Diffie-Hellman protocol can be used as a building block for efficient group key establishment.

In hash functions, collision resistant means that we cannot find any two different bitstrings so that they are mapped to the same hash value by using a hash function.

Kerckhoffs’ principle, named after Ron Rivest, Adi Shamir and Auguste Kerckhoffs, is widely accepted in the cryptographic research community.

When passing from the theoretical description of a cryptographic algorithm to its implementation, serious security weaknesses can be introduced even if the correct outputs of the algorithm are produced.
