An Improved Proxy Blind Signature Scheme Based on Factoring and ECDLP

2009 International Conference on Computational Intelligence and Software Engineering, 2009
A proxy signature scheme enables a proxy signer to sign messages on behalf of the original signer. A blind signature is the concept with a salient feature that the signer cannot make a linkage between the blind signature and the identity of the requester.

On the Strength Comparison of the ECDLP and the IFP

2012
At present, the RSA cryptosystem is most widely used in public key cryptography. On the other hand, elliptic curve cryptography (ECC) has recently received much attention since smaller ECC key sizes provide the same security level as RSA. Although there are a lot of previous works that analyze the security of ECC and RSA, the comparison of strengths ...

Cryptanalysis and improvement of a ECDLP based proxy blind signature scheme

Journal of Discrete Mathematical Sciences and Cryptography, 2018
The proxy blind signature scheme (PBSS), allows the authorized proxy signer to use his proxy private key to create a legal blind signature on behalf of original signer. Recently, Alghazzawi, Salim and Hasan (A-S-H), presented the elliptic curve cryptography (ECC) based PBSS.

Blind Proxy Signature Scheme Based on Both ECDLP and IFP

2009 International Conference on Management and Service Science, 2009
After studying blind proxy signature scheme and a group of digital signature schemes based on two hard mathematical problems, a new blind proxy signature scheme based on both Elliptic Curve Discrete Logarithm Problem and Integer Factoring Problem is proposed and its security is analyzed. The analysis results show that the scheme satisfies all necessary

Security Analysis of a Proxy Blind Signature Scheme Based on ECDLP

2008 4th International Conference on Wireless Communications, Networking and Mobile Computing, 2008
Proxy blind signature, which combines the properties of both proxy signature and blind signature, is useful in many applications. Based on ECLDP, Wang et al. recently proposed a proxy blind signature scheme. In this paper, we present a security analysis on Wang's scheme and prove it does not possess the strong nonrepudiation, strong unforgeability and ...

Parallelized Pollard's Rho algorithm for ECDLP on Graphic Cards

2010
The recent introduction by NVidia of Compute Unified Device Architecture (CUDA) libraries for High Performance Computing on Graphic Processing Units has started the trend of video cards for resolution of many computationally hard problems in different areas like fluid dynamics, molecular dynamics, computer vi- sion and astrophysics.

Secure ID-Based Blind Signature In ROM Under ECDLP

The blind signature system is a type of digital signature in which the contents of the message are hidden. The blind signature created can be publicly validated against the original. There have been lots of ideas for ID-based blind signature schemes, many of which are insecure and inefficient.
