We analyze the safety question for the Non-Monotonic Transform NMT model, an access control model that encompasses a wide variety of practical access control mechanisms. In genera...
Designers of cryptographic systems are at a disadvantage to most other engineers, in that information on how their systems fail is hard to get: their major users have traditionall...
Many recent research e orts in computer security focus on constructing provably secure authentication protocols. Although many of the resulting protocols rely on the a priori secu...
This paper describes an access control mechanism that enforces at the network level an access control decision that is taken at the application level. The mechanism is based on th...
This paper presents a new approach to precompute all odd points [3]P, [5]P, . . . , [2k - 1]P, k 2 on an elliptic curve over Fp. Those points are required for the efficient evalua...
