Description
Technical field
The present invention is for providing a kind of encryption method and system thereof that uses the multivariate data structure, particularly about utilizing at least one multivariate data structure, to carry out encryption.
Background technology
Society is because networking science and technology is flourishing, and traditional written document is replaced by e-file gradually now, and in vogue along with e-file by preventing that e-file from being had the inclination the personage and being intercepted in the process that transmits, just must be dependent on the encryption of e-file.See also Fig. 1, for the encryption system of prior art is the calcspar of embodiment with electronic type code book encryption system (Electronic CodeBook:ECB).
12 pairs one data of cutting unit 11 are done to cut apart, and produce a plurality of data segments 13, then, encrypt 14 pairs one data segments of calculation element 13 and carry out an encryption acts, produce a plurality of sections of encrypted data 15.Just a plurality of sections of encrypted data 15 can be carried out the networking then transmits.
Aforesaid way is and context free encryption mode, except above-mentioned electronic type code book encryption system, other most encryption modes all have context sensitive feature, continue, see also Fig. 2, for the encryption system of prior art is the calcspar of embodiment with cryptographic block link (Cipher Block Chaining:CBC).
12 pairs one data of cutting unit 11 are carried out one and are cut apart action, produce a plurality of data segments, and arithmetic element 21 carries out computing action with first data segment 231 and an initial vector value 22, produces one first data segment 241 to be encrypted.Arithmetic element 21 can be a mutual exclusion logical-arithmetic unit (XOR).Encrypt 14 pairs of these first data segments 241 to be encrypted of calculation element and carry out an encryption acts, to produce one first encrypted data section 251.Then, first encrypted data section 251 and second data segment 232 have carried out computing action to arithmetic element 21 according to this, produce one second data segment 242 to be encrypted, encrypt 14 pairs of these second data segments 242 to be encrypted of calculation element and carry out an encryption acts, to produce one second encrypted data section 252.Repeat above-mentioned action, to produce a plurality of sections of encrypted data.Just a plurality of sections of encrypted data can be carried out the networking then transmits.
Yet encryption method by aforementioned prior art, if to carry out with context free cipher mode, when wherein one when the encryption gold key of encrypted data section has been cracked, the section of being altered of encrypted data can't be discovered in receiving terminal, so it is comparatively not enough for safety of files, if carry out with context sensitive cipher mode, when wherein one when the encryption gold key of encrypted data section has been cracked, can the section of being altered of encrypted data can have influence on whole part of file decrypted, thereby can allow receiving terminal perceive file once to be altered, so preferable for safety of files.Yet context sensitive cipher mode hereinafter just can be encrypted after need waiting for that the preamble encryption is finished, and can't carry out the encryption of other data simultaneously.Therefore when file content during huge or One's name is legion, the user need spend many times in wait, and is very inconvenient.
For satisfying the demand that the above-mentioned minimizing that proposes is encrypted the time and taken into account fail safe.The inventor is based on going in for the study for many years and many practices, kindly add the benefit that the wafer application cost of manufacture descends and to be produced, again after research and design in many ways and special topic are inquired into, satisfy in the present invention and propose a kind of encryption method and system thereof with as aforementioned expectation one implementation and foundation.
Summary of the invention
Because above-mentioned problem, purpose of the present invention is in conjunction with a multivariate data structure for a kind of encryption mode that uses the multivariate data structure is provided, and a plurality of ciphering units are to carry out encryption acts, the stand-by period of encrypted data is significantly reduced, also can take into account the fail safe of encrypted data simultaneously.
Edge is for reaching above-mentioned purpose, according to a kind of encryption mode that uses the multivariate data structure of the present invention, to comprise step at least as back:
At first, cut apart pluralize data segment of a data; According to a multivariate data structure, those data segments are divided into a plurality of information data area stage groups; Use a plurality of ciphering units that those information data area stage groups are carried out encryption, to produce a plurality of section of encrypted data groups.
From the above,, see through at least one multivariate data structure and carry out data and encrypt, the time that can effectively reduce encryption and spent, also take into account the data safety of transmission because of providing a kind of encryption mode according to of the present invention.
