Wherein, according to the CIPHERING REQUEST, an at least mode for dynamic digital key for data encryption key is selected, is wrapped
Include the following two kinds mode:
Mode one: with reference to shown in Fig. 2A, it is assumed that there are four word bit, i.e. password is Password Input frame (password set interface) tool
Four.Can choose data encryption key wherein at least one word bit according to user instructions is dynamic digital key, such as is selected
Third position is selected.With reference to Fig. 2A, user has selected clock icon corresponding with third password position, i.e., expression user has selected the
Three password positions are as dynamic digital key.
Mode two: first according to the CIPHERING REQUEST, the number of the data encryption key of user's input is received.And then it obtains and is somebody's turn to do
The system time of terminal, judge user input data encryption key number whether the wherein one digit number with the terminal system time
Word is identical.If the number of the data encryption key of user's input is identical as the wherein one-bit digital of terminal system time, by user
The data encryption key of the digital corresponding position of the data encryption key of input is set as wherein one with the terminal system time
Associated dynamic digital key.
Exemplary with reference to aforesaid way two, when user is in the second word bit input number 2 of Password Input frame, and terminal is worked as
Preceding system time is 16:20, then the minute of the number 2 inputted and terminal present system time, previous bit value 2 was consistent, then may be used
To set dynamic digital key for the second of the data encryption key, i.e. the second word bit of Password Input frame is dynamic digital
Key.
Certainly, when the number of the data encryption key of user's input is identical as the wherein one-bit digital of terminal system time
When, may not be directly by user input data encryption key digital corresponding position data encryption key be set as with
The wherein associated dynamic digital key of terminal system time, but first inquiry user will use further according to user instruction
The data encryption key of the digital corresponding position of the data encryption key of family input is set as wherein one with the terminal system time
The associated dynamic digital key in position.That is: if the number of the data encryption key of user's input and terminal system time are wherein
One-bit digital is identical, asks the user whether to want that the digital encryption of the digital corresponding position for the data encryption key for inputting user is close
Key is set as the wherein associated dynamic digital key with the system time of terminal；If user's selection is, by user
The data encryption key of the digital corresponding position of the data encryption key of input is set as wherein one with the system time of terminal

For example, when user is in a certain word bit input number 2 of Password Input frame, and present terminal system time is 16:20,
The number then inputted is consistent with minute previous bit value, then can ask the user whether to want to set dynamic digital for the word bit
Key, if being switched to dynamic digital key set interface then to select corresponding dynamic digital key.
Step S122: dynamic number is generated according to the wherein one-bit digital of terminal system time and preset digital prediction algorithm
Word key.Terminal selected according to user instructions at least one of data encryption key for dynamic digital key after, then terminal
It determines that who digital correlation of the dynamic digital password and the terminal system time join according to user instructions, and then determines a kind of
Preset digital prediction algorithm is as the incidence relation between the dynamic digital password and the bit digital of the terminal system time.
It is exemplary, determine the process of who digital correlation connection of the dynamic digital password and the terminal system time such as
Under: assuming that present terminal system time be 16 when, 20 points.Therefore, in the present system time information of the terminal, there is numerical value
Temporal information 2 groups of temporal informations such as (h), point (m) sometimes, (h), point (m) are selected for user when can provide.It should be noted that
, above-mentioned every group of temporal information at least all comprising double figures value (such as minute include 2 and 0 double figures value, hour include 1 and 6
Double figures value), so can also by when (h), point (m) continue to segment, such as will by when (h) be divided into h1, h2, respectively correspond 16
When in 1,6；Point (m) is divided into m1, m2, respectively corresponds 2,0 in 20 points.Please refer to Fig. 2 B, it is shown that h1, h2, m1, m2 are supplied
User's selection, terminal selects the m1 of terminal system time, the i.e. tens of minute according to user instructions, it is determined that the dynamic number
Word password is associated with the tens of the minute of the terminal system time.
