Early life and education

Merkle graduated from Livermore High School in 1970 and proceeded to study computer science at the University of California, Berkeley, obtaining his B.A. in 1974, and his M.S. in 1977. In 1979 he received his Ph.D. in electrical engineering at Stanford University, with a thesis entitled Secrecy, authentication and public key systems; his advisor was Martin Hellman.

Contributions

Merkle devised a scheme for communication over an insecure channel: Merkle's puzzles as part of a class project while an undergraduate.[2] The scheme is now recognized to be an early example of public key cryptography. He co-invented the Merkle–Hellman knapsack cryptosystem, invented cryptographic hashing (now called the Merkle–Damgård construction based on a pair of articles published 10 years later that established the security of the scheme), and invented Merkle trees. While at Xerox PARC, Merkle designed the Khufu and Khafre block ciphers, and the Snefru hash function.

Career

Merkle was the manager of

  • Oral history interview with Martin Hellman Oral history interview 2004, Palo Alto, California. Charles Babbage Institute, University of Minnesota, Minneapolis. Hellman describes his invention of public key cryptography with collaborators Whitfield Diffie and Ralph Merkle at Stanford University in the mid-1970s. He also relates his subsequent work in cryptography with Steve Pohlig (the Pohlig–Hellman system) and others.
