A cryptanalysis is given of a MAC proposal presented at CRYPTO 2003 by Cary and Venkatesan. A nice feature of the CaryVenkatesan MAC is that a lower bound on its security can be pr...
We consider the problem of implementing a security protocol in such a manner that secrecy of sensitive data is not jeopardized. Implementation is assumed to take place in the cont...
Abstract. Recently, methods from provable security, that had been developped for the last twenty years within the research community, have been extensively used to support emerging...
An e cient implementations of the main building block in the RSA cryptographic scheme is achieved by mapping a bit-level systolic array for modular exponentiation onto Xilinx FPGAs...
This paper suggests a new building block for cryptographic protocols and gives two instantiations of it. The concept is to generate two descriptions of the same group: a public des...
