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

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

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
