Problems solved by technology

[0003] In practical applications, encryption and decryption devices are usually used to encrypt and decrypt communication information, but when the amount of communication information is too large, the encryption / decryption processing of the full text of communication information will consume a lot of time and memory of the encryption and decryption device. Affect the processing speed of the encryption and decryption device, reducing the output speed of information

Abstract

The present invention provides an encryption / decryption device and an information processing method and system. The information processing method comprises: a decryption device obtaining a coded data packet, the coded data packet comprising communication text and control information of the communication text, the communication text comprising plaintext and at least one section of ciphertext, and the control information comprising ciphertext identifier information of the ciphertext; the decryption device determining ciphertext of the communication text according to the ciphertext identifier information of the ciphertext in the control information; the decryption device obtaining a decryption policy corresponding to the ciphertext; the decryption device performing decryption processing on the obtained ciphertext by using the decryption policy, so as to obtain character information; and the decryption device triggering an operation of outputting the character information.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an encryption and decryption device, information processing information and a system. Background technique [0002] In order to ensure the security of communication information such as emails and instant messages, in the prior art, the sender encrypts the full text of the communication information before sending it out. Correspondingly, after receiving the encrypted communication information, the receiver uses the corresponding decryption algorithm Only by obtaining the full text of the communication information can the content of the communication information be obtained. [0003] In practical applications, encryption and decryption devices are usually used to encrypt and decrypt communication information, but when the amount of communication information is too large, the encryption / decryption processing of the full text of communication information will consume a lot of tim...
