The Optimal Linear Secret Sharing Scheme for Any Given Access Structure
cryptographic protocols
2012/3/29
Any linear code can be used to construct a linear secret sharing scheme. In this paper, it is shown how to decide optimal linear codes (i.e., with the biggest information rate) realizing a given acces...

Ciphertext-Policy Attribute-Based Encryption(CP-ABE) is a system for realizing complex access control on encrypted data, in which attributes are used to describe a user's credentials and a party encry...
Multi-Party Computation from any Linear Secret Sharing Scheme Secure against Adaptive Adversary: The Zero-Error Case
Multi-Party Computation Linear Secret Sharing Scheme Secure Zero-Error Case
2009/4/7
We use a general treatment of both information-theoretic and cryptographic settings for
Multi-Party Computation (MPC), based on the underlying linear secret sharing scheme. Our
goal is to study theM...
