On the Security of Yuan et al.'s Undeniable Signature Scheme
Undeniable signatures were proposed to limit the public verification property of ordinary digital signature. In fact, the verification of such signatures cannot be obtained withou...

Nonce Generation For The Digital Signature Standard
Digital Signature Algorithm (DSA) is an underlying algorithm to form a signature in the Digital Signature Standard (DSS). DSA uses a new random number (or nonce) each time a signa...

Certificateless Group Oriented Signature Secure Against Key Replacement Attack
Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificate...

PIXBAS "Pixel Based Offline Signature Verification"
Many systems are available to verify the signatures in bank cheques. In this paper, we verify the offline signatures by taking a boundary of the entire signature and do the pixel ...

On Security Notions for Verifiably Encrypted Signature
First we revisit three - BGLS, MBGLS and GZZ verifiably encrypted signature schemes [2, 3, 6]. We find that they are all not strong unforgeable.We remark that the notion of existen...

Offline Signature Verification Based on Pseudo-Cepstral Coefficients
Features representing information about pressure distribution from a static image of a handwritten signature are analyzed for an offline verification system. From gray-scale image...

Geometric Centroids and their Relative Distances for Off-line Signature Verification
In this paper, we propose a new approach for symbolic representation of off-line signatures based on relative distances between centroids useful for verification. Distances betwee...

A secure unidirectional proxy re-encryption using identity and secret key exchange
Proxy re-encryption, abbreviated as PRE, is a cryptosystem which allows the proxy to re-encrypt a cirphertext without accessing the underlying message. The re-encryption protocol ...

Efficient Confirmer Signatures from the "Signature of a Commitment" Paradigm
Generic constructions of designated confirmer signatures follow one of the following two strategies; either produce a digital signature on the message to be signed, then encrypt th...
