Claim:
1. A method comprising: generating a feature character string when a first device receives a request to establish a communication from a second device including an indication of a second public key, wherein the first device is associated with a first public key and a first private key, and the second device is associated with the second public key and a second private key; using the second public key to encrypt the feature character string; publishing a first identification of the first device that is at least partly based on the encrypted feature character string; using the first private key to decrypt a second identification of the second device, wherein the second identification is configured and transmitted by the second device to include the feature character string generated by the first device and encrypted using the first public key of the first device; determining that the feature character string is obtained after using the first private key to decrypt the second identification of the second device; and establishing the communication between the first device and the second device.
