The invention discloses an electronic access control system of a dynamic bar code. The electronic access control system comprises a mobile terminal, a service logic module, a bar code module and an access control module. According to the electronic access control system, a user registers and binds the terminal on a system, and when the user needs to access an entrance guard, the user applies for the permission of the entrance guard; the system generates a dynamic password, distributes the permission, and codes the dynamic password to the bar code after encrypting the dynamic password, pushes the dynamic password to a user terminal, and synchronizes the dynamic password to an access controller; the user scans the bar code on the access control system after acquiring the bar code, and the access control system scans the bar code to obtain the content included in the bar code and decrypts the content to obtain a password to judge whether a door is opened or not. The electronic access control system dynamically generates the bar code including password information and issues the bar code to the terminal user, thereby providing a convenient and rapid electronic entrance guard access method based on the dynamic bar code.

This invention provides a method for transferring third party landing based on IP network including: a door network station carries a ciphered KEY generated randomly by a service server to send a link request to a third party network station so as to avoid transmission of user ciphered codes and ensure absolute security of user codes, besides, since the third party network station calls back the Web server by copying the ciphered KEY to verify the cryptographic key so as to secure the absolute safety of shaking hands, since the door network station does not transfer user ciphered codes with the third party network station, which is not necessary to synchronize with the door station about codes, thus the requirement of complicated maintenance to synchronization on ciphered codes to the third party is reduced. This invention also provides a system for authenticating the transfer of third party landing based on the IP network and the third party network station and service servers.

The present invention provides a method for encrypting data for transmission over a wireless link. The method includes encrypting at least one block of data, at an air-interface application layer, using an encryption algorithm that receives a cryptosynch as input. The value of the cryptosynch is based on an order of the at least one block of data relative to other blocks of data. The value of the cryptosynch is recoverable by a receiver based on the ordering of the ordering of the blocks of data. The at least one encrypted block of data is transmitted to a receiver that is operable to preserve the order of the at least one block of data relative to the other blocks of data.

A mechanism that synchronizes passwords maintained for plural domains. A user maintains accounts in two domains. The first and second domains each maintain tables correlating userIDs with passwords, such that the same user's password can be different in the different domains. A database stores tables that correlate a given user's userID/password combination in the first domain with his corresponding userID/password combination in the second domain. The database is used to sign the user onto one domain when the user is working in the other domain. When the user changes his password in the first domain, the change is reported to the database, so that the database stores the current password. Optionally, the password change may be reported to the second domain, such that the user will have the same password in both domains.

Systems and methods are disclosed for enabling encryptor devices to provide real-time messages having offset cryptoperiods according to an offset algorithm within common crypto-sync pulse boundaries. A master clock aligns the encryptor devices to a common crypto-sync pulse. Subsequently, a cryptoperiod offset aligner assigns a different offset value according to an algorithm to each encrypted service. The corresponding encryptor device then begins the cryptoperiod, during which real-time messages are transmitted, at the assigned offset value from the common crypto-sync pulse.

A centralized password repository (CPR) provides network users with a password portal through which the user can manage password access to domains and applications on the network. A subset of the domains and applications on the network may be required, by design, to maintain a separate password infrastructure. For these systems, the CPR establishes a secure and authenticated communication channel and software on the system interfaces with the password infrastructure to synchronize the password in the system password infrastructure with the password in the CPR. For other systems not required to maintain a separate password infrastructure, the CPR performs password services by responding to requests from those systems seeking to validate user IDs and passwords. The CPR enables an administrator to modify network privileges and enables a user to alter passwords on the network through a single interface.

A method for reducing the number of times that a user must type his own login ID or password into various systems that require authentication is disclosed. The method comprises the steps of: 1. A user signs into his workstation, using a standard login ID and current network password. 2. A plugin program, inserted into the workstation operating system's login subsystem, captures the user's login ID and password. 3. In environments where this is either not technically possible or where insertion of such a plugin program is infeasible, once the user has completed the initial workstation login, a secondary login prompt is displayed, asking the user to re-enter his current network password. 4. A second operating system plugin program is launched, which monitors all user interface activity—keystrokes and pointer events representing user input, processes that are executed, and windows and data fields activated on the workstation's display(s). 5. The monitor plugin compares the values entered by the user into data fields to the login ID and password captured in step 2 or 3. Where a new match is found, identifying characteristics of the data field, such as window ID, window title, field ID, field name, field position within the window and process ID, are stored in a data file, an operating system configuration database, or some other database. 6. The monitor plugin compares the data fields displayed on the workstation to a list of already known data fields in storage. If a data field is displayed that matches one whose characteristics have already been captured in storage, the login ID or password that were intercepted in step 2 or step 3 are automatically inserted into that data field, as appropriate. The present invention provides a method for reduced signon, whereby the number of separate instances where a user must provide his own login credentials is reduced, possibly to a single set of ID/password per workstation login session. This method improves the level of service offered by an IT organization to its users, as it saves time and effort for those users.

According to the password management method, on one hand, excessive dependence on a network is avoided, and on the other hand, the server cannot directly modify the password or set the password. The potential safety hazard is avoided; password management is safe, reliable and flexible in use, and the dependence on a wireless network is reduced.
