New Constructions on Broadcast Encryption and Key Pre-distribution Scheme

[[abstract]]This talk is about constructing various new techniques on secure group communication schemes. We present a new broadcast encryption scheme RBE: being particularly efficient in multiple revocation, and a node-based key pre-distribution scheme, it remedies the key overlapping problem of pool-based schemes. Starting with a detailed analysis on broadcast encryption and group key distribution schemes, we discuss the influence of "join" as well as the feasibility of supporting it in broadcast encryption schemes by means of performing full updating or overprovisioning.[[fileno]]2030167030016[[department]]電機工程學
