia University. My Ph.D. thesis topic was on versatile file
`
`system development, with examples in the fields of security and encryption,
`
`efficiency, reliability, and failover. I continued to work part-time as a systems
`
`administrator at the CS department, and eventually I was asked to serve as
`
`manager to the entire information technology (“IT”) staff. From 1991 to 2001, I
`
`4
`
`Sony Ex. 1015
`
`Page 4 of 81
`
`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
`
`was a member of the faculty-level Facilities Committee that oversaw all IT
`
`operations at the CS department. During this entire time, topics of information
`
`assurance and software protection became more prominent and time-consuming in
`
`the lives of system administrators worldwide, and my work at Columbia was no
`
`different. For example, configuring/maintaining firewalls and proxies and applying
`
`security patches, and [re]licensing software, became more important and a
`
`dominant part of everyday IT duties, as well as defending against a growing list of
`
`copyright violations and malicious software threats (e.g., viruses, worms, Trojans,
`
`spyware, and more).
`
`9.
`
`As part of my Ph.D. studies at Columbia, I collaborated on projects to
`
`develop advanced AI-like techniques to detect previously unknown viruses (a.k.a.
`
`“zero-day malware”), using data mining and rule-based detection. This work led to
`
`several highly cited papers (nearly 1,300 citations for one of the papers alone), and
`
`two patents. I also became a Teaching Assistant (TA) for a first-ever Computer
`
`Security course given at Columbia University’s CS department with Dr. Matt
`
`Blaze as instructor.
`
`10. From 1990 to 1998, I consulted for SOS Corporation and HydraWEB
`
`Technologies, as a systems administrator and programmer, managing data storage
`
`use and backup/restore duties, as well as information assurance and cyber-security
`
`(e.g., malware protection, software licensing). From 1994 to 2000, I led projects at
`
`5
`
`Sony Ex. 1015
`
`Page 5 of 81
`
`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
`
`HydraWEB Technologies, and then became the Director of Software
`
`Development—overseeing the development of several products and appliances
`
`such as stateful firewalls and HTTP load-balancers. I helped design and implement
`
`HydraWEB’s licensing method which used an encrypted, hashed content including
`
`information unique to the licensed software (e.g., serial numbers, MAC addresses).
`
`Since 2009, I have consulted for Packet General Networks, a startup specializing in
`
`secure storage and applications’ data security in the cloud.
`
`11.
`
`In 2001, I joined the faculty of Stony Brook University, a position I
`
`have held since. In 2002, I joined the Operations Committee, which oversees the
`
`IT operations of the CS department at Stony Brook University. From 2006 to 2010,
`
`I was the Director of IT Operations of the CS department; my day-to-day duties
`
`included setting policies regarding computing, hiring and training new staff,
`
`assisting any staff with topics of my specialty, defining requirements for new
`
`software/hardware, and purchasing. From 2010 to 2015, I have served as the Co-
`
`Chair to the Operations Committee. From 2016 to 2019, I oversaw the IT
`
`Operations as the Chair of the Operations Committee. A significant component of
`
`these duties included defining and helping implement policies for access control,
`
`firewalling, software licensing, anti-malware, anti-denial-of-service, and intrusion
`
`prevention—so as to ensure the security of users and their data, while minimizing
`
`the inconvenience and performance impact to users. These duties include

`
`

`

`
`
`
`protecting users from external threats as well as protecting the outside world from
`
`inside threats (e.g., infected laptops that start to spam outsiders or steal and
`
`transmit sensitive information). Since late 2019, I’ve been a member of the
`
`department’s Executive Committee that also oversees all IT operations.
`
`12. As of 2021, I am co-chairing a Stony Brook University wide working
`
`group to consolidate and streamline numerous IT software systems securely across
`
`the many disparate campus units.
`
`13.
`
`In 2017, I became the department’s Graduate Academic Adviser,
`
`advising all Masters students (over 400 on average annually) and many other
`
`graduate students on an assortment of academic matters.
`
`14. Since 2001, I personally configured and managed my own research
`
`lab’s network. This includes setting up and configuring a bi-directional Linux
`
`based stateful packet firewall, Web proxies, SSL-based services (secure HTTP,
`
`email, etc.), and Denial-of-Service prevention techniques. I’ve personally installed,
`
`configured, licensed, changed, replaced parts, and upgraded components in
`
`numerous devices from handhelds to laptops to servers.
`
`15. Throughout the 1990s and at least until 2004, I continued to
`
`personally use, install, configure, and train others on anti-malware software to
`
`protect users from viruses, Trojans, worms, spyware, and more. I’ve personally
`
`used software from Norton, Symantec, Trend Micro, McAfee, and others. I’ve
`

