Abstract This chapter discusses cryptographic mechanisms supporting different strengths of data integrity. It first covers hash functions, whose three core security properties are motivated by means of different use cases. It shows how the implications of birthday attacks dictate the output length of a hash function.

Processes on the planet Earth are complex phenomena that are taking place in space and in time, i.e. in four dimensions. In many of these processes, differences in one dimension (e.g. height above the geoid) can be disregarded, so that two spatial dimensions and the dimension time remain.
