A random seed (or seed state, or just seed) is a number (or vector) used to initialize a pseudorandom number generator. A number is an Abstract object, tokens of which are Symbols used in Counting and measuring. In Computer science an array is a Data structure consisting of a group of elements that are accessed by indexing. A pseudorandom number generator ( PRNG) is an Algorithm for generating a sequence of numbers that approximates the properties of random numbers

The choice of a good random seed is crucial in the field of computer security when a secret encryption key is pseudorandomly generated, a way to find it is to look for the seed used. This article describes how security can be achieved through design and engineering In Cryptography, a key is a piece of information (a Parameter) that determines the functional output of a cryptographic algorithm Key generation is the process of generating keys for Cryptography.

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 GPS satellites and receivers. In Cryptography, a key is a piece of information (a Parameter) that determines the functional output of a cryptographic algorithm Basic concept of GPS operation A GPS receiver calculates its position by carefully timing the signals sent by the constellation of GPS Satellites high above the Earth

Random seeds are often generated from the state of the computer system (such as the time), or from a hardware random number generator. For other uses see Time (disambiguation Time is a component of a measuring system used to sequence events to compare the durations of In Computing, a hardware random number generator is an apparatus that generates Random numbers from a physical process
