E-voting security system for the election of EEPIS BEM president

The Development of technological system have grown up rapidly including how to vote. In general, people are accustomed to vote by using ballot paper. In Indonesia, this way is considered ineffective both in terms of cost, time, and governance. Due to this, the creation of an electronic voting system or known as e-voting based on android for the voting system implemented can be performed more easily and effectively. It takes a short time, the cost is cheaper, and it can minimize errors. However, currently existing e-voting still has a weakness in terms of security that can allow a person manipulate the data of the voting result. Therefore, e-voting requires a security method that can guarantee the authenticity of the voting data. In this case the 1024-bit Shamir's algorithm is used for anonymity voter authentication. With the feature of anonymity of voters (secrecy of voter identity) so that achieved is one of the most important electoral principle is “Secret”. Moreover, it keeps the authenticity of data voting results used SHA-1 algorithm. From the test results, the average time for generating key by Shamir's algorithm is 552.8 milliseconds. The fastest average time for computation process comprises signing, transmission and validation time is 3747.1 milliseconds.
