A True Random-Number Encryption Method

In January, 1999, distributed.net and the Electronic Frontier Foundation collaborated with each other to break a DES key in 22 hours and 15 minutes, implying that the DES is no longer a secure encryption method. In this paper, we propose a more secure one, called the True Random Number Encryption Method (TRNEM for short), which employs true random numbers, the time parameters, and coated cipher text as the parameters of the encryption process to increase the security level of a system. After encryption, the cipher text is difficult to be cracked. We also analyze the security of the DES, AES and TRNEM, and explain why the TRNEM can effectively defend some specific attacks, and why it is safer than the DES and AES.
