hash-function
a function which maps strings of bits to fixed-length strings of bits, satisfying the following two properties: - it is computationally infeasible to find for a given output, an input which maps to this output; - it is computationally infeasible to find for a given input, a second input which maps to the same output NOTE Computational feasibility depends on the specific security requirements and environment.

A function which maps strings of bits to fixed-length strings of bits, satisfying the following two properties: It is computationally infeasible to find for a given output an input which maps to this output, It is computationally infeasible to find for a given input a second input which maps to the same output.
source: ISO13888-1, 2004
[ISO/IEC 10118-1] A function which maps strings of bits to fixed-length strings of bits, satisfying the following two properties: - for a given output, it is computationally infeasible to find an input which maps to this output; and - for a given input, it is computationally infeasible to find a second input which maps to the same output. NOTE Computational feasibility depends on the specific security requirements and environment.
source: ISO15946-2, 2002
a function which maps strings of bits to fixed-length strings of bits, satisfying two properties. - it is computationally infeasible to find for a given output, an input which maps to this output; - it is computationally infeasible to find for a given input, a second input which maps to the same output. NOTES 1 The literature on this subject contains a variety of terms which have the same or similar meaning as hash-function. Compressed encoding and condensing function are some examples. 2 Computational feasibility depends on the users specific security requirements and environment.
