Problems solved by technology

[0005] Therefore, it is necessary to develop a new key management system and method, which can store key codes in multiple data cards, and only need more than a certain proportion of data cards to restore the original key code order, so as to solve the defect that the key cannot be restored normally due to the absence of some data cards in special cases

Embodiment Construction

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following describes the present invention through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0027] figure 1 The flow chart of the data distributed storage method according to the preferred embodiment of the present invention is shown.

[0028] The data distributed storage method of this embodiment is used to implement data backup and restoration. In this embodiment, the number of data packets is set to m to realize n backup. That is, the original data is set to be scattered and stored in m data cards according to certain rules, that is, m data ca...

Abstract

The invention discloses a data scatter storage method, a data recovery method and a data card which has the functions of data scatter storage and cross recovery. According to the technical scheme provided by the invention, original data can be stored in a scattered manner in a plurality of data cards according to a predetermined rule, so that each data card automatically stores corresponding part of data according to the serial number index of the card and stores part of data in other data cards in a cross mode. Therefore, original data stored in all data cards can be recovered just by the any more than half of data cards. Efficient, convenient and raid data reduction is realized while data is safely protected.

Description

Technical field [0001] The invention relates to a data distributed storage method and a restoration method, and a data card capable of implementing the method. Background technique [0002] At present, the key management system usually uses multiple data cards to store part of the key data of the key code sheet. The leader with management authority holds a data card, the so-called leader card or key card. When the key is restored , Then all the leadership cards are required to participate together, and to increase the part of the key data stored in each, in order to restore the complete key code list. This kind of key management system reduces the possibility of key leakage and effectively guarantees the security of the system by dispersing the key code sheet (usually longer) in the hands of multiple people. [0003] However, a serious problem with this key management method is that all data cards must participate in order to restore the key data. When individual data card holder...
