Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, the process that the present invention carries out dynamic token intelligence time bias is following:
(1) in the dynamic token production process, through measuring the crystal oscillator time deviation of dynamic token, through periodically observing the dynamic token time deviation.
(2), and obtain dynamic token timing intelligent compensation straggling parameter value with this according to the periodic Changing Pattern of dynamic token time deviation.
(3) dynamic token is adjusted the crystal oscillator time deviation time of dynamic token according to the dynamic token timing intelligent compensation straggling parameter value of step (2) acquisition when generating dynamic password.
(4) time and the seed key of dynamic token after with compensation adjustment carries out cryptographic calculation, with the operation result brachymemma and convert into and can show number, generates 6 or 8 dynamic password with this.
(5) user uses this dynamic password to carry out password authentication.
The realization principle of step 2 is following among the present invention:
Referring to Fig. 3, realize the synchronous of two clocks, the one, the count value of clock is identical, and the 2nd, the counting rate of rise is identical.
Under the synchronous situation of dynamic token clock and UTC; If the frequency of UTC clock is f; Token clock is Y at n-1 to the n time period, and a+b=d is the time of delay of sync message from the UTC clock to token clock, can adopt back-and-forth method to measure through the Time delay measurement frame; This value d can think constant, has so:
X＝Y+d (1)
Wherein, X is the cycle time that UTC sends sync message.
If the dynamic token clock is asynchronous with UTC, wherein, Y ' be token clock at n-1 to n time period token counts time, Y " to be token clock arrive the time deviation of n time period at n-1, and the intelligent time bias of needs has so:
Y″＝Y-Y′(2)
Because the UTC clock is periodically to send sync message, is the per second calculated rate if adopt 128HZ.Can get by formula (1) and (2):
k＝X×128/(X×128-1000×Y″)
K is exactly a dynamic token timing intelligent compensation straggling parameter value.Can calculate the compensate parameter value in each synchronizing cycle, realize frequency adjustment through the relevant hardware circuit then.
Because middle result of calculation will be passed through certain clock cycle, so the crystal oscillator cycle that the latch signal of compensate parameter value k will be delayed time certain.Adopting 128HZ in the present invention is the per second calculated rate, promptly under the situation of＜1ms, just can obtain the dynamic token intelligent compensation time.
Dynamic token intelligence time compensating method can intelligence the deviation of crystal oscillator timing of rectification dynamic token, guarantee the time accuracy of token, stop the token step-out.
Based on such scheme, practical implementation of the present invention is following:
1, in the dynamic token production process, through measuring the crystal oscillator time deviation of dynamic token, the line period property of going forward side by side observation dynamic token time deviation obtains the periodic Changing Pattern of dynamic token time deviation.
2,, draw dynamic token timing intelligent compensation straggling parameter value according to the periodic Changing Pattern of dynamic token time deviation.
3, dynamic token generated in the dynamic password process in the later stage, and dynamic token intelligence time bias mode intelligence is adjusted the crystal oscillator time deviation time, guarantees the time synchronized of dynamic token.
In this step, dynamic token just directly adopts compensate parameter value k when Practical Calculation self system time, and under the ordering about of each k signal, dynamic token compensates Y automatically " is corresponding intelligent compensation time time period of compensate parameter value k.
4, dynamic token is through carrying out cryptographic calculation acquisition dynamic password (it is a prior art, does not give unnecessary details) here to adjusted time and seed.
5, the user uses this dynamic password to carry out dynamic cipher verification.
Adjust the crystal oscillator time deviation time with dynamic token intelligence time bias mode intelligence in the 3rd step among this embodiment, thereby guarantee the time synchronized of dynamic token.
