Apparatus and method for a pseudo-random number generator for high precision numbers

DETAILED DESCRIPTION OF THE DRAWINGS The present invention is a random number generator for generating high precision numbers from a highly mobile platform, such as for example, a personal computer (PC) or like-type digital computer.
The invention is advantageously used to generate communications security (COMSEC) keys for data encryption in remote battlefield environments and other applications which require an easily transportable platform.
Referring to FIG.
1, there is shown a communications management system (CMS) 10, in conjunction with, the present invention random number generator is used.
The CMS system 10 enables the users of various field radio systems, for example, the SINCGARS (Export) family of ICOM Radios manufactured and distributed by the ITT Corporation, to manage security keys, frequencies, networks and other distribution assets from a Corps to Squad level.
The CMS 10 includes a base computer 12, such as for example, a DOS based IBM personal computer (PC) or like compatible PC, the computer being coupled to a printer 14.
The computer 10 has a bidirectional communications link 16 between FILL devices 18 and a unidirectional communications link 20 with the remote field radios 22.
The FILL devices 18 are essentially relay terminals and are adapted to receive and transmit information regarding the security keys, frequencies and other network data received from the base computer of the CMS system 10.
A bidirectional communications link 24 is also established between the field radios 22 and the FILL devices 18.
In this way information from the CMS base computer can be relayed directly to the field radios 22 or by way of the FILL devices.
A random number generator 30 is shown in block representation coupled to computer 12.
It will be understood that the present invention random number generator 30 can be implemented as part of the computer 12 or can also function as a separate piece of hardware coupled to the computer and tied into the relevant communications channels.
In this way COMSEC keys and key tags can be generated from the computer 12 to the field (SINCGARS) radios 22 to establish secure communications between the radios 22 and the FILL devices 18
