Security of audio secret sharing scheme encrypting audio secrets
Kouta Yoshida, Yodai Watanabe · International Conference for Internet Technology and Secured Transactions · 2012
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 proposes the first ASS schemes encrypting audio secrets whose security is rigorously evaluated in terms of the mutual information between secret and shares.
