The PRNG variable is defined in NIST SP 800-90 as a number associated with the amount of work required to break a cryptographic algorithm or system.

Strength

Explanation:

A huge number of systems use a process called Pseudo Random Number Generation (PRNG). In NIST SP 800-90, The PRNG has a set of parameters that define various variables within the algorithm. The PRNG variable strength is defined in NIST SP 800-90 as a number associated with the amount of work required to break a cryptographic algorithm or system.

i want to say d but i could be wrong however it is organized if that could happen..

hope it could
