摘要: A secret communication method and a device used in the are provided for using path less frequently as whole while avoiding duplicative use of public communication. The includes steps of: estimating an error ratio initial random numbers X, Y; upper limit eavesdrop information amount; determining encryption function determined by correction code based on estimated probability, decoding g, decryption auxiliary variable; uniquely confidentiality increase matrix C value amount encoding code; generating ciphertext Z from M to be sent receiver function, number C; transmitting Z; decrypting transmission text B Y, C, variable, g.
