摘要： The present invention relates to the interconnection between a local wireless network (100) and an external IP network (200) via a border router or gateway device (400). Given the difference between the two networks, it is recognized to be beneficial that long IP addresses may be readily translated to and from short local network addresses. An address converter comprised in the border router or gateway device (400) is disclosed to implement an efficient and dynamic mapping between the short local identifiers and the long IP addresses, which eliminates a large mapping table used by a convention approach. Two setups are disclosed related to the implementation of the address converter. One is based on a cipher/decipher function pair, and the other is based on a cryptographic hash function.

摘要： A system for secure data transfer using air gapping. A first module (100) comprises: a first module communication interface (102) configured to communicate with a public network; a first module controller (105) and a first module data interface (106) configured send and/or receive data from the public network. A second module (200) comprises: a first read-only memory (202) storing an operating system; a second module communication interface (208) configured to communicate with a secured machine or a secured network to transmit data from and to the second module; a microcontroller (205) and a second module data interface (206, 207) for communicating with a bridge module (300). The bridge module (300) comprises: a bridge module controller (305); a bridge module data interface (309) for communicating with the bridge module controller (305); memory (303) for storing data; a switch (310) configured to selectively connect the bridge module data interface (309) to either the first module data interface (106) or to the second module data interface (206, 207) such that the first module data interface (106) is never connected with the second module data interface (206, 207). The bridge module controller (305) is configured to receive data from the second module (200), store the data in the memory (303), and send the data to the first module (100) and/or to receive data from the first module (100), store the data in the memory (303), and send the data to the second module (200). The second module (200) further comprises a second read-only memory (203) storing sets of private keys of the second module (200) and at least one public key of another remote entity; a cryptographic unit (209) configured to encrypt and/or decrypt data using the keys stored in the second read-only memory (203).

摘要： A computer implemented method of providing identification to one of many online services, and a system comprises an interface system and an identifier manager. The interface system is configured to provide a secret identifier to a requesting one of the online services in a session. The secret identifier is received from the identifier manager. The secret identifier is stored in the identifier manager. The session in which the secret identifier is provided to the online service is identified by a session identifier provided from the online service to a device which the online service is to be provided. The session identifier is then provided to the identifier manager. The session identifier is then provided to the interface system. The session identifier is then provided to the online service so that interactions are allocated to the session.

摘要： A system supporting a networked database service includes a controller configured to receive one or more data request and authenticate the one or more data request. A gateway (GW) in communication with the controller, is configured to receive at least one of the one or more data request from the controller, perform data classification on data received in the request, and generate a cryptographic key based on the data classification, a hardware-protected key of the GW, and a second (encryption) key. The cryptographic key is for accessing a database. The controller and the GW are operated by different parties.
