Encryption mode combined with file structure

Abstract

This invention discloses an encryption mode of combinated of information structure. This mode includes a separate unit, a group unit and the plural encryption modules. The separate unit separates a document into plural information sections. According to a multiple-element information structure, the group unit divides the information section into plural information section group. Finally, it uses the plural encryption modules for computing the encryption algorithms in order to generate the encrypted information sector group. Thereby, it achieves to shorten the encryption time and improve the encryption speed.

Description

technical field [0001] The present invention provides an encryption method using a multivariate data structure and a system thereof, in particular about utilizing at least one multivariate data structure for encryption processing. Background technique [0002] In today's society, due to the development of network technology, traditional written documents have gradually been replaced by electronic documents. With the prevalence of electronic documents, in order to prevent electronic documents from being intercepted by interested parties during transmission, it is necessary to rely on the encryption of electronic documents . Please refer to FIG. 1 , which is a block diagram of an encryption system in the prior art using an electronic codebook encryption system (Electronic CodeBook: ECB) as an embodiment. [0003] The division unit 12 divides a data 11 to generate a plurality of data segments 13 , and then, the encryption calculation unit 14 performs an encryption operation on...

Problems solved by technology

[0006] However, if the encryption method of the aforementioned prior art is carried out in a context-independent manner, when the encryption key of one of the encrypted data segments is cracked, the tampered encrypted data segment cannot be detected at the receiving end , so the security of the file is relatively insufficient. If the encryption method related to the context is used, when the encryption key of one of the encrypted data segments is cracked, the tampered encrypted data segment will affect the entire file. Whether the file can be decrypted, so that the receiving end can notice that the file has been tampered with, so the security of the file is better

However, the encryption method related to the context needs to wait for the encryption of the previous text to be completed before the subsequent text can be encrypted. It is impossible to encrypt other data at the same time.

Therefore, when the file content is huge or the number is large, the user needs to spend a lot of time waiting, which is very inconvenient
