Essentially, the algorithm exercises LSB replacement using the definition for steganographic values from F5. After the nonzero quantized DCT coefficients of a cover image undergo a pseudorandom walk, the coefficients and the payload are split into an equal number of partitions and paired. Each ...
no, pseudorandom numbers are not truly random. while they may exhibit random-like properties, they are entirely determined by the seed value and the algorithm used to generate them. given the same seed, a pseudorandom number generator will always produce the same sequence of numbers. however, ...
Computers normally cannot generate really random numbers, but frequently are used to generate sequences of pseudo-random numbers. These are generated by some algorithm, but appear for all practical purposes to be really random. Random numbers are used in many applications, including simulation. A co...

An alternative to producing the same sequence of RNs each time a program is run is to use apseudorandomnumber generator (PRNG). Such a generator uses a deterministic algorithm that, given the previously generated numbers (often just the last few), the next number can be efficiently calculated...

First number: 41 Random number: 13 Again the first number: 4 rand function int rand ( void ); Generate random number Returns a pseudo-random integral number in the range 0 to RAND_MAX. This number is generated by an algorithm that returns a sequence of apparently non-related numbers each...
The DSS signature algorithm requires the signer to generate a new random number with every signature. We show that if random numbers for DSS are generated using a linear congruential pseudorandom number generator (LCG) then the secret key can be quickly recovered after seeing a few signatures. ...
void srand48(long intseedval); General description The drand48(), erand48(), jrand48(), lrand48(), mrand48() and nrand48() functions generate uniformly distributed pseudo-random numbers using a linear congruential algorithm and 48-bit integer arithmetic. ...
