Figure 1, shows a remote digital key generating system (10) according to a embodiment of the present invention. It includes an encryptor (12) and a decryptor (14). It also includes two identical chaotic systems, preferred embodiments of which are described above: a first chaotic system (16) and a second chaotic system (18). In operation, the encryptor (12) applies an initialization code (20), to the first chaotic system (16). The first chaotic system is allowed to generate an unpredictable first key bitstream (22) of desired length. The first key bitstream can be used as a digital key to encrypt a plain text message according to any number of encryption algorithms known to those skilled in the art. The encryptor (12) also sends the initialization code (20) to the second chaotic system (18). The second chaotic system (18) is then allowed to generate a second key bitstream (24), which second key bitstream (24) will be identical to the first key bitstream (22). |
