Most of the currently used identification schemes can not be safely used if factoring factorization and discrete logarithm problem are solved efficiently.In response to such problems, many identification schemes having tolerance have been proposed.Although there is an improved scheme to reduce the key size by using the public matrix having the cyclic structure, various attack algorithms have been proposed with the cyclic structure as a weak point.In this paper, we propose an identification scheme that has tolerance and small key size and computational complexity.The key size is reduced by making the parity check matrix of the public key a matrix composed of blocks of cyclic matrices of a plurality of stages.In order to cope with existing attacks with a weak point in the cyclic structure, the cyclic structure is eliminated for the entire codeword.
Furthermore, we show that the calculation matrix can be reduced by making the public matrix dense.We also evaluate the security level, key size, computational complexity and safety of the proposed scheme. |
