Abstract

The invention relates to a decryption method, device and system, a medium and equipment. The decryption method comprises the following steps: receiving a decryption request which is sent by first equipment and comprises authentication information; judging whether the decryption request is allowed or not based on the authentication information; and if the decryption request is allowed, sending thedecryption request to second equipment to enable the second equipment to send decryption information to the first equipment so as to enable the first equipment to execute decryption operation. On thebasis of an automatic decryption technology, a decryption verification step is added, and a decryption request is authenticated; and meanwhile, the decryption request and the decryption information are sent in an https protocol mode, so that the safety of the decryption information and the reliability of a decryption system are improved while automatic decryption of the hard disk is realized and the safety of data in the hard disk is ensured.

Description

technical field [0001] This article relates to the field of network security, especially a decryption method. Background technique [0002] When the physical server is in an unsafe environment, in order to ensure data security, there is a need for system disk encryption. However, after the system disk is encrypted, each time the server is restarted, a password must be entered to decrypt the hard disk before re-entering the system. Moreover, when entering the password, it is necessary to manually connect the monitor and keyboard to operate, and this method of operation not only increases the risk of password leakage, but also becomes inoperable when there are many servers. In view of the above deficiencies, the automatic decryption technology is introduced, that is, the auxiliary decryption information is placed on the web server. When the encrypted server needs to be decrypted, the auxiliary decryption information is obtained from the web server, and the auxiliary decryption...
