General Composition and Universal Composability in Secure Multi-Party Computation
Concurrent general composition relates to a setting where a secure protocol is run in a network concurrently with other, arbitrary protocols. Clearly, security in such a setting i...

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 Security with Global Setup
Abstract. Cryptographic protocols are often designed and analyzed under some trusted set-up assumptions, namely in settings where the participants have access to global information...

Adaptively Secure Feldman VSS and Applications to Universally-Composable Threshold Cryptography
We propose the first distributed discrete-log key generation (DLKG) protocol from scratch which is adaptively-secure in the non-erasure model, and at the same time completely avoi...
