报告题目：Trusted Computing and the “Cyber Security Ecosystem”
报告内容：The cyber security ecosystem includes a wide range of interactions and an arms race between cyber attackers and defenders. Modern cryptographic research is part of this ecosystem and contributes to both sides; identifying weaknesses in current algorithms and developing new ones. As a cryptographic engine, the trusted platform module (TPM) has been developed in this ecosystem. A TPM is a small chip that is embedded in a host platform. It serves as a root of trust and provides an attestation service on the behalf of its host. If, as predicted, a large-scale quantum computer becomes a reality in the near future, existing public-key algorithms, supported by the TPM, will be open to attack. A smooth transition from today’s TPM to a future quantum-resistant TPM is required. In this talk, we will use TPM development as an example to discuss the cyber security ecosystem.
报告人简介：Liqun Chen is a Professor in Secure Systems at the University of Surrey, UK. Prior to joining Surrey in 2016, she was a principal research scientist at Hewlett Packard Laboratories in Bristol. During her 19 years working for the company, she obtained 64 granted US patents with 35 further applications pending, many of which are about the Trusted Platform Module (TPM). She designed a number of the cryptographic algorithms used in the Trusted Platform Mod­ule and also developed several cryptographic schemes adopted by ISO/IEC and IEEE. She has an extensive publication record; her co-authored paper, describing direct anonymous attestation, was given a test of time award at ACMCCS 2014. She is the technical leader in the EU H2020 project FutureTPM, which aims to develop a post-quantum TPM.
