摘要： The present invention relates to a system (10) operable to control access to different physical spaces, each provided with an electrical locking device (121, . . . , 12n), with the aid of a programmable, mobile unit (14). The system (10) comprises an authority means (16) operable to issue access rights connected to the programmable, mobile unit (14) in the form of an authorizing data (AD), which authorizing data (AD) is sent to an authorization means (18) connected to the authority means (16), and operable to generate an alpha-numerical key for the mobile unit (14), and to send the alpha-numerical key and a unique identifier of the mobile unit (14) to an operator (20), which is connected to the authorization means (18). The operator (20) is operable to send the alpha-numerical key to the mobile unit (14) identified by the unique identifier. An electrical locking device (12i), wherein 1≦i≦n, and the mobile unit (14) uses an authentication protocol with the alpha-numerical key to authenticate the mobile unit (14), wherein the mobile unit, if it has been authenticated, sends the authorizing data (AD) to the electrical locking device (12i), and if the authorizing data (AD) comprises an identifier of the electrical locking device (12i), the mobile unit (14) is able to open the electrical locking device (12i) with the aid of a communication means (22) comprised in the mobile unit (14) for communication in the near field.

摘要： Methods (500) of a network node (111) for creating and joining secure sessions for members (111-114) of a group of network nodes are provided. The methods comprise receiving an identity certificate and an assertion for the network node as well as a secret group key for the group. The method for creating a session further comprises creating (501) a session identifier and a secret session key for the session, and sending (502) an encrypted and authenticated broadcast message comprising the session identifier. The method for joining a session further comprises sending an encrypted and authenticated discovery message comprising the identity certificate and the assertion, and receiving an encrypted and authenticated discovery response message from another network node which is a member of the group. The disclosed combined symmetric key and public key scheme is based on the availability of three credentials at each node, i.e., the identity certificate, the assertion, and the secret group key, which are received from a trusted entity. Further, a computer program, a computer program product, and a network node are provided.
摘要翻译：提供了用于创建和加入一组网络节点的成员（111-114）的安全会话的网络节点（111）的方法（500）。这些方法包括接收身份证书和网络节点的断言以及该组的秘密组密钥。用于创建会话的方法还包括：创建（501）该会话的会话标识符和秘密会话密钥，以及发送（502）包括会话标识符的加密和认证的广播消息。用于加入会话的方法还包括发送包括身份证书和断言的加密和认证的发现消息，以及从作为该组的成员的另一个网络节点接收加密和认证的发现响应消息。所公开的组合对称密钥和公钥方案基于从可信实体接收的每个节点上的三个凭证的可用性，即身份证书，断言和秘密组密钥。此外，提供了计算机程序，计算机程序产品和网络节点。
