Abstract:
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.
Biography:
GUO Jian is currently an Assistant Professor with Nanyang Technological University in Singapore. His major research interest is symmetric-key cryptography. 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 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 more than 30 papers in top conferences under the International Association for Cryptologic Research. 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, Asiacrypt, and Eurocrypt constantly. He is a member of ASIACRYPT steering committee representing for Singapore, and also a member of the Security and Privacy Standards Technical Committee in Singapore acting as delegate of the International Standardization ISO/IEC JTC 1/SC 27. He has been leading the Cryptanalysis Taskforce research team in NTU since 2014.
