PERANCANGAN APLIKASI PENGAMANAN INFORMASI TEKS DENGAN MENGGUNAKAN ALGORITMA KRIPTOGRAFI ALPHA-QWERTY REVERSE
qwerty reverse is one part of the classical cryptographic algorithm that serves
as the security of infor
mation by encoding to information. The process of encryption of that
information is encrypted and description. Alpha
qwerty reverse algorithm is a development of
vigenere cipher cryptographic algorithms. Alpha
qwerty reverse differences in terms of
of characters that are more than vigenere cipher in which the alpha
using 92 characters while vigenere cipher uses only 26 characters. Moreover, in terms of the
use of character is also different. In vigenere cipher, the characters used an a
either in the original message (plaintext), a key or an encrypted message (ciphertext) whereas
qwerty reverse using the alphabetical order of the plaintext and key keyboard.
Therefore, in this study will design a security applica
tion that is text information with the
cryptographic algorithm of alpha
qwerty reverse using a eclipse software. The aim of
designing applications, namely to secure the important text information contained in the
mobile phone based on android with the purp
ose of storing or transmitting through a mobile
phone communication service. From this study it can be concluded that alpha
cryptographic algorithms can be implemented on the text information security applications
designed and as the latest
cryptographic algorithms to secure the information by generating a
better level of security.
