The realization flow figure of the intelligent cipher management system that provides for the embodiment of the invention shown in Figure 4.Wherein mainly be concrete function and the realization that specifies its each functional module that comprises from intelligent cipher management system side.Concrete implementation procedure specifies as follows:
In step 401, need to judge whether encryption lock, then connect the encrypted code lock if desired, if encryption lock is incorrect, then show to connect prompting; If encryption lock is correct, then change step 402 over to.Here need to prove that this step is an optional step, if the user will advise using encryption lock for the security ststem of strengthening client.If system needs the user to use encryption lock, then the user is must be connected to encryption lock on the computer of client when remote server connects.If encryption lock connects correctly then continues step 402, otherwise being connected of client and remote server will be refused/cancelled in system.
In step 402, start client and be connected with the long-range of remote server.
In step 403, judge whether success of long-range connection, if success then change step 404 over to, otherwise timing in one embodiment, surpasses 120 seconds when the time of accumulative total, then shows the prompting that can't connect, otherwise continue the judgement of step 403.Here need to prove; Because intelligent cipher adopts client to intercom mutually with the remote server end and realizes; So client must guarantee real-time man-to-man the connection with the remote server end; If client and server end are owing to the disconnection of long-time (acquiescence is more than 120 seconds) appears in the reason of network, system will point out the user to obtain with remote server to be connected.The reason that appearance can't be connected to server has a lot, but the relevant suggestion that solves can be pointed out by system, such as the inspection network whether connect unobstructed, whether be a plurality of IP, encryption lock whether correct, connect whether overtime etc.
In step 404, launch SESSION (session), launch digital certificate and launch login daily record etc.Here need to prove that SESSION mechanism is a kind of mechanism of server end, server uses a kind of structure that is similar to hash table to come preservation information.When program need be created a SESSION for the request of certain client; Server at first checks whether comprised a SESSION sign (being called SESSION_ID) in the request of this client, and if comprised a SESSION_ID before would explaining for this reason client created SESSION.SESSION is powerful guarantee, especially some session variables help of too busy to get away SESSION especially that realizes client and server end continuous communiction, so SESSION promptly opens in system in that time that client and server are set up communication.
In addition, digital certificate is to guarantee the subscription client login and carry out the data information transfer safety operation and be used for the disk tools of authentication.Through issuing the identity audit of the strictness before the digital certificate; Guarantee the holder's of digital certificate legal capacity; Thereby the holder of digital certificate to digital certificate contract, order, bidding documents, etc. the signature done in electronic document or the system bear legal liabilities, guarantee the legal force of electronic operation.Digital certificate is used for the mutual confirmation of enterprise identity authentication, data transmission security guarantee and business operation, has the legal effect of digital signature, to ensure networking user's information security and intelligent cipher management system safety.
In addition, the main effect of login daily record is to be used for the recording user relevant information in when login, and these information comprise time that the user logins, IP address, prompt, password, errors number, relaying time, disengaging time etc.The intelligent cipher management system will regularly be carried out back-up processing to these daily records, reduces server expenses on the one hand, on the one hand as carrying out safety backup.
In step 405, the client and server end begins communication.
In step 406, judge whether this user logined, if do not login, then change step 407 over to, otherwise judge whether that success withdraws from, if then get into step 407, otherwise go to step 415.Here need to prove that the intelligent cipher management system can at first be carried out this user's SESSION checking being connected once more of client and server.If this user's SESSION state is for logining, intelligent cipher will be opened this user's corresponding authority automatically.Otherwise intelligent cipher will be opened the account input page.The account input page is generally as shown in Figure 7.The account inputting interface can be used for importing the title of account.
In step 407, the explicit user login interface, the user is according to the prompting input account information at interface.
