Abstract

Many people want their data unknown to others. To maintain the security and confidentiality of a data, one can apply the cryptographic algorithm. Although many cryptographic algorithms exist today, many have been solved by cryptanalysis. To improve the security of a text data, can by adding with the compression algorithm. Although the cryptographic algorithm used is a classical cryptographic algorithm, if added to the compression algorithm it will complicate cryptanalysis to find the original data. This research is done by applying a columnar transposition algorithm which is a simple classical cryptography algorithm, with Fibonacci Codes Algorithm to compress data. The results obtained are more secure data security than using the modern cryptographic algorithm, because the character results from the encryption process changed again after the encoding process and the number of characters ciphertext fewer than the number of plaintext characters.
