As demand for Kocher's knowledge in cryptography escalated, he gave up on his original plan to become a veterinarian and founded CRI instead.
[2] His side-channel attack countermeasure designs are widely deployed in secure integrated circuits and other cryptographic devices.
He also helped architect security-related integrated circuits, including Deep Crack, a DES brute-force key search machine.
[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".
