Abstract: A device with key attestation features comprises an operating system stored in its memory, the operating system comprising a secure environment including a trusted application, and two or more device certificates, each associated with a device key pair, stored in the memory of the device. The trusted application is configured to handle key pair generation requests and key pair attestation requests to read an indication of a preferred device certificate. An attestation certificate that is generated in response to the key pair attestation request is then signed using one of the two or more device certificates with its associated device key pair based on the indication of a preferred device certificate.

Abstract: This application provides an extended authentication method and apparatus for a generic bootstrapping architecture and a storage medium. A first network element obtains a bootstrapping transaction identifier (B-TID) and a key lifetime; and the first network element sends the B-TID and the key lifetime to the terminal, so that the terminal performs extensible authentication protocol (EAP)-based generic bootstrapping architecture (GBA) authentication and key agreement (AKA) authentication with the first network element based on the B-TID and the key lifetime.

Abstract: In a method for secure provisioning of data to a client device, a non-trusted manufacturing facility is equipped with a secure server device to establish a secure data provisioning channel from the secure server device to trusted hardware in client devices without the secure server device and the client devices needing to have a shared secret.

Abstract: A user equipment in a communications system, the user equipment comprising: a memory arranged to store at least one identifier associated with the user equipment; a transceiver arranged to communicate with a node in the communication system, wherein the transceiver is arranged to receive the at least one identifier from the node in the communications system, wherein the at least one identifier is used by the user equipment to authenticate the user equipment to at least one further node in the communications system.

Abstract: An approach is provided for performing authentication in a communication system. In one embodiment, a key is established with a terminal in a communication network according to a key agreement protocol. The agreed key is tied to an authentication procedure to provide a security association that supports reuse of the key. A master key is generated based on the agreed key. In another embodiment, digest authentication is combined with key exchange parameters (e.g., Diffie-Hellman parameters) in the payload of the digest message, in which a key (e.g., SMEKEY or MN-AAA) is utilized as a password. In yet another embodiment, an authentication algorithm (e.g., Cellular Authentication and Voice Encryption (CAVE)) is employed with a key agreement protocol with conversion functions to support bootstrapping.

Abstract: A method and apparatus provide generic mechanism for a network application server. A receiver receives a request from a user equipment to provide authentication information to a network application function. A determining unit determines a key of a generic authentication architecture to integrate additional network application servers by extending an existing standard for user security settings. A providing unit provides the authentication information to the network application function.

Abstract: Systems, methods, and apparatuses are provided for facilitating authorization of a roaming mobile terminal. A method may include receiving a request for security key related policy information for a user equipment device. The request may be sent by a service providing node on a visited network. The method may further include causing a service authorization information request including a user security settings package to be sent to a policy decisioning server. The method may also include receiving, in response to the service authorization information request, a service authorization information answer including a modified user security settings package including the authorization policy information for the user equipment device. The method may additionally include causing the requested security key related policy information to be sent to the service providing node. Corresponding systems and apparatuses are also provided.

Abstract: Methods, a client entity, network entities, a system, and a computer program product perform authentication between a client entity and a network. The network includes at least a bootstrapping server function entity and a network application function entity. The client entity is not able to communicate with both of the network entities in a bidirectional manner. The 3GPP standard Ub reference point between the client entity and the bootstrapping server function entity is not utilized for authentication purposes, such as authentication using GAA functionality for unidirectional network connections.

Abstract: A method and arrangements for managing user data stored in a database of a communications system where the database is managed by a main controller is disclosed. In the method a user is first authenticated, where after an application entity can manage user data in the database that associates with the user and an application by communicating data between the application entity and a second entity connected to the communications system.

Abstract: An approach is provided for authenticating a mobile device. A mobile device initiates transmission of a request to an authentication platform for generating a public-key certificate to access a service from the mobile device. The mobile device receives an identity challenge and responds by initiating transmission of a tag specific to the mobile device to the authentication platform. The authentication platform uses the tag to generate a public-key certificate.

Abstract: This invention relates to security procedures in a communication system, specifically to production of key material. The invention provides a method for producing key material in a highly secure way for use in communication with a local network of a company. The method uses authentication information obtained from the communication system and information exchanged locally between a mobile station and the authentication systems of the company to produce a communication key for use in authentication procedures or e.g. for signing and/or encrypting data.

Abstract: An approach is provided for building a scalable service platform by initiating transmission of encrypted data from a public network cache. An access control server platform determines a first authorization key for a user and a second authorization key for a resource, and then encrypts the resource with the second authorization key, and encrypts the second authorization key with the first authorization key. The access control server platform initiates distribution of the encrypted second authorization key with the encrypted resource over a network. The access control server platform further initiates caching the encrypted second authorization key with the encrypted resource that meets a predefined threshold value (e.g., a data size, an access frequency, a modification frequency, or an auditing requirement) in a cache in the network, and initiates transmission of the cached and encrypted second authorization key with the cached and encrypted resource from the cache to at least one authorized entity.
