Abstract

The embodiment of the invention discloses a method for generating a key, a service node device and a computer readable storage medium. The method comprises the steps of if receiving an encryption keyobtaining request sent by a server, according to a service type carried by the encryption key obtaining request, determining a first root key identifier corresponding to the service type, wherein theencryption key obtaining request is sent from a client to the server; obtaining a first plaintext root key corresponding to the first root key identifier; generating an encryption key according to thefirst plaintext root key, the service identifier carried by the encryption key obtaining request and a preset data key generation algorithm; and sending encryption information carrying the encryptionkey and the first root key identifier to the server, such that the server forwards the encryption information to the client. According to the method for generating the key, the service node device and the computer readable medium disclosed by the embodiment of the invention, the cost of data encryption can be saved, and the efficiency of data encryption is improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method for generating a key, a service node device and a computer-readable storage medium. Background technique [0002] With the continuous development of Internet technology, Internet-based cloud storage technology has been widely popularized. When performing data storage or data backup, in order to save local storage space, more and more users choose to store or backup data to cloud servers. In order to ensure that the user data stored on the cloud server is not stolen, it is necessary to encrypt the data stored on the cloud server. [0003] In the prior art, the data stored on the cloud server is encrypted or decrypted by a highly secure hardware encryption machine. However, the cost of the hardware encryption machine is high, and when encrypting or decrypting a large amount of data, the efficiency of data encryption or decryption will be reduced due to the la...
