Abstract
Methods and systems for encrypting data are disclosed. A circuit uses a white noise generator to capture a random string of bits as an encryption key. The encryption key is generated at a central server and is provided to a subscriber on a physical memory device. The subscriber uses the encryption key to encrypt a source data file. The encrypted data file is sent to the central server, which uses the encryption key to decrypt the encrypted data file and to recover the source data file. The file name for the source data file may be encrypted into the encrypted data file and a new name assigned to the encrypted data file. A random number index may be used to identify the starting point of the encrypted file.