`
`

`

`
`
`
`used this software on Microsoft Windows, Linux systems, and on Apple Mac OS
`
`X systems.
`
`16. Since 1995, I have taught courses on operating systems, storage and
`
`file systems, advanced systems programming in Unix/C, systems administration,
`
`data structures, data/software security, and more. My courses often use storage, file
`
`systems, distributed systems, and system/network security as key teaching
`
`principles and practical examples for assignments and projects. I have taught these
`
`concepts and techniques to my students, both to my direct advisees as well as in
`
`my courses. For example, in my graduate Operating Systems course, I often cover
`
`Linux’s kernel mechanisms to protect users, applications, and data files. And in the
`
`System Administration undergraduate course, I covered many topics such as
`
`networking, firewalling, and cyber-security—including configuring and
`
`maintaining site security policies, DDoS handling, and the impact on anti-malware
`
`scanners on system performance.
`
`17. My research often investigates computer systems from many angles:
`
`security, efficiency, energy use, scalability, reliability, portability, survivability,
`
`usability, ease-of-use, versatility, flexibility, and more. My research gives special
`
`attention to balancing five often-conflicting aspects of computer systems:
`
`performance, reliability, energy use, security, and ease-of-use. Since joining Stony
`
`Brook University in 2001, my group in the File-systems and Storage Lab (FSL)
`
`8
`
`Sony Ex. 1015
`
`Page 8 of 81
`
`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
`
`has developed many file systems and operating system extensions; examples
`
`include a highly-secure cryptographic file system, a portable copy-on-write (COW)
`
`versioning file system, a tracing file system useful to detect intrusions, a replaying
`
`file system useful for forensics, a snapshotting and sandboxing file system, a
`
`namespace unification file system (that uses stackable, file-based COW), an anti-
`
`virus file system, an integrity-checking file system, a load balancing and
`
`replication/mirroring file system, network file system extensions for security,
`
`distributed secure cloud-based storage systems, a compiler to convert user-level C
`
`code to in-kernel efficient yet safe code, GCC plugins, stackable file system
`
`templates, and a Web-based backup system. I continue to maintain and release
`
`newer versions of some of these file systems and software.
`
`18.
`
`I have published over 120 refereed publications (in ACM, IEEE,
`
`USENIX, and more). To date, my publications have been cited more than 8,500
`
`times (as per Google Scholar as of March 15, 2021). My papers cover a wide range
`
`of related technologies such as file systems, storage systems, security, performance
`
`benchmarking and optimization, energy efficiency, system administration, and
`
`more. I also published a book titled “Linux NFS and Automounter Administration”
`
`(Sybex, 2001), covering systems administration topics related to network storage
`
`and data security.
`
`9
`
`Sony Ex. 1015
`
`Page 9 of 81
`
`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
`
`19. Some of my research has led to public software releases that have
`
`been used worldwide. I have publicly maintained the Amd Berkeley Automounter
`
`in a package called “am-utils” since 1992; this software helps administrators
`
`manage the multitude of file system mounts on dozens of different Unix systems.
`
`Since 1997, I have maintained and released several stackable file system software
`
`projects for Linux, FreeBSD, and/or Solaris, in a package called FiST. One of my
`
`stackable file system encryption projects, called Cryptfs, became the basis for
`
`IBM’s public release of eCryptfs, now part of Linux. Packet General Networks, for
`
`whom I have provided consulting services since 2009, licensed another encryption
`
`file system called Ncryptfs. Another popular file system released in 2003, called
`
`Unionfs, offers namespace unification, transparent shadow copying (a.k.a. copy-
`
`on-write or COW), file system snapshotting (e.g., useful for forensics), and the
`
`ability to save disk space by sharing a read-only copy of data among several
`
`computers, among other features.
`
`20. My research and teaching make extensive use of security features. For
`
`example, each time I taught the graduate operating system course, the first
`
`homework assignment includes the creation of a new system call that performs
`
`new or added functionality, often for encrypting a file or verifying its integrity;
`
`many of my other assignments cover topics of user/process access control, anti-
`
`virus filtering, and more. Since 2001, over 1,000 graduate students were exposed
`
`10
`
`Sony Ex. 1015
`
`Page 10 of 81
`
`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
`
`to these simple principles directly through my teaching and research at Stony
`
`Brook University.
`
`21.
`
`In another, undergraduate course titled “Advanced Systems
`
`Programming in Unix/C,” I cover many topics of system security and
`
`vulnerabilities, such as the structure of UNIX processes, memory segments such as
`
`the heap and stack, and an assortment of tools and techniques to prevent bugs from
`
`being exploited by malware. Often, the first assignment for this course is to
`
`develop a tool to encrypt/decrypt files using advanced ciphers, and use digital
`
`signatures to certify the cipher keys used. Since 2001, several hundred
`
`undergraduate students were exposed to these principles directly through my
`
`teaching and research at Stony Brook University.
`
`22.
`
`In yet another undergraduate course, System Administration, I taught
`
`network configuration, firewall security, and system security.
`
`23. My research has been supported by many federal and state grants as
`
`well as industry awards, including an NSF CAREER award, two IBM Faculty
`
`awards, two NetApp Faculty awards, a Western Digital award, several Dell-EMC
`
`awards, and several equipment gifts. I was the winner of the 2004 Computer
`
`Science Department bi-annual Graduate Teaching Award, the winner of the 2006
`
`Computer Science Department bi-annual Research Excellence Award, and a
`
`11

