Hopper Frequencies and Encryption

The usage of old technology in a new implementation.

Background

This article will look into the concept of using hopper frequency technology with encryption to enable more secure transport of information.

As a means to secure radio transmissions, frequency hopping technology using predetermined pseudo-random sequences has already been developed. Adapting this technology in conjunction with normal encryption will serve as a rock solid and secure method of sending and receiving sensitive information between computers.

Requirements

No specific system requirements.

Conceptual Design

The following diagram illustrates the subsystems and relation to each other, with an explanation below.

Explanation

Firstly a GUI is needed to view encrypted and decrypted data, with the necessary precautions against the persistence of the sensitive information, and application settings. A cryptology component, perhaps from a third party will be responsible for the transformation from plaintext to crypt text.

The crypt text should be divided in parts, and the parts sent in random order over random ports to the recipient.

The random number generator will determine the sequence of ports to use for the transportation of parts of the crypt text data, while the port manager will manage the port connectivity to the recipient of the data.

It is important to choose a set of ports to use for the transportation of data, and more importantly to constantly send data on all ports simultaneously. Since data transfer analysis over the ports may be transparent to an trained interested party, junk data should be sent on unused ports during the session.

The assumption is made that the junk data cannot be identified as such, and is similar in size and content to the crypt text.

Mathematics

On assumption that it will take time (T) to decrypt an intercepted encrypted message (see http://www.distributed.net/news.php ). And that your message is transferred to another computer in 10 parts (P). The attacker will have to determine the correct order of the data before a successful attempt can be made to decrypt the data. Therefore all possible combinations of the intercepted parts will have to be tried, including the junk data.

In the event that the junk data can be separated from the crypt text the time to decrypt the data without authorization would be T to the power of P.

Legal

There exist legal requirements that limit the usage of certain cryptology algorithms used by Microsoft operating system versions, to within the USA and Canada.

Conclusion

Combining a secure transportation method with the encryption of the data itself, makes the interception and decryption by unauthorized parties virtually impossible.
