On Secure Multi-party Computation in Black-Box Groups
Abstract. We study the natural problem of secure n-party computation (in the passive, computationally unbounded attack model) of the n-product function fG(x1, . . . , xn) = x1 · x...

Universally Composable Multi-party Computation Using Tamper-Proof Hardware
Protocols proven secure within the universal composability (UC) framework satisfy strong and desirable security properties. Unfortunately, it is known that within the “plain” m...

Multiparty Computation from Somewhat Homomorphic Encryption
We propose a general multiparty computation protocol secure against an active adversary corrupting up to n−1 of the n players. The protocol may be used to compute securely arithm...

Concurrent general composition of secure protocols in the timing model
In the setting of secure multiparty computation, a set of parties wish to to jointly compute some function of their input (i.e., they wish to securely carry out some distributed t...