For another example, it is assumed that present terminal system time be 16 when, 20 points.Therefore, believe in the present system time of the terminal
In breath, 2 groups of temporal informations, every group of temporal information such as (h), point (m) all include double figures value to the temporal information with numerical value sometimes
(such as minute includes 2 and 0 double figures value, and hour includes 1 and 6 double figures values), so can also by when (h), point (m) continue it is thin
Point, for example, by when (h) be divided into h1, h2, when respectively corresponding 16 in 1,6；Point (m) is divided into m1, m2, is respectively corresponded in 20 points
2,0.It is exemplary, it is assumed that the second-order digit of the digital encryption secret key of user's input is 2, then terminal determines number 2 and terminal
The m1 bit digital of present system time is identical, then present system time in the second-order digit of the digital encryption secret key and terminal
M1 bit digital is associated.
It is exemplary, determine the preset digital prediction algorithm of one kind as the dynamic digital password and the terminal system time
Incidence relation between the bit digital can pass through following two implementation:
Implementation one: after determining the dynamic digital password and who digital correlation connection of the terminal system time, then
There is provided at least one preset digital prediction algorithm for selection by the user.Preset digital prediction algorithm is simple function, should
Function includes simple addition, subtraction, multiplication, and simple addition, subtraction, multiplication can reduce the difficulty in computation of user, can be with
User is allowed to be quickly obtained the dynamic digital cryptographic keys according to the present system time of terminal, it is subsequent to facilitate user to carry out
Decryption oprerations.It is exemplary, such as Fig. 2 C so, with additive and for subtraction, can provide simple function i-1, i, i+1, i+2 to
User's selection, the wherein one-bit digital in terminal system temporal information that wherein i has been selected for user, is only to lift herein certainly
Example explanation, does not represent the preset digital prediction algorithm of the embodiment of the present invention and is confined to this.With reference to shown in Fig. 2 C, user is selected
Function i+1.
Implementation two: after determining the dynamic digital password and who digital correlation connection of the terminal system time, directly
It connects using the bit digital of terminal system time as the dynamic digital password, i.e. the dynamic digital password and terminal system time
Incidence relation between the bit digital is relation of equality.
For example, present terminal system time be 16 when, 20 points.With reference to Fig. 2 B, it is shown that h1, h2, m1, m2 are selected for user
Select, terminal selects the m1 of terminal system time according to user instructions, i.e., the tens of minute as with the data encryption key
Third position key.At this point, user specifies m1 directly as the dynamic digital key of the data encryption key.
Further, during determining digital decrypted key, according to wherein one and the number of terminal system time
The calculated result (dynamic digital key) that prediction algorithm obtains may not be a position, can only take to calculated result at this time a
Position.That is: operation result is generated according to the wherein one-bit digital of terminal system time and preset digital prediction algorithm, then with fortune
The numerical value of result position is calculated as the dynamic digital key.It is exemplary, if the digital decrypted key prestored be 9,8, m2+1,6,
M2 is the latter bit value 9 of minute numerical value 49, and the corresponding function of digital prediction algorithm is m2+1, then the calculated result of function is
10, password of a position 0 of calculated result as the word bit is only taken at this time, i.e. current password is 9,8,0,6.
Step S123: terminal receives the static number key in data encryption key.The static number key is number.
For each word bit of Password Input frame, user may be static number key in word bit input, can also
Can select dynamic digital key.It, can be in general, after whole word bits of Password Input frame are all inputted or selected by user
Terminal issues determine instruction, such as clicks " determination " key to complete the determination of password setting.Terminal is receiving determine instruction
Afterwards, the digital encryption for just receiving the static number key in the data encryption key of each word bit user input or user setting is close
Dynamic digital key in key.
Therefore, terminal both can first receive the static number key in data encryption key, can also first receive number and add
Dynamic digital key in key, can also be while receiving, i.e. step S122 and step S123 can be interchanged or side by side.