`
`

`

`Zadok Declaration for Petition for Inter Partes Review of U.S. Pat. No. 6,411,941
`
`
`
`recipient of the 2008 SUNY Chancellor’s Excellence in Teaching award (an award
`
`that can be given only once a lifetime).
`
`24. My service record to the community includes being the co-chair for
`
`the USENIX Annual Technical Conference in 2020 (ATC’20); co-chairing
`
`USENIX File and Storage Technologies (FAST) in 2015 and participating in the
`
`FAST Steering Committee since 2015; co-chairing in 2012 and participating in the
`
`Steering Committee of the ACM SYSTOR conference; and participating in the
`
`Steering Committee of the Workshop on Hot Topics in Storage and File Systems
`
`(HotStorage) since 2021. Additionally, I have also been an Associate Editor to the
`
`ACM Transactions on Storage (TOS) journal since 2009.
`
`25.
`
`I am a named inventor on four patents, two titled “Systems and
`
`Methods for Detection of New Malicious Executables” (U.S. Patent No. 7,979,907,
`
`issued July 12, 2011; and U.S. Patent No. 7,487,544, issued February 3, 2009); and
`
`two more titled “Multi-Tier Caching,” (U.S. Patent No. 9,355,109, issued May 31,
`
`2016; and U.S. Patent 9,959,279, issued May 1, 2018).
`
`26.
`
`I have been disclosed as a testifying expert in twelve cases (including
`
`IPRs) in the past four years. I have been deposed 11 times and testified in trial
`
`twice.
`
`27. A complete copy of my curriculum vitae, which includes a list of my
`
`publications and contains further details on my education, experience, publications,

`
`28. The compensation I receive through my consulting company, Zadoks
`
`Consulting, LLC, is $450 per hour for my time, plus out-of-pocket expenses. This
`
`compensation is not dependent in any way on the contents of this Declaration, the
`
`substance of any testimony I may provide, or the outcome of this proceeding.
`
`III.
`
`Information Considered
`29.
`In drafting this declaration and forming the opinions therein, I relied
`
`on my years of education, research, and industry and academic experience. I also
`
`relied on the materials listed in Appendix B.
`

`
`claim terms in the asserted claims of the ’941 Patent.
`
`
`
`I declare all statements made herein of my own knowledge are true and that
`
`all statements made on information and belief are believed to be true; and further
`
`that the statements were made with the knowledge that willful false statements and
`
`the like so made are punishable by fine or imprisonment, or both, under Section 1001
`
`of Title 18 of the United States Code.
