Embodiment
A kind of encryption device, have the binary data of Changing Pattern separately by at least two groups and generate redundant data when be-encrypted data is encrypted, by described redundant data, be-encrypted data is encrypted, and by mapping operations, further obtains enciphered data.Above-mentioned encryption device has the data of Changing Pattern separately by at least two groups and generates redundant data, make the enciphered data complexity that obtains higher,, even above-mentioned enciphered data can not decoded easily by being intercepted and captured also in transmitting procedure, prevent that the leakage of important information, fail safe are stronger.
Below in conjunction with drawings and Examples, a kind of encryption device of the utility model is described in more detail.
Figure 1 shows that the encryption device module map of the utility model one embodiment.
With reference to figure 1, a kind of encryption device, comprise the first maker 110 and the encrypting module 130 with the first Changing Pattern formation base data of electrical connection.The first maker 110 generates has the basic data of the first Changing Pattern, and encrypting module 130 generates redundant data and by above-mentioned redundant data, be-encrypted data is encrypted and obtains enciphered data as basis take above-mentioned basic data.
Above-mentioned encryption device generates redundant data by one group of data that constantly change, and, even make important information more hidden and make enciphered data repeatedly be intercepted and captured and also be difficult for being cracked in transmitting procedure, has guaranteed the fail safe in the encrypted data transmission process.
Shown in Figure 2, be the encryption device module map of another embodiment of the utility model.
With reference to figure 2, above-mentioned the first maker 110 comprises the high-speed counter unit 112 of at least one cascade, the count value that the above-mentioned basic data that generates take the first Changing Pattern produces by counting as the high-speed counter unit 112 of cascade, above-mentioned the first Changing Pattern is the rule of above-mentioned count value variation.
In other embodiments, above-mentioned the first Changing Pattern also can refer to other existing binary data with certain Changing Pattern, is not limited to the Changing Pattern of the count value that above-mentioned high-speed counter unit 112 produces.Accordingly, in other embodiment, above-mentioned the first counter 110 also can generate other and have the data of certain Changing Pattern, is not limited to the count value that above-mentioned high-speed counter produces.
Concrete, above-mentioned high-speed counter unit 112 is MC74HC4020AD high-speed counter chip, can produce the binary counting of 14 during each chip counter.When above-mentioned high-speed counter unit 112 numbers are 6, produce the count results of 84 as basic data.
Above-mentioned high-speed counter refers to calculate than plain scan frequency pulse signal faster, and its operation principle and general counter are similar, just the response time of counting channel shorter, generally with the frequency of KHZ, count.Concrete, the precision of above-mentioned high-speed counter can be 30MHZ, and expression can be counted 300,000,000 times in 1 second.Relative, if the figure place of above-mentioned basic data is higher, the complexity of the enciphered data that generates later is higher, thus the fail safe in above-mentioned encrypted data transmission process is also just relatively higher.
Along with the continuity of time, the count results that above-mentioned high-speed counter unit 112 produces constantly increase until while reaching default count results automatic clear then restart counting.In order to reduce when enciphered data is intercepted and captured in the process of transmission the probability that is cracked, the count results that above-mentioned expectation is set is prime number.
When above-mentioned basic data be the high-speed counter chip produce count value the time, the Changing Pattern of above-mentioned basic data automatic clear and restart to count when counting down to a predetermined count value when high-speed counter., if basic data is a count value that continues counting always,, if enciphered data is is repeatedly intercepted and captured in the encrypted data transmission process, also there is the possibility that is cracked.So,, by above-mentioned count value automatic clear and restart counting when counting down to a predetermined count value is set, make enciphered data more complicated, reduced the possibility that is cracked when above-mentioned enciphered data is is repeatedly intercepted and captured in transmitting procedure.
Above-mentioned predetermined count value is a relatively large prime number of numerical value in the maximum magnitude of above-mentioned basic data.Above-mentioned prime number is a set point, can be a prime number maximum in basic data figure place scope.Prime number claims again prime number, refer to one greater than 1 natural number in, except 1 and this integer self, the number that can not be divided exactly by other natural numbers.Number is closed in be called relative with prime number, close number refer in natural number except can by 1 and itself divide exactly, the number that can also be divided exactly by other number.When enciphered data is deciphered, if being one, redundant data closes number, be conducive to the deciphering of enciphered data, and basic data is unfavorable for the deciphering of above-mentioned enciphered data while being set to prime number, even when above-mentioned enciphered data is intercepted and captured or is is repeatedly intercepted and captured, also be difficult to crack, further improved the fail safe of enciphered data.
If above-mentioned basic data be one group along with then the continuous regular increase of time lengthening, zero clearing continue to increase,, if in the enciphered data that generates thereafter, repeatedly intercepted and captured, also have the possibility that is cracked.So also can generate by above-mentioned the first maker 110 combination of the continuous change count value that is produced by several groups of high-speed counter chips, wherein every batch total numerical value can start with different counting initial values to count and automatic clear and restart counting respectively while reaching the pre-set count values of setting separately, increase the complexity of basic data, improved the fail safe in the encrypted data transmission process.
