Summary: | A method of authenticating an originator of a packet in a network comprising filtering the packet for a tag embedded therein, reading the tag contents including an identifier and an encrypted hash, decrypting the encrypted hash included in the tag, calculating a second hash from the identifier of the originator, and authenticating the originator of the packet upon determining the decrypted hash and the calculated hash are identical is provided. A node for authenticating an originator of a packet comprising a processing unit, a memory unit operable to store an authentication algorithm therein, and an interface to a network medium operable to receive the packet, the authentication algorithm operable to filter the packet for a tag embedded therein, decrypt an encrypted hash in the embedded tag, calculate a hash from an identifier in the tag, and authenticate the originator upon a comparison between the decrypted hash and the calculated hash is provided. |
