Reputation management and signature delegation: A distributed approach

In this paper, we present a novel protocol, called Distributed Signcryption with Verifiable Partial Signature (DiSigncryption) protocol, to allow an agent owner to securely distribute his signing capability among a set of trusted third party hosts (TTPhosts) via a mobile agent. The protocol incorporates three schemes: a novel Distributed Reputation Management scheme, a modified version of the Distributed Signcryption method proposed in [23], and an extended version of the Agent-based Threshold Proxy Signcryption (ATPS) protocol proposed in [2]. The security properties of the proposed protocol are analyzed, and the protocol is compared with the most related work. Keywords Proxy signature . Signature delegation .
