We introduce Ad Hoc Anonymous Identification schemes, a new multi-user cryptographic primitive that allows participants from a user population to form ad hoc groups, and then prove...

The goal of incremental cryptography is to design cryptographic algorithms with the property that having applied the algorithm to a document, it is possible to quickly update the ...
We propose a new cryptographic primitive called oblivious signaturebased envelope (OSBE). Informally, an OSBE scheme enables a sender to send an envelope (encrypted message) to a ...
The assumption of the availability of tamper-proof hardware tokens has been used extensively in the design of cryptographic primitives. For example, Katz (Eurocrypt 2007) suggests ...
