PRNG is an algorithm for creating a sequence of numbers whose properties almost equal to the properties of sequences of random numbers.
A PRNG, S, which generates binary libit key streams, is called an ideal PRNG, if S has the following properties:
While TRNGs are expensive and slow for many applications, PRNGs are effective and more appropriate for many applications because they have more simple structure.
This is also a very undesirable situation since it makes the outputs of the PRNG not random at all.
The PRNG algorithm was programmed to provide an integer between 0 and 99 inclusive, and an even value was coded as a 'tail' and an odd value as a 'head'.
Thus, users may add their own PRNG by rewriting two dummy SPRNG functions and recompiling SPRNG.
The elements of PRNGs that are most used in stream ciphers are Linear Feedback Shift Registers (LFSRs), because LFSR of length n can generate a PRS of maximum length T = [2.
The reader generates and saves a pseudo random number r by utilizing PRNG and sends a query request to the tag.
However, nobody knew until the later time of feedback which target the PRNG had selected.
Then, the authentication code C is generated PRNG with the seed K.
RNG and PRNG are having applications in various areas like: stream cipher, block cipher, key generation, initial vectors etc.
