In 2002, Hellman suggested the algorithm be called Diffie – Hellman – Merkle key exchange in recognition of Ralph Merkle's contribution to the invention of public-key cryptography ( Hellman, 2002 ).
While that system was first described in a paper by Diffie and me, it is a public key distribution system, a concept developed by Merkle, and hence should be called ' Diffie – Hellman – Merkle key exchange ' if names are to be associated with it.
Knapsack problems appear in real-world decision-making processes in a wide variety of fields, such as finding the least wasteful way to cut raw materials, selection of capital investments and financial portfolios, selection of assets for asset-backed securitization, and generating keys for the Merkle – Hellman knapsack cryptosystem.
He co-invented the Merkle – Hellman knapsack cryptosystem, Merkle – Damgård construction, and invented Merkle trees.

A hash function built with the Merkle – Damgård construction is as resistant to collisions as is its compression function ; any collision for the full hash function can be traced back to a collision in the compression function.
An extension of the collision attack is the chosen-prefix collision attack, which is specific to Merkle – Damgård hash functions.

Merkle and was
Nineteen-year-old rookie first baseman Fred Merkle, later to become one of the best players at his position in the league, was on first base, with teammate Moose McCormick on third with two out and the game tied.
However, Merkle, instead of advancing to second base, ran toward the clubhouse to avoid the spectators mobbing the field, which at that time was a common, acceptable practice.
For his part, Merkle was doomed to endless criticism and vilification throughout his career for this lapse, which went down in history as " Merkle's Boner ".
