Let ψ be a 2-DNF formula on boolean variables x1, . . . , xn ∈ {0, 1}. We present a homomorphic public key encryption scheme that allows the public evaluation of ψ given an en...
Chameleon signatures are non-interactive signatures based on a hash-and-sign paradigm, and similar in efficiency to regular signatures. The distinguishing characteristic of chamel...
This paper describes a hardware architecture for modular multiplication operation which is efficient for bit-lengths suitable for both commonly used types of Public Key Cryptogra...
Digital signatures, like physical signatures, can verify that a specific user affixed their signature to a document and they can also verify that the document is the same as when ...
Firewalls typically filter network traffic at several different layers. At application layer, filtering is based on various security relevant information encapsulated into proto...