In step 408, system judges according to the information of user input whether this user exists, if existence then continue step 409, otherwise would change step 416 over to.Here need to prove the user authentication technology that the intelligent cipher management system adopts client to combine with server.At first can verify the account of user's input, if illegal will not the submission in client.After account was submitted to server, server can carry out corresponding safe handling to account and inject so that prevent script.Intelligent cipher will be opened database and inquire about this user subsequently, if this user does not exist system will point out the user---and " this user does not exist ".If there is this user in the database, the intelligent cipher management system will get into password input flow process automatically.
In step 409, generate SESSION prompt at random.Prompt is the key of intelligent cipher at random, because the user need carry out mental arithmetic to the known algorithm of these prompt utilizations.Because the prompt at random after landing is all inequality at every turn, so each calculated result is also all different.The intelligent cipher management system realizes so-called dynamic password through the mode that prompt at random adds user's mental arithmetic.Moreover, for the purpose of more safely, the intelligent cipher management system can also be the form and the regularly renewal (giving tacit consent to 10 minutes) of prompt generation picture at random.
In step 410, the display password inputting interface supplies the user to calculate correct password at heart according to prompt and the algorithm that presets, and input.Interface for password input is as shown in Figure 6, can find out that itself and traditional password input frame are different, many two row prompts above the password input frame of intelligent cipher management system.This two row prompt is that the intelligent cipher management system generates at server end at random.Prompt at random among Fig. 5 has two row, but also is digital.The kind of prompt has much at random in fact, can be numeral, letter, figure, sound and the time and date of multirow.
In step 411, whether the password of system judges input is legal, do not import once more if conform to rule prompting user, if legal then continue step 412.
In step 412, system searches the algorithm that this user presets automatically.
In step 413, the algorithm result of calculation that system's utilization is found.
In step 414, system compares the password of automatic result calculated and user's input.
In step 415, if the server end result calculated equates that with the password of client input just expression is logined successfully, otherwise prompting user cipher mistake and misregistration number of times, and return step 410, let the user re-enter correct password.In one embodiment, when count value surpasses threshold value, for example threshold value is 3, then locks this user's account.The method that locks an account can have a variety of, and modal is definite time limit release (being that account is locked automatic unlocking after a period of time).But the intelligent cipher management system is also recommended other a kind of release mode, i.e. twice unlock password method.In other words as long as the correct password of the double input of user just can automatic unlocking.
In step 416,, then register new user if the user does not exist.
In step 417, system shows new user's register interface.
In step 418, the system prompt user is provided with user name.
In step 419, the system prompt user is provided with the algorithm of password.
In step 420, whether the systems inspection password compliant, if meet then continue step 421, resets otherwise get back to step 417 prompting user.
In step 421, system adds new user.
In step 422, the algorithm that system is provided with the user is carried out reversible encryption and is handled.
In step 423, system adds the algorithm of password.
In step 424, the algorithm that the storage user of system is provided with.
In addition, can also in step 425, get into other management functions.
In step 426, explicit user can be revised password.
In step 427, the user imports password under the prompting of system.
In step 428, system verifies the password of user's input.
In step 429, system's display password is revised the interface.
In step 430, the user is provided with the algorithm of new password.
In step 431, system carries out password test.
In step 432, encrypt the algorithm of new password.
In step 433, the algorithm of system update password goes to step 424 then.
Intelligent cipher management system use flow chart for providing shown in Figure 5 according to the embodiment of the invention.Wherein mainly specify the realization of intelligent cipher function from user side.Concrete use specifies as follows:
In step 501, the user imports account information;
In step 502, its legitimacy is judged according to the accounts information of user input by system, if legal then continue step 503, otherwise point out illegal account, return step 501 prompting user and re-enter account information;
In step 503, the system queries account;
In step 504, system judges whether the account exist, if account does not exist, then returns step 501 prompting user and re-enters account information; If account exists, then continue step 505;
In step 505, but the prompt of the automated randomized generation computing of system;
In step 506, the user inputs corresponding password according to prompt;
In step 507, whether the password of system judges input is correct, if correctly then verify successfully, otherwise points out user cipher mistake and misregistration number of times, and returns step 506, lets the user re-enter password.When the number of times of misregistration surpasses three times, lock this user's account.
