The need for
random number generator becomes increasingly important for information security applications such as online transactions, online banking, ATM access, and securing of private data and information. In cryptography applications a
true random number generator is necessary required to build ultimate security. To design ultimate
secured encryption system as example, it demands a true random signal
generator to produce key, which increases complexity to the attacker
to crack it. Therefore it is important to have a random signal
generator that can produce true random in information security.
In this section we will discuss on implementation of Random Number Generator in hardware designs. In a hardware design, Random Number Generator (RNG) capabilities are required for generating a
random set of test vectors. Random testing is important since if often
catches hidden bugs in the digital circuit design.
