—This paper discusses public-key authenticated key agreement protocols. First, we critically analyze several authenticated key agreement protocols and uncover various theoretical...
Suppose a principal in a cryptographic protocol creates and transmits a message containing a new value v, later receiving v back in a different cryptographic context. It can concl...
Security in browsers is based upon users trusting a set of root Certificate Authorities (called Trust Anchors) which they may know little or nothing about. Browser vendors face a...
We present a general framework for constructing two-message oblivious transfer protocols using a modification of Cramer and Shoup’s notion of smooth projective hashing (2002). ...
Classical distributed protocols like broadcast or multi-party computation provide security as long as the number of malicious players f is bounded by some given threshold t, i.e., ...
