Moreover, we give two concrete constructions of stag-CCA-secure threshold tag-based encryption schemes, under the decisional bilinear Diffie-Hellman assum

Peter L. Harrod,Derek C. Barkerng it possible for any malicious verifier to transfer the proof to anyone else. It is for instance the case for e-passports where the signature from the national authority authenticates personal data. To solve this problem, we can prove knowledge of a valid signature without revealing it. This proof

Peter L. Harrod,Derek C. Barker of data cannot be checked using traditional MACs and checksums. In addition, network coded systems are vulnerable to pollution attacks where a single malicious node can flood the network with bad packets and prevent the receiver from decoding the packets correctly. Signature schemes have been propo
