The Main Event
David Murray presents New Directions in Cryptography ( and A Method for Obtaining Digital Signatures and Public-Key Cryptosystems (

These two classic papers are big favorites of mine. New Directions in Cryptography introduced the idea of digital signatures and public key cryptosystems, and reduced both problems to the search for a trap-door one-way permutation. Although Diffie and Hellman were unable to come up with such a permutation (settling for "just" Diffie-Hellman-Merkle key exchange), they laid the theoretical framework and invited others to join the search. Rivest, Shamir, and Adleman read the paper, did a lot of hard thinking, and a year later published A Method for Obtaining Digital Signatures and Public-Key Cryptosystems - now known as the RSA algorithm.
