Education and early life[edit]
Kocher grew up in Oregon. He received a bachelor's degree in biology from Stanford University in 1991, where he worked part-time with Martin Hellman.
Career and research[edit]
Kocher was awarded the 2019 Marconi Prize with Taher Elgamal for architecting the Secure Sockets Layer (SSL) 3.0/Transport Layer Security (TLS) 1.0 protocol, a cryptographic protocol for secure communications on the Internet.
He pioneered the field of side-channel attacks, including the development of timing attacks that can break implementations of RSA, DSA and fixed-exponent Diffie–Hellman that operate in non-constant time[1], as well as the co-development of power analysis and differential power analysis[2]. His side-channel attack countermeasure designs are widely deployed in secure integrated circuits and other cryptographic devices.[3] He has also worked on microprocessor security, and co-discovered and named the Spectre vulnerability, which leverages speculative execution and other microprocessor performance optimizations to extract confidential information.
He also helped architect security-related integrated circuits, including Deep Crack, a DES brute-force key search machine.
Honors and awards[edit]
Kocher was elected to the U.S. National Academy of Engineering in 2009 for his contributions to cryptography and Internet security. He serves on the National Academies' Forum on Cyber Resilience. [4]
In 2018, Kocher was named a Fellow of the International Association for Cryptologic Research for "fundamental contributions to the study of side-channel attacks and countermeasures, cryptography in practice, and for service to the IACR."[5]
Kocher and Taher Elgamal were jointly awarded the 2019 Marconi Prize for "their development of SSL/TLS and other contributions to the security of communications".[6]
