How to test hardware of random number generators?
A hardware random number generator is an electronic device that plugs into a computer and produces genuine random numbers.
I would like to know:
How to test hardware random number generators?
What techniques, tools or tricks to solve the problem?
Any practical difficulties, implementation complexities etc.?
Are there any bounds on this problem?
For actually testing an RNG look up the Diehard and Dieharder test libraries, the latter being more recent.
