PEMECAHAN SANDI KRIPTOGRAFI DENGAN MENGGABUNGKAN METODE HILL CIPHER DAN METODE CAESAR CIPHER

Abstract

The development of modern technology resulted in the confidentiality of a message not guaranteed security. While most messaging users have not yet understood the software. Based on this then the author will examine the traditional cryptographic password for easy understood by the user of the message. In this paper the message is a cryptographic password by combining Hill Cipher and Caesar Cipher methods. In the operation of cryptographic encryption and decryption, the steps used are the Caesar cipher method, while in the steps use the key by using Hill Cipher method. In making or decoding the password only the message maker and the message recipient are aware of how the operation technique works. Thus it is expected that the delivery of confidential messages is guaranteed security.
