Abstract. To be accepted, a cryptographic scheme must come with a proof that it satisfies some standard security properties. However, because cryptographic schemes are based on no...
Reducing the minimum assumptions needed to construct various cryptographic primitives is an important and interesting task in theoretical cryptography. Oblivious Transfer, one of ...
We investigate some of the algebraic properties of the SAFER block cipher when the message space is considered as a Z-module. In particular we consider the invariant Z-submodules ...
Abstract. Cryptographic transactions form the basis of many common security systems found throughout computer networks. Supporting these transactions with biometrics is very desira...
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...
