Some (k, n)-threshold image secret sharing schemes encrypt the secret image into n noise-like shadow images with size 1/k times that of the original secret image. The small size o...

We study proactive two-party signature schemes in the context of user authentication. A proactive two-party signature scheme (P2SS) allows two parties—the client and the serverâ...
