We investigate whether security of multiparty computation in the information-theoretic setting implies their security under concurrent composition. We show that security in the sta...
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...
We show how to securely realize any multi-party functionality in a way that preserves security under an a-priori bounded number of concurrent executions, regardless of the number ...
We present a robust multiparty computation protocol. The protocol is for the cryptographic model with open channels and a polytime adversary, and allows n parties to actively secur...
Abstract. As an extension of multi-party computation (MPC), we propose the concept of secure parallel multi-party computation which is to securely compute multi-functions against a...
