The proposed TRNG was tested according to FIPS 140-1/2 and AIS test suits.
The TRNG which is developed to be GARO-based has D-type and toggle flip-flops.
In another study, TRNG in Open Loop Structure is proposed in order to use generated numbers in cryptography applications .
Apart from mentioned studies, an ASIC application of TRNG is developed .
PRNG and chaos-based random number generators are used with TRNG in duplicate structures , .
A typical TRNG consists of three components as shown in Fig.
Randomness of numbers generated by RO-based TRNG depends on randomness of jitter signal obtained by each RO.
The TRNG in the proposed system is composed of only RO and binary XOR tree logic gates.
The usage of TRNG structure implemented on two different FPGA boards is not suitable for cryptographic applications due to security reasons.
The TRNG structure implemented on two different FPGA boards is not convenient for cryptographic application due to security reasons.

While TRNGs are expensive and slow for many applications, PRNGs are effective and more appropriate for many applications because they have more simple structure.
