报告摘要:
         Recent years have witnessed massive and wide deployment of IoT devices, ranging from smart cards to implanted medical devices. It is estimated that 50 billion IoT devices will be connected by year 2020. The diverse feature of IoT devices results in many special requirements to cryptographic mechanisms over traditional ones, such as low hardware area when implemented on small devices or low energy consumption when running on devices powered by limited battery. We show, by examples of concrete designs, how effective cryptographic mechanisms are still possible under these constraints without affecting the security strengths. It is also interesting to note that a single algorithm could be implemented in several ways to fit very different IoT usecase scenarios while keeping the functionality and security strength unaffected.

报告人简介:
         GUO Jian received his B. Eng with First class honors from School of Computer Engineering, and PhD from School of Physical and Mathematical Sciences of Nanyang Technological University in Singapore in 2007 and 2011, respectively. He then worked with Institute for Infocomm Research in Singapore for 2.5 years, and returned to NTU as a researcher in 2013. He subsequently joined Temasek Labs as a Principal Investigator and SPMS as an Assistant Professor. His major research interest is symmetric-key cryptography, including cryptanalysis, design and implementation of (lightweight) hash functions, block ciphers, authenticated encryption schemes, and their applications such as message authentication codes. He co-designed PHOTON --- one of the ISO standards of lightweight hash functions, CLOC and SILC authenticated ciphers --- one of the third round candidates of the on-going CAESAR competition, as well as LED --- one of the lightest block ciphers suitable for constrained hardware. He has done some intensive cryptanalysis against various cryptographic primitives including the latest NIST hash function standard SHA-3, on which he and his team won several awards. Among others, he published 20+ papers in top conferences under the International Association for Cryptologic Research (IACR). He is founding co-chair of ASK — the Asian workshop on Symmetric-Key cryptography. He served as general co-chair of FSE 2013, program committee members of FSE 2017, ASIACRYPT 2017, FSE 2018, EUROCRYPT 2018 etc, and reviewer for all major cryptography conferences and journals. He is a member of ASIACRYPT steering committee representing for Singapore, and also a member of the Security and Privacy Standards Technical Committee acting as Singapore delegate of the International Standardization ISO/IEC JTC 1/SC 27. His research attracted government research grants worthing a total of more than one million Singapore dollars, with which he recruited and manages the Cryptanalysis Taskforce research group at NTU.
