- Random seed
A random seed (or seed state, or just seed) is a
number(or vector) used to initialize a pseudorandom number generator.
If the same "random" seed is deliberately shared, it becomes a
secret key, so two or more systems using matching pseudorandom number algorithms and matching seeds can generate matching sequences of non-repeating numbers which can be used to synchronize remote systems, such as GPSsatellites and receivers.
Random seeds are often generated from the state of the computer system (such as the
time), or from a hardware random number generator.
