Security of (n, n)-threshold audio secret sharing schemes encrypting audio secrets
Yuto Miura, Yodai Watanabe · 2016
Secret sharing is a method of encrypting a secret into multiple pieces called shares so that only qualified sets of shares can be employed to reconstruct the secret. Audio secret sharing (ASS) is an example of secret sharing whose decryption can be performed by human ears. This paper examines the security of (n, n)-threshold ASS schemes encrypting audio secrets by estimating the mutual information between secret and shares.