Step S124: terminal generates data encryption key according to the dynamic digital key and the static number key.Such as
User setting password (i.e. data encryption key) 9,8, m1+1,6, with reference to shown in Fig. 2 D and Fig. 2 E, wherein 9,8,6 three are quiet
State digital cipher, if it is exactly m1 that user, which has selected above-mentioned m1 and function i+1, i, dynamic digital key is m1+1.After
Input password decryption when, m1 by become input password when minute numerical value previous bit value.Assuming that user 49 divides at 21
Password decryption is inputted, then the previous bit value 4 that m1 is 49 at this time, the corresponding code characters of the word bit are 4+1=5, i.e. user exists
Need to be only in word bit input 5 correct matched when input password decryption, i.e. four word bits are respectively 9,8,5,6 to be only
Match.
Step S130: terminal is encrypted terminal using the data encryption key.
Terminal is according to each word bit user static number key inputted or the dynamic digital key and word bit of user's selection
Sequence determines data encryption key and stores.Terminal receives static number key or the user selection of each word bit user input
The dynamic digital that the static number key inputted after dynamic digital key according to user corresponding to each word bit or user select
Key forms whole data encryption key.
Figure 1B is another terminal encryption method flow diagram provided in an embodiment of the present invention.In the present embodiment, including step
Rapid S110~step S150, step S110~step S130 are consistent with the description of above-described embodiment.The difference is that in step
After S130, further comprise the steps of:
Step S140: terminal receives the digital decrypted key of user's input, judges the digital decrypted key and digital encryption
Whether key is consistent；Wherein, which includes at least a dynamic digital key, the dynamic digital key and terminal
System time wherein one it is associated.
Terminal can provide the Password Input frame with multiple word bits, for user inputs character namely password.User is defeated
After complete, when detecting the determine instruction of user, the character of multiple word bits of user's input is received.
It is exemplary, it is assumed that there are four word bits for Password Input frame tool, i.e. password is four.User can be each in four word bits
Inputting a number, totally four numbers are as digital decrypted key, such as the digital decrypted key of user's input is 9,8,7,6.Eventually
After end receives the digital decrypted key of user's input, judge whether digital decrypted key is consistent with data encryption key.
Terminal determines that the process of Contemporary Digital encryption key specifically can be with reference to the step in above-mentioned terminal encryption method
S122.I.e. according to wherein one (such as m1 of the user's selection among the above) number of terminal system time and preset digital budget
Algorithm determines current dynamic digital key；Determine that Contemporary Digital encryption is close further according to static number key and dynamic digital key
Key.
For example, if present system time 49 divides when being 21, that is, get present system time information when being 21,49 points.
If the data encryption key prestored is 9,8, m1+1,6, Contemporary Digital encryption key is 9,8,5,6.
During determining digital decrypted key, obtained according to wherein one and the digital prediction algorithm of terminal system time
Calculated result (dynamic digital key) may be it is double-digit, position can be only taken to calculated result at this time.That is: according to
The wherein one-bit digital of terminal system time and preset digital prediction algorithm generate operation result, then with operation result position
Numerical value as the dynamic digital key.Such as if the digital decrypted key prestored is 9,8, m2+1,6, m2 be minute numerical value
49 latter bit value 9, the corresponding function of digital prediction algorithm are m2+1, then the calculated result of function is 10, only take meter at this time
Password of a position 0 of result as the word bit is calculated, i.e. current password is 9,8,0,6.
After terminal has determined data encryption key (current password), judge whether are digital decrypted key and data encryption key
Unanimously, that is, step S150 is executed.
Step S150: if the digital decrypted key is consistent with the data encryption key, decryption processing is executed to terminal.
Specifically, if it is determined that user input digital decrypted key and data encryption key (current password) unanimously,
The digital decrypted key for then illustrating user's input is that correctly, the terminal is decrypted at this time.If it is determined that arriving user
At least one in the digital decrypted key of input is inconsistent with data encryption key, then password authentification fails, not to the terminal
It is decrypted.
It is exemplary, user setting password (i.e. data encryption key) 9, m2+1,8,6, wherein 9,8,6 three are static number
