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...
Abstract. This paper describes a new method in pairing-based signature schemes for identifying the invalid digital signatures in a batch after batch verification has failed. The me...
The strongest standard security notion for digital signature schemes is unforgeability under chosen message attacks. In practice, however, this notion can be insufficient due to ...
