Digital signatures and message authentication codes are well known methods for ensuring message integrity. However, they rely on computations which are too hard to be performed by ...
We analyse the security of new hash functions whose compression function is explicitly defined as a sequence of multivariate equations. First we prove non-universality of certain ...
This paper presents a new model for controlling information flow in systems with mutual distrust and decentralized authority. The model allows users to share information with dis...
We can view an existing Message Authentication Code (MAC) as a Carter-Wegman MAC in spite of the fact it may not have been designed as one. This will make the analysis easier than...
We introduce a type system based on intervals, objects representing the time in which a block of code will execute. The type system can verify time-based properties such as when a...
