报告内容摘要：In this talk, the speaker will present their recent results on efficient key managements in mobile ad hoc networks (MANETs). Their new results on key revocation and key renewal schemes for identity based cryptographic primitives for MANETs will be introduced:   It is a fully self-organized revocation scheme, for which each node monitors nodes in communication range and securely propagates its observations. The public key of a node is revoked if the number of nodes that accused the node reaches a threshold value, which is a security parameter. To enable key renewal, a modified format for ID-based public keys is employed, such that new keys can be issued for the same identity. The introduced revocation scheme is efficient because it uses pre-shared keys from the pairing and messages are sent to an m-hop neighborhood instead to the entire network.

  

报告人简介：Guang Gong received a B.S. degree in mathematics in 1981, a M.S. degree in applied mathematics in 1985,  and a Ph.D. degree in electrical engineering in 1990, from universities in China. She received a Postdoctoral Fellowship from the Fondazione Ugo Bordoni, Rome, Italy, and spent the following year there. After return from Italy, she was promoted to an Associate Professor at the University of Electrical Science and Technology of China. Since 1995, she had worked with several internationally recognized outstanding coding experts and cryptographers including Dr. Solomon W. Golomb at the University of Southern California, Los Angeles. She joined, as an Associate Professor, the Department of Electrical and Computer Engineering, University of Waterloo, Ontario, Canada, in September 2000. She is a Professor since 2004. Her research interests are in the areas of sequence design, cryptography, and network security. She has authored or co-authored more than 130 technical papers and one specialized book, co-authored with Dr. Golomb, entitled as “Signal Design for Good Correlation --  for Wireless Communication, Cryptography and Radar”. She is an Associate Editor of IEEE Transactions on Information Theory for sequences.

 

Dr. Gong has received several awards including the Best Paper Award from the Chinese Institute of Electronics in 1984, Outstanding Doctorate Faculty Award of Sichuan Province, China, in 1991 and the Premier's Research Excellence Award, Ontario, Canada, in 2001.
