As Smart Device research processes, the needs of information security in light devices is increasing. For example, Zigbee provide Information Security by applying $AES-CCM^*$ defined IEEE 802.15.4 standard. However, according to information security law in Korea, only devices with KCMVP certification can be used in government organization and facilities. Therefore, this paper provide a solution to apply ARIA-CCM and ARIA-GCM for KCMVP in reserved field of IEEE 802.15.4 standard. For analyzing performance, we provide the speed test result of ARIA-CCM and ARIA-GCM comparing with $AES-CCM^*$.

This paper suggests a new scalar multiplication algerian to resist SPA which threatens the security of cryptographic primitive on the hardware recently, and discusses how to apply this algerian Our algorithm is better than other SPA countermeasure algorithms aspect to computational efficiency. Since known SPA countermeasure algorithms have dependency of computation. these are difficult to construct parallel architecture efficiently. To solve this problem our algorithm removes dependency and computes a multiplication and a squaring during inversion with parallel architecture in order to minimize loss of performance. We implement hardware logic with VHDL(VHSIC Hardware Description Language) to verify performance. Synthesis tool is Synplify Pro 7.0 and target chip is Xillinx VirtexE XCV2000EFGl156. Total equivalent gate is 60,508 and maximum frequency is 30Mhz. Our scalar multiplier can be applied to digital signature, encryption and decryption, key exchange, etc. It is applied to a embedded-micom it protects SPA and provides efficient computation.
