Encryption type transmission method for transmitting digital information based on 5G network

Abstract

The invention discloses an encryption type transmission method for transmitting digital information based on a 5G network, and aims to solve the problems that in the prior art, an information source and a channel are not coded, so that error codes are generated in the transmitted data stream, the phenomena of image jumping, discontinuity and the like are generated at a receiving end, and the error correction capability and the anti-interference capability are poor. The method comprises the following steps: S1, carrying out information source coding on an information source so as to reduce or eliminate data redundancy; s11, an information source symbol set A = a1, a2, aN and has N symbols in total, and an input signal source symbol sequence U = (u1, u2, uL); s12, in the ith step, the encoder starts to search the shortest short language which never appears before from the first symbol behind the-1 phrase backwards. According to the method, the key stream generator is adopted to generate the stream password, and the plaintext and the key are subjected to XOR processing to obtain the ciphertext, so that the security of digital information is improved, the capability of resisting various interferences when data are transmitted in the channel is enhanced, and the communication effectiveness is improved.

Description
