Verifying Secrets and Relative Secrecy
Systems that authenticate a user based on a shared secret (such as a password or PIN) normally allow anyone to query whether the secret is a given value. For example, an ATM machi...

On the bound for anonymous secret sharing schemes
In anonymous secret sharing schemes, the secret can be reconstructed without knowledge of which participants hold which shares. In this paper, we derive a tighter lower bound on t...

Algebraic Geometric Secret Sharing Schemes and Secure Multi-Party Computations over Small Fields
Abstract. We introduce algebraic geometric techniques in secret sharing and in secure multi-party computation (MPC) in particular. The main result is a linear secret sharing scheme...
