Abstract

The present application relates to a data decryption processing method, a data encryption processing method and a device. The data decryption processing method includes: receiving the first security sequence sent by the host; determining the encryption algorithm according to the duty cycle of the first security sequence; receiving the third security sequence sent by the host, and performing the third security sequence according to the key and the encryption algorithm; Decrypt to obtain the second security sequence; the key is determined according to the set pull-down time and the preset coefficient, the third security sequence is the ciphertext of the second security sequence, and the second security sequence is the target to be obtained from the host Raw data. The encryption algorithm is selected through the duty ratio of the first security sequence sent by the host, and the slave sets a key and provides it to the host for encryption processing. After the slave machine decrypts the third security sequence according to the selected encryption algorithm and key, the original second security sequence can be obtained, which greatly improves the security of data transmission.

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...
