`
`On more of the research front (but largely integral to the business needs),
`worked on a scalable design and system for trusted third-party revocation
`services. The theory and system enables countless numbers of clients to
`subscribe to freshness evidence concerning the validity of credentials (e.g.,
`the validity of identity and attributed certificates). Also, worked on “Delaying
`Functions” which are functions that take a provably long time to compute and
`preserve randomness on the inputs. Delaying functions are important since
`they can minimize the need to trust a third party (e.g., we eliminate trust in a
`lottery agent to pick a random number to determine a lottery winner). Worked
`on methods to check the validity of information returned from a stack and
`queue stored on a hostile environment. Our method improves on the
`efficiency over other known methods. Worked on protocols for Unlinkable
`Serial Transactions. These protocols prevent a networked service from
`tracking the behavior of its customers on a per transaction basis. Previously,
`granularity of protection was at the level of protecting the identity of
`customers (e.g., using pseudonyms). Show the service vendor can be
`protected from abuse due to simultaneous or ``cloned’’ usage from a single
`subscription (e.g., password sharing). Worked on methods to check properties
`of code without requiring software vendors to releasing code to trusted third
`parties. The approach assumes content providers are provided with physically
`secure computing devices. Also, worked on techniques for using trusted
`software certification authorities to secure software-module configuration
`management. Worked on techniques for automatically detecting known and
`chosen plaintext pairs in cryptographic protocols. Discovered new (but
`related) attacks on IPSEC protocols.

`
`independence of trusted paths established through trusted intermediaries.
`Formalize the problems of locating maximum sets of paths using
`independence properties in a graph-theoretic framework, gave evidence
`that they are not polynomial-time solvable, and proposed approximation
`algorithms for these problems. Introduce PathServer, a service for finding
`sets of such paths to support authentication in PGP-based applications.
`Worked on acceptable metrics for authentication. This work gives a set
`of guiding principles for the design of authentication metrics, illustrates
`our principles by demonstrating the limitations of previous approaches,
`and defines a new metric. The new metric establishes the amount for
`which a transaction may be insured. It is computed as the min-cut of a
`trust graph where the labels of the graph represent insurance amounts.
`Worked on an analysis method to reason about synchronization, recency,
`and revocation in distributed systems. The approach helps designers
`learn hidden assumptions necessary to establish recent-secure
`authentication. Recent-secure authentication requires that all assumptions
`necessary for the transaction satisfy designated freshness policies.
`Worked on public-key methods for establishing trusted third-party
`revocation services. The technique adds recentness verification policies
`to identification/ authorization/ delegation/ policy certificates. By
`adjusting freshness constraints, the delay for certain revocation can be
`arbitrarily bounded. Using this technique, design a general architecture
`for a secure and highly available trusted-third party revocation service.
`This service enables a trusted-third party to be a revocation authority
`(e.g., authority for issuing revocation statements) while the customer
`retains authority on issuing it's own identification/ authorization/
`delegation certificates. The practical significance of this theory is that the
`customer can delegate revocation authority (i.e., the difficult task of
`making revocation lists highly available and fresh) to a less trusted
`principal. Gave a general method for formally specifying and reasoning
`about revocation in distributed systems with any desired degree of
`immediacy for revoking authentication.
