Protocol Composition Logic (PCL) is a logic for proving security properties of network
protocols that use public and symmetric key cryptography. The logic is designed around a …

The IEEE 802.11 i wireless networking protocol provides mutual authentication between a
network access point and user devices prior to user connectivity. The protocol consists of …

Many authentication and key exchange protocols are built using an accepted set of standard
concepts such as Diffie–Hellman key exchange, nonces to avoid replay, certificates from an …

We methodically expand protocol narrations into terms of a process algebra in order to
specify some of the checks that need to be made in a protocol. We then apply static analysis …

An apparatus and method for establishing a trusted path between a user interface and a
trusted executable, wherein the trusted path includes a hypervisor and a driver shim. The …

We describe a cryptographically sound formal logic for proving protocol security properties
without explicitly reasoning about probability, asymptotic complexity, or the actions of a …

Modular composition of security mechanisms is complicated by the way that one mechanism
may reveal information that interferes with the security of another. We develop methods for …

Computer network security is critical to fraud prevention and accountability. Network
participants are required to observe predefined steps called security protocols, whose proof …

We develop a compositional method for proving cryptographically sound security properties
of key exchange protocols, based on a symbolic logic that is interpreted over conventional …

We show how to combine trust management theories with nonce-based cryptographic
protocols. The strand space framework for protocol analysis is extended by associating …
