HAIC talk: Current State of Applied Cryptography – Attacks, Standardization, Government Requirements, and Best Practices – with John Mattsson

31/10/2022 @ 16:00 - 17:30


Speaker: John Mattsson, Ericsson Research, Sweden

Lecture description: Applied cryptography has been a very active area in the last 10 years since the Snowden revelations. From being used selectively, cryptography is now used everywhere for both security and privacy. To prevent pervasive monitoring, mandatory to use encryption, identity protection, and perfect forward secrecy are now seen as requirements. The increased use of crypto has put new requirements on performance, and old standards with questionable security have been replaced with new high-performance algorithms with improved side-channel protection. Current activities include aligning with zero trust principles and making systems resistant to attacks from quantum computers. This talk will explain how and why applied cryptography has evolved in recent years and how it will change with the introduction of post-quantum algorithms and key encapsulation mechanisms.

About the speaker:  John is an expert in cryptographic algorithms and security protocols at Ericsson Research. His work focuses on applied cryptography, security protocols, privacy, IoT security, post-quantum cryptography, and trade compliance. During his 15 years at Ericsson, he has worked with a lot of different technology areas and been active in many security standardization organizations including IETF, IRTF, 3GPP, GSMA, and NIST where he has significantly influenced Internet and cellular security standards. In addition to designing new protocols, John has also found significant attacks on many algorithms and protocols including Polar Bear, GCM, SRTP, CoAP, and SCTP. John holds an M.Sc. in engineering physics from KTH Royal Institute of Technology, Sweden, and an M.Sc. in business administration and economics from Stockholm University.
