This paper firstly briefed the basic concepts of N public key cryptosystem, RS code and QC-LDPC code, and then put forward the cascade cryptosystem with the RS code being the outer code and QC-LDPC code being the internal code. At last, the writer analyzed in detail the security and performance of the N cryptosystem based on double public key, and thus proved its better security and performance than the traditional public key cryptosystem based on error correcting code. In addition, it is also endowed with higher practicability in complex environment.
