When the safety community designs their systems to also maintain security properties, it is likely that public-key encryption will be among the tools that are applied. The security...
Abstract. The algorithm proposed by Ha and Moon [2] is a countermeasure against power analysis. The Ha-Moon algorithm has two drawbacks in that it requires an inversion and has a r...
In order to provide a general access control methodology for parts of XML documents, we propose combining rolebased access control as found in the Role Graph Model, with a methodo...
We introduce a new computational problem related to the interpolation of group homomorphisms which generalizes many famous cryptographic problems including discrete logarithm, Diļ¬...
Abstract. In this paper, we examine issues related to the construction of identity-based threshold decryption schemes and argue that it is important in practice to design an identi...
