Disk array and computer or storage medium authentication method and system

Abstract

The invention provides a disk array and computer or storage medium authentication method and system. The method includes the following steps that 1 a disc array control module of a credible disk array controls the credible disk array through a disk array controller module and conducts mutual authentication on a computer and a storage medium by utilizing a password authentication algorithm; 2 the computer or the storage medium passing the credible disk array authentication is authenticated to be a credible computer or a credible storage medium and is permitted to enter the credible disk array; otherwise, the computer or the storage medium is authenticated to be an illegal computer or an illegal storage medium and is prevented from being connected into the credible disk array. By means of the method and system, credible authentication between the disk array and the credible computer and between the disk array and the internal storage medium is achieved, and data on the disk array and the storage medium cannot be accessed illegally.

Description

technical field [0001] The invention relates to the fields of computer information storage technology and security technology, in particular to an authentication method and system between a trusted disk array and a computer or storage medium. Background technique [0002] As a large-capacity and reliable data storage device, disk arrays have been widely used. A large amount of data information is stored centrally in the disk array. In most applications, the system has very high requirements on the overall security of the disk array. [0003] The existing disk array does not follow the trusted computer architecture, and cannot realize the trusted chain of trust from the trusted computer to the disk array, and the disk array cannot implement trusted authentication for its internal solid-state disk, disk and other storage media. There are still certain hidden dangers in data security, such as: system administrators cannot be prevented from obtaining data by maliciously replaci...
