Description
Technical field
The utility model belongs to information security field, especially a kind of device of encrypting and decrypting of the high safety that contains human body information.
Background technology
In recent years, along with the fast development of computer networking technology, the research of the encrypting and decrypting method of required high safety receives the very concern of height in the data communication at computer.There are a large amount of patents and research paper to be delivered.Now set forth the present situation in this field and the problem of existence with regard to quoting several the patents of delivering recently.
With fixed rule be key with clear data by given array, thereby realize encrypting the purpose that obtains ciphertext through combination, the gimmick of the representational practicality in the world is the DES (Data Encryption Standard) of 64 bit encryptions and AES (Advanced EncryptionStandard) algorithm of 128 bit encryptions at present.Research does not in this respect have at present breakthrough progress as yet, as the up-to-date patent of Japan, " secret signal communication means; secret signal communication system, secret signal communicator and secret signal signal procedure " [spy opens 2006-333095] this patent of being delivered by the Japanology person that is entitled as only proposes the code that sets in advance in the employing equipment in the generation of key.
Japan famous copier manufacturer R society has also delivered recently and has been entitled as " facsimile machine device; personal computer and facsimile machine trusted document are joined communication system " [spy opens 2006-332902] this patent and has proposed adding the scheme of password in communicating by letter between facsimile machine and server or the computer, with the content of solution facsimile machine can be easily by the third party steal problem.
Above patent still adopts traditional gimmick on the algorithm of encrypting and decrypting.But be noted that the DES (Data Encryption Standard) of 64 traditional bit encryptions and AES (the Advanced Encryption Standard) scheduling algorithm of 128 bit encryptions, belong to the form of the block encryption (Block Cypher) of shared key.Though the method computational speed of traditional block encryption is fast, the practicality height exists by known plaintext than the shortcoming that is easier to release the ciphertext content, and utilizes special test data deducibility to encrypt the shortcoming of rule.BBS (Blum-Blum-Shub) method as the representative form of continuous encryption (Stream Cypher), the encryption that the theory of utilization value of two prime numbers of difficult deduction from the product of two enough big prime numbers realizes, encrypting with this method needs long computing time, but encrypted result is acknowledged as to make up entirely and just can cracks content expressly.Fuji Tsu adopts a large amount of big prime number heuristics but the Economic News of on September 1st, 2006 Japan has just been reported for work, and has just cracked the result of 128 bit encryptions in less than one month time.
Represent the up-to-date cryptographic algorithm of Japan, by the state-run Hiroshima University of Japan, the water university of state-run tea, the patent of researcher's co-present of chevron university is entitled as " simulation random number generation systems, secret signal system and multiple number change system " (spy opens 2006-317802).This method belongs to the form of continuous encryption (Stream Cypher), to be the PN random number series of safety inadequately that shared key generates at first by the preprepared ordered series of numbers, and then with safe inadequately PN random number series, be transformed into safe SPN random number series, concrete grammar is that last one numerical value is existed in the internal memory, obtains being called as safe SPN random number series by each that calculates the PN random number series with last one logic multiply.At last, will expressly carry out the calculating of logic XOR, draw the ciphertext after the encryption with the SPN random number series.The inventor is called Mersenne Twister simulation random number series method with this method, and its effect is that the cycle of the random number series after the encryption of exporting is 2
19937-1, longer than the cycle of traditional random number series, computational speed is fast etc.Shortcoming is that hardware spending is bigger, and 623 32 code need leave in the internal memory, and when both having needed 19936 random number series, particularly initial value to be " 0 ", state space is that the numeric ratio of " 0 " is more.Exception because of the simulation random number series that produces is to draw by fairly simple computing, therefore still exists by special ordered series of numbers, might extrapolate the problem of encryption rule.
In addition, any encryption method no matter traditionally, because of the code form before encrypting with encrypt after code form be similar binary code, therefore exist the problem that methods such as using the current language display rule all can be cracked to the file of its encryption.
Have, what make us perplexing most in the encrypting and decrypting field is that a good cryptographic algorithm has just lost its value after being disclosed again.Up to the present the algorithm that nearly all in the world algorithm all is a single form, therefore in a single day good again algorithm is disclosed, and the assailant always can seek out the means that crack according to the rule of cryptographic algorithm.Therefore, people thirst for seeking computational speed that a kind of variable multiple algorithm merges again than encryption method faster.
Deliver with the form of patent about the ordered series of numbers that utilizes human body information to generate to have true random distribution nature, its exercise question is: " containing human body information ID code generating method " (031003621).This patent does not relate to the content of the encrypting and decrypting aspect that contains human body information, and the present embodiment just is based on this method and proposes to utilize human body information to carry out the application of encrypting and decrypting.
About the representational patent of the Information Hiding Techniques of imbedding information in printing in the image respectively in Japan's (spy opens 2006-319632), the U.S. (US-2006-0256386-A1) is disclosed, in China (200610008124.X) application, be entitled as " the generation method of information embedded halftone screen code ".The present embodiment hides Info in the image at the 2 d code that is adopted after the encryption and in printing and just is based on this method and is proposed.
About in electronic image, imbedding the Information Hiding Techniques Japan representational patent " image sale device, image is bought device, method and program " (spy opens 2004-96450) of information.This patent imports and is called as the Steganography method, utilizes the bit image on upper strata that original image is influenced smaller principle, can imbed to hide Info in the bit image on upper strata.The present embodiment realizes by this method at hiding Info in electronic image.
