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 we introduce a novel technique for transforming any
"stand-alone" secure protocol (i.e., one whose security is only guaranteed if
executed in isolation) into one that is secure under concurrent executions.
Contrary to previous results in the literature, this result is established
without relying on additional trusted infrastructure or cryptographic hardness
assumption
