    摘要: A method and an apparatus are disclosed for securing authentication, authorization and accounting (AAA) protocol messages. An encryption key, a device identifier value, and verification data are received and stored at a network device. The verification data comprises in part a copy the encryption key and the device identifier value, and has been encrypted using a private key of a server. A shared secret is generated by applying a computational function to the encryption key and the device identifier value. Based on the shared secret, a first message integrity check value for a message is generated. The message, the first integrity check value, and the verification data are sent to the server. The server decrypts the verification data using the private key, extracts the encryption key and the device identifier value, and generates the same shared secret by applying the same computational function to the extracted encryption key and device identifier value. Based on this generated shared secret, a second message integrity check value is generated and compared to the received first message integrity check value.

    摘要: Various systems and method are disclosed for disseminating security server contact information in a network. For example, one method (e.g., performed by a security server) involves determining that a network device is a secure network device, in response to participating in a security exchange with the network device; and then sending a server list to the network device. The server list includes the network address of at least one security server. Another method (e.g., performed by a network device) involves initiating an authentication exchange; receiving a server list, which includes the network address of a security server, as part of the authentication exchange; and communicating with the security server by sending a packet to the network address included in the server list.

    摘要: A method of securely extending a protected network through secure relay of AAA information, when an isolated device lacks Layer 3 connectivity to an AAA infrastructure of the protected network, comprises receiving a first authentication message, from an isolated first network device, wherein the first authentication message is encapsulated in a first Layer 2 message, wherein the first authentication message seeks to authenticate a second network device using an authentication server, and wherein the second network device and the authentication server are within a protected network; extracting the first authentication message from the first Layer 2 message; forming a packet that includes the first authentication message; sending the packet with the extracted authentication message over a Layer 3 link to the authentication server, without modifying the extracted authentication message. Thus a network node within a protected network can relay AAA requests and responses between an isolated AAA client, encapsulated in Layer 2 messages, and an AAA server, in Layer 3 messages.
