A Unified Framework for Concurrent Security
Cryptographic protocols have been developed for a variety of tasks, including electronic auctions, electronic voting systems, privacy preserving data mining and more. The Internet allows for the concurrent execution of cryptographic protocols. Such concurrency severely challenges their security.

In this talk, I will introduce a unified framework for implementing cryptographic tasks that are secure under concurrent executions. Essentially all results on concurrently secure protocols are obtained as special cases of our framework. This not only leads to conceptually simpler and more efficient solutions, but also allows us to minimize the reliance on trusted infrastructure.
