Performance Analysis of Various Secret Sharing Techniques

Surbhi Sharma, Pradeep Kumar

Abstract: Various secret sharing schemes have been developed since Shamir proposed secret sharing scheme in 1979 for the application of key distribution. A secret sharing scheme allows a dealer to protect a secret among a set of participants with each participant holding one share. A study is done on multiple secret sharing schemes based on matrix projection and secret sharing scheme for implicit data security. In secret sharing scheme based on matrix projection, secrets are organized in form of square matrix. Data pieces are said to be implicitly secure if no explicit encryption key is used and pieces in themselves do not reveal any information until at least certain number of them brought together. In this paper we analyze both types of secret sharing schemes and at last a secret scheme based on visual cryptography is also discussed.
