In the age of explosive growth in information exchanges, there is indeed for message security. Data Encryption Standard (DES) is one of the symmetric encryption algorithms which kept the dominant position in the area of data encryption over the last few decades. Nowadays, with a rapid development in the field of computer, the security of DES is too low when encountering the brute-force method for decryption. Therefore, 3DES applies the DES encryption algorithm three times to each data block to strengthen the complexity of the cryptosystem. Nevertheless, due to the meet-in-the-middle attack, it reduces the effective security of the ciphertext. Many studies have shown that most of the existing methods are unreliable in the aspect of security. Accordingly, this study proposes a double encryption using the 3DES and chaotic synchronization to increase the strength of the encryption. A design methodology for Takagi-Sugeno (T-S) fuzzy model-based secure communication in multiple time-delay chaotic (MTDC) systems is presented. The proposed encryption method produces a more secure communications system, while effectively protecting the encrypted message.
