Abstract. Software agent technology has attracted much attention for developing various distributed systems, composed of autonomous agents interacting with one another using partic...
— Security is paramount in Mobile Ad-hoc Networks (MANET) as they are not conducive to centralized trusted authorities. Several solutions have been proposed MANET in the areas of...
Considering the solution of dynamic access problems in a user hierarchy, a novel scheme based on one-way hash function is proposed to manage the cryptographic keys in the paper. T...
Most of the current security architectures for grid systems use conventional public key infrastructure (PKI) to authenticate grid members and to secure resource allocation to thes...
Abstract. We present a new model that provides clear and precise semantics for authorization. The semantics is independent from underling security mechanisms and is separate from i...
