Distributed.net collaborated with the electronic frontier foundation to break a Data Encryption Standard (DES) key, spending 22 hours and 15 minutes, and implying that the DES is no longer a secure encryption method. In this paper, the authors propose a more secure one, called the True Random Number Encryption Method (TRNEM), which employs current time, true random numbers and system security codes as parameters of the encryption process to increase the security level of a system. The same plaintext file encrypted by the TRNEM at different time points generates different cipher text files.
