    • In a wireless communications network including at least one authenticator (120; 1130; 1215) and at least one authentication server (140), wherein the authenticator is adapted to interact with the authentication server for authenticating supplicants (130a, 130b; 1130 ,1130a; 1230 ,1215) in order to conditionally grant thereto access to the wireless communications network, a short authentication method for authenticating a supplicant, the method comprising: providing a shared secret, shared by and available at the supplicant and the authentication server; having the supplicant provide to the authenticator an authentication token, wherein said authentication token is based on said shared secret available thereat; having the authenticator forward the authentication token to the authentication server; having the authentication server ascertain an authenticity of the received authentication token based on said shared secret available thereat; in case the authenticity of the authentication token is ascertained, having the authentication server generate a first authentication key based on said shared secret available thereat, and provide the generated authentication key to the authenticator; having the supplicant generate a second authentication key based on said shared secret; and having the supplicant and the authenticator exploit the generated first and the second keys for communicating with each other. The short authentication method is particularly useful in situations of handoff of the supplicant from an authenticator to another.
    • 在包括至少一个认证器(120; 1130; 1215)和至少一个认证服务器(140)的无线通信网络中,其中所述认证器适于与认证服务器交互以认证请求者(130a,130b; 1130,1130a; 1230,1215),以便有条件地授予对无线通信网络的访问,用于认证请求者的简短认证方法,所述方法包括:提供由所述请求者和所述认证服务器共享和可用的共享秘密; 使所述请求者向所述认证者提供认证令牌,其中所述认证令牌基于可在其上可用的所述共享秘密; 使认证者将认证令牌转发到认证服务器; 使所述认证服务器基于所述可用的所述共享秘密来确定所接收的认证令牌的真实性; 在确定认证令牌的真实性的情况下,使认证服务器基于在其上可用的所述共享秘密生成第一认证密钥,并将所生成的认证密钥提供给认证器; 使所述请求者基于所述共享密钥生成第二认证密钥; 并且让请求者和认证者利用生成的第一和第二密钥进行通信。 短认证方法在请求方从认证方切换到另一方的情况下特别有用。

    • In a communications network (100) including at least one authentication entity (140), adapted to authenticating a network access requestor (125) in order to conditionally grant thereto access to the communications network, wherein the authenticating is based on public key cryptography, a method for automatically provisioning the network access requestor with service acces credentials for accessing an on-line service offered by an on-line service provider (135) accessible through the communications network, the method comprising: during the authenticating the network access requestor, having the authentication entity request to the on-line service provider the generation of the service access credentials; at the on-line service provider, generating the service access credentials, encrypting the service access credentials by exploiting a public encryption key of the network access requestor and providing the encrypted service access credentials to the authentication entity; having the authentication entity cause the network access requestor to be provided with the encrypted service access credentials.
    • 在包括至少一个认证实体(140)的通信网络(100)中,适于认证网络接入请求者(125)以有条件地向其通知对通信网络的访问,其中所述认证基于公钥密码术, 用于使用服务访问请求者自动提供网络访问请求者的方法,用于访问由通信网络可访问的在线服务提供商(135)提供的在线服务,所述方法包括:在认证网络访问请求者期间,具有 认证实体请求到在线服务提供商生成服务访问凭证; 在在线服务提供商处,生成服务访问凭证,通过利用网络访问请求者的公共加密密钥加密服务访问凭证,并将加密的服务访问凭证提供给认证实体; 具有认证实体使得向网络访问请求者提供加密的服务访问凭证。
