— Voice over IP (VoIP) services based on the Session Initiation Protocol (SIP) gain ground as compared to other protocols like MGCP or H.323. However, the open SIP architecture c...
—The interaction between MAC protocols and interference in wireless multi-hop networks introduces extra constraints on achievable flow rates. In this paper, we formulate an optim...
The combination of first-order epistemic logic and formal cryptography offers a potentially very powerful framework for security protocol verification. In this article, we addre...
Can we secure user authentication against eavesdropping adversaries, relying on human cognitive functions alone, unassisted by any external computational device? To accomplish thi...
Every novel cooperative arrangement of mutually suspicious parties interacting electronically -- every smart contract -- effectively requires a new cryptographic protocol. However,...
