Abstract

The invention relates to a data decryption processing method and device and a data encryption processing method and device. The data decryption processing method comprises the following steps: receiving a first security sequence sent by a host; determining an encryption algorithm according to the duty ratio of the first security sequence; and receiving a third security sequence sent by the host, and decrypting the third security sequence according to the key and an encryption algorithm to obtain a second security sequence, wherein the secret key is a secret key determined according to set pull-down time and a preset coefficient, the third security sequence is a ciphertext of a second security sequence, and the second security sequence is target original data needing to be obtained from thehost. An encryption algorithm is selected through the duty ratio of the first security sequence sent by the host, and the slave sets a secret key and provides the secret key for the host for encryption processing. And the slave decrypts the third security sequence according to the selected encryption algorithm and secret key to obtain the original second security sequence, so that the effect of greatly improving the data transmission security is achieved.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a data decryption processing method, a data encryption processing method and a device. Background technique [0002] With the development of data transmission technology, data encryption and decryption transmission technology has been iteratively updated since its birth, and its application fields are also relatively extensive, such as system upgrades and chip access testing, etc., which are widely used. Data plays an important security role. Taking system upgrade as an example, each upgrade of production management software such as enterprise resource planning system, operating system, and operation system involves a series of operations such as database backup and log viewing when the upgrade fails. System upgrade requires short upgrade time and accurate upgrade data. For enterprise software, data is the core competitiveness, therefore, data security is on...
