We present a new primitive—Append-only Signatures (AOS)—with the property that any party given an AOS signature Sig[M1] on message M1 can compute Sig[M1 M2] for any message M2...

Abstract. A feasible solution to prevent potential misuse of signatures is to put some restrictions on their verification. Therefore S.J.Kim, S.J.Park and D.H.Won introduced the n...
Peer-to-Peer (p2p), as an emerging technology, is exerting huge influence on various application scenarios. Meanwhile, agents, assisting applications in traditional paradigm with...
To be practical, systems for ensuring secure information flow must be as permissive as possible. To this end, the author recently proposed a type system for multi-threaded progra...
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 ...
