A New Public Key Dynamic Signcrypted Identification (PK-DS-ID) Protocol Using Smart Cards

Secure civilian and military identification protocols are very important and useful cryptographic tool. In computer network security, the secure personal identification protocol is an interactive proof system; the prover and the verifier exchange multiple messages dependent on random numbers which they keep secret. In military aircraft identification friend or foe (IFF) systems, the aircraft can identify itself to the ground station using challenge-response identification protocol in real time process to distinguish friendly from hostile aircraft. In this paper, a new public key dynamic signcrypted identification protocol using smart card (PK-DS-ID) based on the intractability of the discrete logarithm problem has been proposed. The PK-DS-ID protocol uses the secure hash dynamic structure algorithm (SHDSA). PK-DS-ID has efficient computation time and communication overhead which satisfy the real time process. For the minimum security parameters recommended for use in current practice, the numerical value for the saving in communication overhead is 56% over Schnorr identification and 65% over Okamoto identification which are the recent most attractive practical identification schemes. The present scheme is designed to resist the advanced identification attacks by using Random Challenges and Timestamps techniques. The proposed scheme uses the Advanced Encryption Standard algorithm (AES) which satisfies today´s security, speed and memory requirements. PK-DS-ID scheme has an efficient computation time due to the saving in communication overhead which satisfies the real time process and it is designed to resist the advanced identification attacks using random challenges and timestamps techniques.
