KOMBINASI ALGORITMA RSA DAN ALGORITMA CIPHER TRANSPOSISI UNTUK KEAMANAN DATABASE

Abstract

Cryptography is a  solution or method of securing the  data  precisely  to preserve confidentiality and authenticity of data. It is also able to enhance the security aspects of a data or information. The aim of the  method is the  confidential  information  which is  sent  via  a network, can not be known or used by someone else. 
Cryptography  provides  two aspects of information security,  first  is  the protection of  the confidential data/information,  counterfeiting and  undesired  alteration  of  information. RSA algorithm is an asymmetric encryption algorithm, in other word this    algorithm uses the same key for both encryption and decryption process. Transposition cipher algorithm  encrypts  the plain text by removing small pieces of  the  message  around. By using a combination of the RSA algorithm and Transposition Cipher algorithm, it will be able to  improve the security of the data file storage in a database.

Keywords : RSA Algorithm, Transposition Cipher, cryptography.
