Anonymity is one of the main concerns in group-oriented cryptography. However, most efforts, for instance, group signatures and ring signatures, are only made to provide anonymity ...
We describe and analyze a new digital signature scheme. The new scheme is quite efficient, does not require the the signer to maintain any state, and can be proven secure against ...
In a traditional signature scheme, a signature on a message m is issued under a public key PK, and can be interpreted as follows: "The owner of the public key PK and its corr...
