System design often explores optimality of performance. What is optimal is, however, often not predefined or static in most cases, because it is affected by the context of operat...
Symbolic execution can be problematic when applied to real applications. This paper addresses two of these problems: (1) the constraints generated during symbolic execution may be ...
We describe a new algorithm for analysing security protocols that use XOR, such as key-management APIs. As a case study, we consider the IBM 4758 CCA API, which is widely used in t...
We consider the following problem in a stream model: Given a sequence a = a1, a2, . . . , am wich each ai ∈ [n] = {1, . . . , n} and m > n, find a duplicate in the sequence, ...
We investigate the discrete (finite) case of the Popper-Renyi theory of conditional probability, introducing discrete conditional probabilistic models for (multi-agent) knowledge...
