Abstract: The disclosure discloses a first server determining an encrypted authentication packet including (i) a crypted code field that indicates a type of the encryption authentication packet, (ii) a crypted payload field that includes an encrypted initial authentication packet, determined by utilizing a nonce, an encryption key, and an encryption algorithm, and (iii) a data length field that indicates a length of the encrypted authentication packet, the length including a sum of a length of the crypted code field, a length of the crypted payload field, and a length of the data length field. The method may also include transmitting, by the first server to a second server, the encrypted authentication packet to enable the first server and the second server to conduct an authentication process. Various other aspects are contemplated.
