  • Patent number: 7190788
    Abstract: The methods and apparatus described herein encrypt an unencrypted binary string using an encryption key and a varying-radix conversion method. The encryption key is used to parse the unencrypted binary string into unencrypted sub-strings. The varying-radix conversion method is used to transform the unencrypted sub-strings into encrypted sub-strings. The encrypted sub-strings may then be concatenated together to produce an encrypted binary string. In addition, the reverse process is employed to recover the unencrypted binary string from the encrypted binary string. For example, the decryption process may occur after the encrypted binary string is transmitted over a network communications system.
