Embodiment Construction
[0066] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0067] Aiming at the deficiencies of the prior art, the present invention proposes an anti-leakage one-time pad communication method, such as image 3 shown, including:
[0068] S1, the sender generates ciphertext from the one-time key read from the cipherbook according to the active reading method and the plaintext to be sent through the preset encryption algorithm;
[0069] S2, after pack...

The invention provides an anti-leakage one-time pad communication method and device, comprising: the sender generates a ciphertext from the one-time key read from the cipherbook according to the active reading mode and the plaintext to be sent through a preset encryption algorithm; After the ciphertext and the codebook location range corresponding to the one-time key are packaged, they are sent to the recipient through a public channel; the recipient reads the codebook from the codebook in a passive manner according to the codebook location range A decryption key: performing a decryption operation on the decryption key and the ciphertext through a preset decryption algorithm to obtain received plaintext. The invention solves the problems of key leakage and difficult complete destruction of the one-time pad in the actual use process by using the key for one-time reading and writing to encrypt and decrypt; by introducing two methods of reading the key, active and passive, This method ensures that each key is only used once for one message, which solves the problem of the one-time key being reused.
Description
technical field [0001] The invention relates to the technical fields of encrypted communication and network security, in particular to a leak-proof one-time pad communication method and device. Background technique [0002] In order to ensure the confidentiality of communication, the one-time pad is proved to be an absolutely secure means of communication encryption. The one-time pad cipher was first invented by Major Joseph Mauborgne and Gilbert Vernam of AT&T in 1917. [0003] When using the one-time pad method for encrypted communication, the following conditions must be met to ensure the absolute security of communication: [0004] (1) The key must be a true random sequence; [0005] (2) The key length is at least as long as the plaintext; [0006] (3) Each key is only used once for a message and cannot be reused; [0007] (4) The key cannot be disclosed during transmission. [0008] Correspondingly, a one-time pad (One Time Pad) is a typical one-time pad communicati...
