Let G1 be a cyclic multiplicative group of order n. It is known that the Diffie-Hellman problem is random self-reducible in G1 with respect to a fixed generator g if (n) is known....
Nonnegative matrix factorization (NMF) is a versatile model for data clustering. In this paper, we propose several NMF inspired algorithms to solve different data mining problems....
We establish a new worst-case upper bound on the Membership problem: We present a simple algorithm that is able to always achieve Agreement on Views within a single message latenc...
In this paper, we present a secure group key management scheme for hierarchical mobile ad-hoc networks. Our approach aims to improve both scalability and survivability of group ke...
Specific applications like military or public emergency ones require secure group communication in ad hoc environments. The most suitable solution to provide the expected level of...
