Proxy Blind Multi-signature Scheme using ECC for handheld devices

Jayaprakash Kar


A proxy blind signature scheme is a special form of blind signature which allowed a designated person called proxy signer to sign on behalf of two or more original signers without knowing the content of the message or document. It combines the advantages of proxy signature, blind signature and multi-signature scheme. This paper describes an e±cient proxy blind multi-signature scheme. The security of the proposed schemes is based on the di±culty of breaking the one-way hash function and the elliptic curve discrete logarithm problem (ECDLP). This can be implemented in low power and small processor handheld devices such as smart card, PDA etc which work in low power and small processor. This scheme utilizes a trusted third party called certificate authority to ensure that signatures can only be generated during valid delegation period. It satisfies the security properties of both proxy and blind signature scheme.
