A proxy partially blind signature approach using elliptic curve cryptosystem
Partially blind signature is cryptographic system that is used in several protocols including e-cash and e-commerce systems. In proxy partially blind signature, part of the message is approved by the signer and the signature supplicant. Elliptic curve discrete logarithmic (ECDL) is an extremely difficult to solve problem as compared to any standard inverse operation of a one-way-trap door funct...
متن کاملDigital Signature based Proxy Multi-Signature Scheme
A Proxy signature scheme enables a proxy signer to sign a message on behalf of the original signer. In this paper, we propose ECDLP based solution for chen et. al [1] scheme. We describe efficient and secure Proxy multi signature scheme that satisfy all the proxy requirements and require only elliptic curve multiplication and elliptic curve addition which needs less computation overhead compare...
متن کاملA New Proxy-Protected Signature Scheme Based on DLP
Received Sept 03 th , 2012 Accepted Sept 24 th , 2012 During electronic communication, proxy signature helps the signer to sign message on behalf of the original signer. This type of signature scheme is used when the signatory is not available to sign this document. In this paper, we propose a new protected proxy signature scheme. In the proposed scheme, the proxy signer can sign message on beh...
متن کاملNotes on Proxy Signcryption and Multi-proxy Signature Schemes
Proxy signcrytipn scheme allows an original signer to delegate his signing power to a proxy such that the latter can signcrypt a message on behalf of the former. Recently, Lin et al. proposed a proxy signcryption with CCA and CMA security. In this work, we indicate that the Lin et al.’s proxy signcryption scheme does not hold the security of indistinguishability against adaptive chosen-cipherte...
متن کاملAn Efficient Self Proxy Signature Scheme Based on Elliptic Curve Discrete Logarithm Problems
Self proxy signature is a type of proxy signature wherein, the original signer delegates the signing rights to himself, there by generating temporary public and private key pairs for himself. The aim of self proxy is to protect the signer's permanent secret key. Most of proposed self proxy signature scheme have been based on discrete logarithms which required for a protocol to generate and veri...
