Code-based Certificateless Identification Scheme
Maoan Han · Journal of Liaoning Technical University · 2013
In view of the public key authentication scheme based on number theoretic has the problems of difficult to use in low resources environment, and in the quantum computer is no longer safe,this paper presented a new certificateless identification scheme based on coding. The new scheme achieves high efficiency by only using XOR operation, and handles problems of key escrow key, because of KGC does not have access to entities' private keys. Especially, this paper proposed to use quasi-cyclic code over Fq in order to dramatically reduce the size of the public key. The results show that this study provides a very practical identification scheme which is especially for light-weight cryptography. The new scheme laid a foundation for further practical of public-key cryptosystem based on error correcting codes.
