  • Apparatus and method for a pseudo-random number generator for high precision numbers
    Patent number: 5541996
    Abstract: The present invention pseudo-random number generator produces a high precision number suitable for use as a data encryption communications security (COMSEC) key from a highly mobile computer platform. The random number generator is especially suitable for use with military radios and other like applications requiring a random number bit string of high precision. The present invention random number generator produces four pseudo-random numbers of 32-bits and uses only the last 28 bits of each number. A multiplicative linear congruential generator with multiplier 16807 and prime modulus 2.sup.31 -1 is used to produce the 32-bit pseudo-random numbers. This generator produces a sequence of remainders of large modulus. The last 28 bits of the 32-bit numbers are combined to produce one high precision number of 112 bits.
