Abstract

The login system is a process for accessing a computer by entering the identity of the user and the password to obtain permissions using the destination computer resources. In an information system security issues and maintaining data confidentiality is one important aspect. However, these security issues often get less attention from the owners and managers of information systems. If talking about security issues related to the use of computers, it is difficult to separate it with the login process. Login aims to provide security services on the system. In this research used ElGamal cryptography algorithm to secure username and password in web login. The security level of this algorithm is based on the problem of discrete logarithms in the multiplication group of prime modulo primes. This algorithm includes asymmetric cryptography algorithms that use two key types, namely public key and secret key. The data contained in the login is secured by using ElGamal algorithm, so the usernam e and password entered into the database are already in the form of ciphertext.
