Techniques for validating public keys using AAA services

Techniques for validating a first device are provided. A second device receives a first device public key and first device identification information from the first device. Validation of the first device identification information is required for a security process using a security protocol. The second device sends the first device public key and the first device identification information to an AAA server for validation. The AAA server is separate from the second device. The second device receives a response from the AAA server, the response including an indication whether the received first device identification information is validated with stored first device identification information for the first device public key. If the first device identification information is validated, an action for the security process is performed using the security protocol.
