Identity-based Blind Signature Scheme Based on the Standard Model
Lei Xu · Journal of Shanxi University · 2012
An identity-based secure blind signature scheme based on the standard model was introduced,because the implementation process of random oracle model presenced security defect.First,the security model of identity-based blind signatures was delimited;second,blind signatures was proposed by bilinear pairing;finally,the proof of scheme's security was given in the standard model,which based on the Computational Diffie-Hellman assumption.Therefore,the scheme is security under adaptive chosen message and identity attacks.
