(John Preuss Mattsson)
John is an expert in cryptographic algorithms and security protocols at Ericsson Research in Stockholm, Sweden. His work focuses on applied cryptography, security protocols, privacy, IoT security, post-quantum cryptography, and trade compliance. During his almmost 20 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 cryptography, Internet, and cellular security standards. In addition to designing new protocols, John has also found significant attacks on many algorithms and protocols. John holds an MSc in engineering physics from KTH Royal Institute of Technology, Sweden, and an MSc in business administration and economics from Stockholm University.
