Abstract

Technology developments demanded cutting-edge data security systems, especially on hardware systems. NIST (National Institute of Standard Technology) is an institution that oversees data security standards. NIST organized an eSTREAM project to search for new stream cipher algorithms for various hardware and software application profiles. The algorithm chosen for hardware is the grain algorithm. Grain algorithm is superior because the architecture has a complex level of complexity so that the level of security is higher. The algorithm has two versions v1 and 128 bit. This research tells how to use grain algorithm to secure data on hardware side applied to arduino mega. Researchers chose arduino mega due to the use of this microcontroller in the IoT and there is no update data security using the latest stream cipher. Conducted 3 stages of testing that is validation test vector, performance analysis between grains through the execution time keystream and data encryption and decryption. This research yielded keystream validation in accordance with test vector. The results were analyzed using Independent t-test statistic test, with the result of Sig's keystream execution time. 0.662 then there is no significant difference in the performance of grain algorithm v1 and 128. While the results of the execution time of encryption and decryption of both algorithms also have no significant differences, indicating that arduino mega has a stable performance in running both algorithms.

Abstract

NIST (National Institute of Standard Technology) is the institution that regulates data security standards. NIST held a project called eSTREAM to update old outdated stream ciphers. The grain algorithm is selected as a security algorithm on the hardware side and replaces the previous stream cipher. Grain algorithm has 2 versions, 80 bit and 128 bit. Security at the hardware level is also required to keep information data. With the update of security standards from NIST, this research is conveying the idea to utilize the grain algorithm for data security that will be implemented in raspberry pi. This study chose raspberry pi due to the large use of this mini PC in the Internet of Things and there is no update data stream cipher security. Raspberry pi that has been implemented with grain will do 3 testing that is test of keystream validation with test vector, time of execution process of IV and Key to produce keystream and encryption and data decryption. The test of execution time, will be analyzed using Independent t test test, the result of testing of keystream execution time on grain v1 and 128 algorithm is -2,146 with probability (Sig.) 0,000 indicates a significant difference, as well as with execution time of 8, 12 and 16 bit encryption and decryption. This research concluded raspberry pi performance for both stable versions.
