Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] see figure 1 The first embodiment of the technical solution provides a data processing method, comprising the steps of:

[0045] S101, the receiver and the sender negotiate to generate a key pool and determine the same pseudo-random number generator.

[0046] In data communication, there are usually two parties involved in the communication, that is, the sender and receiver of the data. In this step, the sender and the receiver generate multiple shared keys through negotiation, and the multiple shared keys form a key pool. The number of the encryption keys can be set as required. When th...

Abstract

The invention provides a data processing method, comprising the steps of: a receiver and a sender generating a key pool through negotiation, and determining a same pseudo random number generator; the sender operating the pseudo random number generator to obtain a pseudo random number, selecting a key from the key pool according to the pseudo random number, encrypting a current data set to be sent by the key, and sending an encrypted data set to the receiver; and the receiver operating the pseudo random number generator in a same mode with the sender to obtain a pseudo random number, selecting a corresponding key from the key pool in a same mode with the sender according to the pseudo random number, and deciphering the encrypted data set by the corresponding key. The invention also provides a data processing system. The data processing method and system solve the problem of low key service efficiency in a data processing process of the prior art, and reduce a key updating frequency.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a data processing method and system. Background technique [0002] In communication systems, in order to ensure the confidentiality of data, symmetric encryption algorithms are often used. That is to say, when sending data, the sender in the communication system first encrypts the sent data, and after receiving the encrypted data, the receiver needs to use the same password to decrypt the data. However, the key in the encryption and decryption process cannot be used indefinitely, because the more data encrypted with a certain key, the greater the chance of the password leaking; The more data a key encrypts, the greater the loss. [0003] In order to ensure the security of the key in symmetric encryption, usually a certain key is used to encrypt a certain amount of data or after a certain period of time, the key must be discarded and a new key used instead. This o...
