hash function

The basic idea is to use two hash functions instead of only one.

However, using a larger table and/or a better hash function may be even more effective in those cases.

It is also why hash functions have large data blocks.

Contrary to its name, it does not use hash functions.

And the idea is that you want to incorporate a key into the hash function.

The hash function reads a name and gives back a number.

So it's a way of taking a standard hashing function, but for your particular purpose.

The two hash functions should be independent and have no correlation to each other.

An attack on the hash function thus should not be able to find a collision with less than about 2 work.

For additional hash functions see the box at the bottom of the page.

The random state is the 160-bit output of the hash function.

At the beginning of the call, both users get the same session key by using the hash function.

Generally, and are selected from a set of universal hash functions.

The search for a "good" hash function has thus become a hot topic.

It's sort of the way we found some collisions with the smaller hash functions.

So a 128-bit block cipher can be turned into a 256-bit hash function.

In general, a hashing function may map several different keys to the same index.

A hash function will always generate the same output for a given input.

Some popular hash functions do not have this property.

Both hash functions are used to compute two table locations.

Then, for a good hash function, is approximately the probability of a hard collision.

The technique is based on digital signatures and hash functions.

Other construction methods for hash functions have been proposed to better fit the data.

The solution to these problems is to pick a function randomly from a family of hash functions.

This approach generally depends on assumed properties of the hash function.
