Abstract. We examine the IND-qCPA security of the wide-spread block cipher modes of operation CBC, CFB, OFB, CTR, and XTS (i.e., security against quantum adversaries doing queries ...
The paper describes improved analysis techniques for basis reduction that allow one to prove strong complexity bounds and reduced basis guarantees for traditional reduction algorit...
Functional encryption is a new public key paradigm that solves, in a non-interactive way, most of the security challenges raised by cloud computing. A recent paper by Abdalla, Bou...

Abstract. Group signatures are an important privacy-enhancing tool which allow members of a group to anonymously produce signatures on behalf of the group. Ideally, group signature...
Abstract. While threshold signature schemes have been presented before, there has never been an optimal threshold signature algorithm for DSA. Due to the properties of DSA, it is f...
