摘要： A system and method for preventing unauthorized duplication of an identity module, IM, and authenticating valid IMs. Different information is stored in the IM and an authentication center, AuC, and if the information in the AuC is leaked, it is insufficient to clone the IM. The IM generates a first key, K1, and a second key, K2, while assuring that K1 cannot be derived from K2, and optionally that K2 cannot be derived from K1. The IM exports K2 and an identifier to the AuC while keeping K1 secret within the IM. During authentication, the IM provides to a third party such as a VLR, information containing the identifier. The VLR forwards the information to the AuC, which retrieves K2 based on the identifier and generates a first value, R, and a second value, X, based on at least K2. The AuC then returns R and X to the VLR, which forwards R to the IM. The IM then generates a response, RES, based on at least K1 and R, and sends the RES to the VLR. The VLR then verifies the RES based on X.

摘要： When a mobile terminal (10), having a basic identity module (12) operative according to a first security standard, initiates a service access, the home network (30) determines whether the mobile terminal has an executable program (14) configured to interact with the basic identity module for emulating an identity module according to the second security standard. If it is concluded that the mobile terminal has such an executable program, a security algorithm is executed at the home network (30) to provide security data according to the second security standard. At least part of these security data are then transferred, transparently to a visited network (20), to the mobile terminal (10). On the mobile terminal side, the executable program (14) is executed for emulating an identity module according to the second security standard using at least part of the transferred security data as input. Preferably, the first security standard corresponds to a 2G standard, basically the GSM standard and the second security standard at least in part corresponds to a 3G standard such as the UMTS standard, and/or the IP Multimedia Sub-system (IMS) standard.

摘要： A method and apparatus for key management in a communication network. A Key Management Terminal KMS Terminal Server (KMS) receives from a first device a request for a token associated with a user identity, the user identity being associated with a second device. The KMS then sends the requested token and a user key associated with the user to the first device. The KMS subsequently receives the token from the second device. A second device key is generated using the user key and a modifying parameter associated with the second device. The modifying parameter is available to the first device for generating the second device key. The second device key is then sent from the KMS to the second device. The second device key can be used by the second device to authenticate itself to the first device, or for the first device to secure communications to the second device.

摘要： Binary data representing a code word of an error-correcting code is used for calculating a syndrome, wherein a given portion of the binary data comprises k groups of data bits and represents a field element of the finite field GF(pk), p being an odd prime number, the field element comprising k coefficients in accordance with a polynomial basis representation, each group of data bits of the given portion representing a corresponding one of the k coefficients. The given portion is stored in a first general purpose register and is processed such that the k groups of data bits of the given portion are processed in parallel; determining whether the syndrome is equal to zero; and detecting and correcting errors in the binary data if the syndrome is not equal to zero.

摘要： A method of facilitating the lawful interception of an IP session between two or more terminals 12,13, wherein said session uses encryption to secure traffic. The method comprises storing a key allocated to at least one of said terminals 12,13 or to at least one of the subscribers using one of the terminals 12,13, at the terminal 12,13 and at a node 5,8 within a network 1,6 through which said session is conducted, or a node coupled to that network. Prior to the creation of said session, a seed value is exchanged between the terminal 12,13 at which the key is stored and said node 5,8. The key and the seed value are used at both the terminal 12,13 and the node 5,8 to generate a pre-master key. The pre-master key becomes known to each of the terminals 12,13 involved in the IP session and to the network node 5,8. The pre-master key is used, directly or indirectly, to encrypt and decrypt traffic associated with said IP session.

摘要： A method and apparatus to establish trust between two nodes in a communications network. A first node receives from a network node authentication data unique to the first node, which can be used to derive a compact representation of verification data for the first node. The first node also receives a certified compact representation of verification data of all nodes in the network. The first node derives trust information from the authentication data for the node, and sends to a second node a message that includes the trust information and part of the authentication data. The second node has its own copy of the certified compact representation of verification data of all nodes in the network, and verifies the authenticity of the message from the first node using the compact representation of verification data of all nodes in the network and the received trust information and authentication data.
