One is to use an external noise source, which may be compromised, or may not be always available (for example in secure locations with controlled environment). To obtain randomness, you have two solutions. TRNGs rely on classical physics, which is intrinsically deterministic. TRNGs require a physical source of randomness, which outputs digitized results of a measured physical event. In order to adapt this processing to the source, the imperfections have to be well understood and monitored. In both cases, since physical systems are not perfect, both TRNGs and QRNGs depend on some mathematical processing to reach perfect randomness. QRNGs are indeed True RNGs, but they are considered as separate. In contrast, for Quantum RNGs or QRNGs the source of randomness is a quantum process. The so-called True RNGs or TRNGs, are RNGs where the source of randomness relies on classical physics. Unfortunately, the terminology is slightly confusing. Hardware devices allow us to get closer to true secure randomness. To get good cryptographic randomness, the seed of a PRNG has to be both random and private, which brings us back to the original problem of how to generate this random seed. The output of a PRNG depends deterministically on an input, known as the seed. Although they offer a low-cost introduction to randomness, the problem with PRNGs is that they are deterministic. Software RNGs are also known as Pseudo RNGs or PRNGs, which gives you a clue to exactly how truly random the output is. RNGs can basically be divided into two fundamental types: software and hardware. The degree of security is subject to several internal and external factors.
