By functionally decomposing a specific algorithm (the hierarchical secure aggregation algorithm of Chan et al. [3] and Frikken et al. [7]), we uncover a useful general functionali...
A nominative signature scheme allows a nominator (or signer) and a nominee (or verifier) to jointly generate and publish a signature in such a way that only the nominee can verify...
The standard digital signature scheme can be easily subject to key exposure problem In order to overcome this problem; a feasible and effective approach is employed by key-evolving...
