Diastema password digit m and preset relation determine time delay multiple z；The user password digit is estimated according to selected terminal platform
The required checking time tn that n is verified；When the diastema password for obtaining user's input is verified according to default time delay, to described
Default time delay determines that verifying is completed after reaching, and executes subsequent operation according to verification result, by way of increasing and verifying time delay,
In the case where not influencing user experience, the safety that diastema password uses is improved.
For safety check diastema cryptographic methods provided by the invention, demonstrate,proved below by the test for carrying out safety
It is bright.
For the random fixed digit password of user's input, attacker depends on fixed position by the probability of Brute Force
Number.For example, for numeric keypad 0~9, user sets unlocking pin 6, then by enumerate crack successful probability be 10^ (-
6) is desired for 10^6, this is a bigger trial and error number for attacker.
In GA374-2001 electronic safety lock standard, size of key is defined, it is specified that using electronic code electricity
Sub- theftproof lock A grades of size of keys should be no less than 10^5, and B grades of size of keys should be no less than 10^6.However the introducing of diastema password will so that
Input length becomes larger, so that collision probability is promoted, and then reduces actually active size of key.
Definition b is Password Input space digit, and n is the practical true user password length of verification；M is the void for allowing to input
Position Password Length, by diastema password it is found that m >=n, and m=np+q, p are m divided by the integer of n, and q is remainder；
It defines, the probability containing n user passwords is P in m virtual pins(b,m,n), then formula (1)
As shown in connection with fig. 2, because this is sufficiently small when n is larger, the function is similar compared with curve shape.Pass through
Matlab, which is drawn, works as b=10, i.e., the probability curve (3 < n < 11,7 < m < 21) under numeric keypad, and m is coordinate, in n in probability curve
It is poor with the safety of m diastema password when lesser, and this is current typical application scenarios, wherein 1, m it is bigger, collided
Probability it is bigger, but probability is increased speed compared to slowing down, until collision probability levels off to 1.2, n is smaller, more dangerous, identical general
The m digit needed under rate is also smaller.In view of being mainly 5 or 6 and being numeric keypad using n digit under reality
Under, we list the collision probability under typical m number:
When m is smaller, such as table 1.
Table 1
When m is larger, such as table 2.
Table 2
As representative value m=20, n=5,16 times are promoted by collision probability.
As representative value m=260, n=5,276 times are promoted by collision probability.
Brute Force is unlocked the expected time
Setting user password length n is fixed, and key input space digit b is fixed, if the diastema password of i-th user input
Length is then to open the number X expectation of lock:
WhereinFor formula (1)
The uncaging time for defining i-th user input is that then Brute Force opens the time Y expectation of lock are as follows:
In order to simplify processing, the input m that unlocks every time is seti, the distribution of ti is identical, thenti=tj=t, then expected time are as follows:
The P=b for not supporting commonly the keyboard of diastema password to unlock-n, i.e. the unlocking expected time is b-n×t。
From safety perspective, when the unlocking expected time of diastema password should not be below the unlocking of ordinary password keyboard
Between, it may be assumed that
Note
When m is smaller, the value of Z such as table 3:
Table 3
When m is larger, the value of Z such as table 4.
Table 4
By comparison it can be found that 5 user keys of the support 20 diastema passwords using classics, proving and comparisom
When time is greater than 16 times of commonly 6 passwords of verification, safety is suitable.

It completes to verify after verification z times of tn duration of time delay after each diastema Password Input finishes, be prompted if correct
Password is correct, prompt cipher mistake and re-enters if mistake.
6. a kind of safety check diastema encryption apparatus, which is characterized in that described device includes:
Acquiring unit, for obtaining the diastema password position of password key maximum quantity b, user password digit n and user's input
Number m, wherein the diastema password digit m=np+q, p are integer of the m divided by n, q is remainder, and p and q are positive integer；
Processing unit, for utilizing the password key maximum quantity b, the user password digit n, the diastema password digit
M and preset relation determine time delay multiple z；
When processing unit is also used to estimate the required verification that the user password digit n is verified according to selected terminal platform
Between tn；
Processing unit is also used to verify when the diastema password for obtaining user's input according to default time delay, to the default time delay
It determines that verifying is completed after reaching, subsequent operation is executed according to verification result.
7. safety check diastema encryption apparatus according to claim 6, which is characterized in that the preset relation are as follows:[] is round numbers to the right, the processing unit
It is specifically used for:
Utilize the password key maximum quantity b, the user password digit n, the diastema password digit m and preset relation
It is rounded numerical value to the right, the time delay multiple z is rounded to the right numerical value greater than described.
8. safety check diastema encryption apparatus according to claim 6, which is characterized in that the processing unit is also used to work as
When the remainder q is greater than 0, duplication check input n diastema password [z/ (p+1)] -1 time after n diastema passwords of every verification will most
A check results are determined as approving result afterwards.
9. safety check diastema encryption apparatus according to claim 6, which is characterized in that the processing unit is also used to work as
When the remainder q is equal to 0, duplication check input n diastema password [z/p] -1 time after n diastema password of verification every for terminal,
Last time check results are determined as to approve result.
10. a kind of intelligent lock, which is characterized in that there is processor and memory, the processor is for executing the storage
The program of device storage, the program for executing such as any one of claims 1 to 5 the method is stored in the memory.
