A recent theoretical result proposed Sigma, a novel GM protocol that forms views using a singleround of message exchange. Prior GM protocols have required more rounds in the worst...
Abstract. We present a series of protocols for authenticating an individual’s membership in a group without revealing that individual’s identity and without restricting how the...

Sigma, the first single-round group membership (GM) algorithm, was recently introduced and demonstrated to operate consistently with theoretical expectations in a simulated WAN en...
A Group Key Agreement protocol is a process to establish a cryptographic key for a group of participants over an open network. In this paper, we propose a group key agreement(CAGKA...
Protocols that solve agreement problems are essential building blocks for fault tolerant distributed systems. While many protocols have been published, little has been done to ana...
