Authentication of digital documents is an important concern as digital documents are replacing the traditional paper-based documents for official and legal purposes. This is espec...
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 pervasive distribution of digital images triggers an emergent need of authenticating degraded images by lossy compression and transmission. This paper proposes a robust cont...
For the two last decades, electronic authentication has been an important topic. The first applications were digital signatures to mimic handwritten signatures for digital document...
A multisignature scheme for specified group of verifiers needs a group of signers' cooperation to sign a message to a specified group of verifiers that must cooperate to check...
