—Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption simultaneously, at a cost significantly lower than th...
We construct the first homomorphic signature scheme that is capable of evaluating multivariate polynomials on signed data. Given the public key and a signed data set, there is an...
Mobile Location-Based Services (LBS) have raised privacy concerns amongst mobile phone users who may need to supply their identity and location information to untrustworthy third ...

At TCC 2005, Backes and Cachin proposed a new and very strong notion of security for public key steganography: secrecy against adaptive chosen covertext attack (SS-CCA); and posed ...
We present the first group signature scheme with provable security and signature size O(λ) bits where the group manager, the group members, and the Open Authority (OA) are all id...
