Recent technologies have cleared the way for large scale application of electronic
communication. The open and distributed nature of these communications implies that the …

In this paper we consider the problem of securely measuring distance between two nodes in
a wireless sensor network. The problem of measuring distance has fundamental …

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

We report on the detailed verification of a substantial portion of the Kerberos 5 protocol
specification. Because it targeted a deployed protocol rather than an academic abstraction …

We present a computational analysis of basic Kerberos and Kerberos with public-key
authentication (PKINIT) in which we consider authentication and key secrecy properties. Our …

In wireless systems, neighbor discovery (ND) is a fundamental building block: determining
which devices are within direct radio communication is an enabler for networking protocols …

We propose a development method for security protocols based on stepwise refinement.
Our refinement strategy transforms abstract security goals into protocols that are secure …

We propose a development method for security protocols based on stepwise refinement.
Our refinement strategy guides the transformation of abstract security goals into protocols …

We use refinement to systematically develop a family of key establishment protocols using a
theorem prover. Our development spans four levels of abstraction: abstract security …

Secrecy and authenticity properties of protocols are mutually dependent: every
authentication is based on some secrets, and every secret must be authenticated. This …
