Abstract

REST is a web-based client-server communication architecture. REST server provides data in the form of URL to be accessed by client in JSON form. The disadvantage of current REST architecture is the lack of authentication mechanism which allows anyone to access, change, or delete data. To solve the authentication problem from REST architecture, is required an authentication system. JWT is a token that is proposed to authenticate and ensure message integrity. Using JWT on the REST architecture can provide authentication and security. In JWT Implementation there are various hash algorithms used, one of them is HMAC-SHA256 algorithm which is SHA256 algorithm using message authentication code (MAC). In 2011, the vulnerability of SHA256 is found which is preimage attack and pseudo collision attacks. BLAKE2S algorithm is an algorithm created in 2012 succeding BLAKE algorithm. BLAKE2S algorithm offers better security since it is built with HAIFA iteration and ChaCha stream cipher. This research implemented BLAKE2S algorithm on JWT for REST API service authentication mechanism as alternative HMAC-SHA256 algorithm. Test-vector is performed to ensure the test-vector given in RFC document. The Authentication process of BLAKE2S is 88.583 ms.

Abstract

In Indonesia, games have become a game that people love. Both from adults, teenagers, to children. Players in Indonesia have reached 43.7 million where 26% are people aged 21-35 years, then 21% of them are people aged 10 -20 years. If playing too long this can lead to a problem especially on their health. If they play the game for too long, then their eyes can feel sore, and otherwise can make headache caused by lack of room lighting. In addition to the problem of games there are also other problems, that problem is the resource they used. Therefore, there are systems that will provide notifications when gamers play unhealthy. Hopefully they can play in sufficient place of lighting, play within a safe distance from the monitor and prevent them from playing for too long. This system will be active continuously so it needs a lowpower method to suppress the use of resources, current, and the system can be active for as long as possible. The current that the system uses after testing is 3.8 mA in sleep state and when normally it's 169.9 mA. In addition to current testing, tested also how the level of accuracy of the sensor and obtained the accuracy of the distance sensor of 98.07% and then the accuracy of LDR sensor of 96.42%.
