Secrecy, Authentication, and Public Key Systems

Title: Secrecy, Authentication, and Public Key Systems

Summary: Merkle's PhD Thesis

Field: Cryptography

Author: Ralph Charles Merkle

Published: June 1979

Abstract:

This thesis describes Ralph Merkle's work between 1974 and 1979 on a variety of cryptography-related topics. The presentation will include a subset of the thesis's findings, due to the thesis's large size and the presentation's limited time. This thesis introduce Merkle's Puzzles, a public-key cryptosystem allowing two users to establish an encrypted channel without any secrets shared beforehand. It also covers the trapdoor knapsack and signature schemes.
