A universally composable (UC) blind signature functionality requres users to commit to the message to be blindly signed. It is thereby impossible to realize in the plain model. Th...

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-...
