Secret Sharing Scheme Suitable for Cloud Computing

DOI

説明

Secret sharing schemes have recently been considered to apply for cloud computing in which many users distribute multiple data to servers. However, when Shamir's (k, n) secret sharing is applied to cloud systems, the amount of share increases more than n times the amount of the secret. Therefore, in this paper we propose a new secret sharing scheme that can reduce the amount of share different from Ramp type secret sharing, suitable for cloud systems, and we prove that it is computationally secure.
