We derive bounds on the expected loss for authentication protocols in channels which are constrained due to noisy
conditions and communication costs. This is motivated by a
numbe...

: Shor's algorithms for the integer factorization and the discrete logarithm problems can be regarded as a negative effect of the quantum mechanism on publickey cryptography. ...

A number of authentication protocols have been proposed recently, where at least some part of the authentication is performed during a phase, lasting $n$ rounds, with no error corr...

We consider message authentication codes for streams where the key becomes known only at the end of the stream. This usually happens in key-exchange protocols like SSL and TLS wher...

We present our further observations on the structure of the AES algorithm relating to the cyclic properties of the functions used in this cipher. We note that the maximal period of...

Hypothesis tests have been used in the past as a tool in a cryptanalytic context. In this paper, we propose to use this paradigm and define a precise and sound statistical framewo...

In this paper, we revisit the security of several message authentication code (MAC) algorithms based on block ciphers, when instantiated with 64-bit block ciphers such as DES. We e...
