Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention will be made below further detailed Description.
The embodiment of the present invention provides a kind of cipher safe, and the safety box is connect with secure server communication, the guarantor Dangerous case includes processor, controller, electromagnetic lock, information-storing device, communicator, cabinet door, cabinet door, handle and buzzer；The cabinet Body is flexibly connected by hinge with cabinet door, and the electromagnetic lock is embedded in inside the frame of cabinet body, and the buzzer is embedded in cabinet door Outer surface on, the handle is fixed by screws on the frame of cabinet door.
The communicator, information-storing device, controller and buzzer are connected to the processor, and the controller is used for The opening and closing of the electromagnetic lock is controlled, the processor is communicated by the communicator with the security server to be led to Row password.
The cipher safe further includes control panel, and N row's PIN PAD, Mei Yipai are provided on the control panel PIN PAD can input a password, and the control panel is at best able to obtain N number of password, and the cipher safe passes through It is determined whether to enable the electromagnetic locks for the password and the relationship of the current password for comparing input.
In order to realize the use of the cipher safe, be also configured with multiple user terminals, the user terminal with it is described Secure server communication connection, the cipher safe, user terminal and the security server constitute a security system.
Security server described in the security system holds password for obtaining signcode and generating to divide, by the passage Password is transmitted to the cipher safe, holds password for point and is transmitted to user terminal, the user terminal is used for according to described point Hold password obtain input password, in order to user by it is described input password typing cipher safe control panel.
Specifically, the security server is configured before generating current password and point holding password, in configuration Appearance includes: to participate in opening password number α, minimum common unlatching password number β (β < α), core parameter value ξ and current password。
Wherein, it is described participate in opening password number α characterize need to generate point hold password number, each user terminal is only One point can be obtained and hold password.It is close that minimum common unlatching password number β characterizes input required for opening cipher safe The number of code.Core parameter value generates each point for server and holds password.
Specifically, it is as shown in Figure 1 to generate point method for holding password for server, comprising:
S101. parameter data set is determined according to the core parameter value ξ.
Specifically, the set of the ξ residue class of the supplemental characteristic set representations mould ξ.
S102. β -1 parameter a of random selection are concentrated in the supplemental characteristictConstruct algebraic expression
S103. α different parameter x are obtained at randomi, for each parameter xiIt carries it into the algebraic expression and obtains Corresponding value yi, that is, α parameter is generated to (xi,yi), wherein xiAnd yiDigit is respectively less than
S104. by parameter to (xi,yi) it is transmitted to user terminal as point holding password, each user terminal obtains one point Hold password.
Specifically, the method for the user terminal generation input password is as shown in Figure 2, comprising:
S201. it gets parms to (xi,yi)。
S202. according to parameter xiIt obtainsFirst serial data of position.
S203. according to parameter yiIt obtainsSecond serial data of position.
Specifically, xi, yiDigit less thanThen 0 is mended in low level.
S204. splice the first serial data and the second serial data obtains input password.
For each user terminal, it can show that input password is manually entered password in order to which user will input password and protects The control panel of dangerous case.
Specifically, the opening method of the safety box is as shown in Figure 3, comprising:
S301. β input password p is obtainedi, the length of each input password is M.
Specifically, the β input password arranges scrambler input by the N (N >=β) of control panel, and every row's scrambler is only It can one input password of typing.
S302. according to each input password pi, cipher mark is obtained to (xi,yi)。
Specifically, in the embodiment of the present invention password length be M, then beforeThe corresponding password x in positioni, afterPosition correspondence is close Code yi。
S303. it obtains with (xi,yi) it is 0 point using x as the first algebraic expression of independent variable.
Specifically, the algebraic expression can be expressed as
It S304. is the acquisition of the first algebraic expression of independent variable using x as the second algebraic expression of independent variable using x according to described, for The difference of the value of any x, corresponding second algebraic expression and the first algebraic expression is the multiple of core parameter value ξ.
S305. the constant term in second algebraic expression is obtained.
S306. judge whether the constant term is identical as current password.
Specifically, the current password is transmitted to password by cipher mode by security server in password setting link and protects Dangerous case, and stored by the information-storing device in the cipher safe.
S307. if they are the same, then electromagnetic lock is opened, otherwise, starts buzzer.
Specifically, the buzzer is built-in with timer, and the timer is used to after buzzer starts preset time close Close buzzer.
Further, it in order to promote the safety in cipher safe and security server interactive process, avoids passing through close The leakage of code, the embodiment of the present invention carry out whole encryption for the communication process of security server and cipher safe.
Security server is for current passwordCiphering process it is as shown in Figure 4, comprising:
S401. password for inquiry dictionary and obtain key set to be extracted from the password dictionary, the key set to be extracted with The current passwordThere is no same numbers；The each key length N of password dictionary is identical, the security server and password Safety box shares identical password dictionary.
S402. a key is randomly selected from the key set to be extracted as current key.
S403. the current password is countedThe middle highest number of the frequency of occurrences, and obtain the specific number of its appearance.
S404. the interference numeric string of preset length is generated, the interference numeric string has the characteristics that following: the interference number String includes all numbers in the current key, and only includes the number in the current key, and the interference number The frequency of occurrence of the minimum number of the frequency of occurrences is higher than current password in word stringThe middle highest number of the frequency of occurrences goes out occurrence Number.
S405. splice M current key and obtain key string, and will be described in each numerical order insertion in the key string Current passwordAmong obtain the first serial data.
S406. splice first serial data and the interference numeric string to obtain encryption data.
Correspondingly, cipher safe decryption method is as shown in Figure 5, comprising:
S501. the frequency of occurrences of number each in the data received is counted；
S502. the maximum N number of target number of the frequency of occurrences is extracted；
S503. key of the inquiry including N number of target number in password dictionary, obtains target cipher key；
S504. current password is extracted from the data received according to the target cipher key；
It S505. will current passwordIt is stored in information-storing device.
