New notions of security: achieving universal composability without trusted setup
We propose a modification to the framework of Universally Composable (UC) security [3]. Our new notion, involves comparing the protocol executions with an ideal execution involvin...

Universally composable contributory group key exchange
We treat the security of group key exchange (GKE) in the universal composability (UC) framework. Analyzing GKE protocols in the UC framework naturally addresses attacks by maliciou...

A Universally Composable Scheme for Electronic Cash
We propose a scheme for electronic cash based on symmetric primitives. The scheme is secure in the framework for universal composability assuming the existence of a symmetric CCA2-...

Long-Term Security and Universal Composability
Abstract. Algorithmic progress and future technology threaten today’s cryptographic protocols. Long-term secure protocols should not even in future reveal more information to a...

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...
