Abstract

The invention provides a dynamic deletion encryption system, which comprises a processing module, a segmentation module, a random module, a deletion module, a transmission module and an identity module, and is characterized in that the processing module is used for carrying out encryption processing on a plaintext to obtain a ciphertext and carrying out decryption processing on the ciphertext to obtain the plaintext; the segmentation module is used for segmenting the ciphertext to obtain a plurality of ordered ciphertext packets, the random module is used for generating a string of random number sequences, the number in the number sequences is the same as the number of the ciphertext packets, and the missing module extracts corresponding contents from the ciphertext according to the random number sequences and sends the corresponding contents to the storage module. The missing module constructs the extracted content and a random number sequence into a missing data packet, the transmission module is used for transmitting data between two terminals containing a system, and the identity module is used for performing identity verification on the terminals participating in transmission; according to the system, the ciphertext is divided into the ciphertext packet and the missing packet, and the missing packet is sent after the ciphertext packet is correctly received, so that the security of the transmission content is improved.

Description

technical field [0001] The invention relates to the field of encrypted transmission of digital information, in particular to a dynamic deletion encryption system. Background technique [0002] The encryption system is a very important part of the information transmission process. With the development of the Internet and the huge increase in the amount of information transmission, the importance of the encryption system is also increasing. The encryption method is constantly developing, and the cracking method is also improving accordingly. The development of a more difficult to crack encryption system is needed in the current environment, and the lack of encryption is one of the directions. In the existing lack of encryption Improving security is a problem that needs to be solved at present. [0003] The foregoing discussion of the background art is merely intended to facilitate an understanding of the present invention. This discussion does not endorse or acknowledge any ...
