A PERVASIVE SECRET SHARING SCHEME FOR EMBEDDED VISUAL COMMUNICATION SYSTEM

摘要

A simple secret sharing scheme for secure visual communications is presented in this paper. Secret sharing schemes allow a group of participants at different locations to share a secret (i.e., an image) among them by splitting it into n pieces ("shares" or "shadows"). In case of the (k, n) secret sharing scheme only a group of k qualified participants among n (where k ≤ n) can reconstruct the secret. This paper presents an (n, n) secret sharing scheme. This scheme randomizes one share after another by executing XOR operations with random seeds derived from an initial seed. This scheme can also be used as an image encryption scheme. This scheme is resistant to collusion attacks.
