Enkripsi dan Dekripsi Short Message Service Menggunakan Algoritma Caesar Chiper

Abstract

Delivery of SMS messages using an android-based message delivery method is still used. Messages sent to recipients should be safe without being manipulated, because it contains a secret message between sender and receiver.so it need the science of cryptography message that capable of maintaining the confidentiality of the messages of others. Encryption and description of the science of cryptography right to be patrolling the message, in order to secure from the threat manipulation messages. To make the process of encryption and description in use caesar cipher algorithm has advantages in the process of encryption and description, ie the number of characters to be encrypted will be equal to the character after encrypted. in addition, the encryption process and this description based on android. Android is a new technology at the present time that rule the world of mobile telephony worldwide. Android is an operating system that is open source so as to facilitate android application developers. With caesar cipher algorithm can be implemented with a secret message, both in the process of encryption and description. With this form of message encryption in the form monoalfabetik
