Practical UC security with a Global Random Oracle
Efficient Secure 2PC UC-security Global Random Oracle
2016/1/6
We show that there exist commitment, zero-knowledge and general function evaluation protocols with universally composable security, in a model where all parties and all protocols have access to a sing...
On the (Non-) Equivalence of UC Security Notions

2012/3/27
In this work we investigate the relations among various security notions and show their connection with the game-theoretic notion of strong universal implementation. More precisely, we present a separ...

2011/7/25
In this work we investigate the relations among various security notions. More precisely, we present a separation result between two variants of UC security defi nition: 1-bit specialized simulator UC...
Equivocal Blind Signatures and Adaptive UC-Security
Equivocal Blind Signatures Adaptive UC-Security
2008/9/4
We study the design of practical blind signatures in the universal composability (UC) setting against adaptive adversaries. We introduce a new property for blind signature schemes that is fundamental ...
