Title: Public Key Encryption for the Forgetful

Speaker: Prof. Yuliang Zheng (University of North Carolina at Charlotte)

Abstract:We investigate public key encryption that allows the originator of a ciphertext to retrieve a ``forgotten'' plaintext from the ciphertext. This type of public key encryption with ``backward recovery'' contrasts more widely analyzed public key encryption with ``forward secrecy''. We advocate that together they form the two sides of a whole coin, whereby offering complementary roles in data security, especially in cloud computing, 3G/4G communications and other emerging computing and communication platforms.

Biography:Professor Yuliang Zheng is known as the father of signcryption and is internationally recognized as an authority in cryptography and network security. He has published over 200 scholarly articles and books on security and holds a multiple number of patents in cyber security. He plays an active, leadership role in international research communities. He co-founded the annual Public Key Cryptography (PKC) conferences sponsored by the International Association for Cryptologic Research (IACR), and serves as the chair of the steering committee of PKC.

He serves also on the steering committees for a number of other research and industrial forums including Information Security Conference (ISC), IEEE Information Assurance Standards Committee, and Workshop on Long-Term/Information-Theoretic Security. Professor Zheng was invited to serve as an associate editor of The Computer Journal published by the Oxford University Press and as a guest editor for the IEEE Transactions on Information Theory.

His pioneering work on immunizing public key encryption against adaptive attacks has been embodied in a number of international standards. Currently, ISO (International Standards Organization) is in the process of establishing a set of new standards on signcryption techniques invented by Professor Zheng.

Professor Yuliang Zheng earned his Bachelor of Science degree with Highest Distinction in computer science from the Nanjing Institute of Technology in 1982. He then won a prestigious young researcher's award from the Ministry of Education for studies at Yokohama National University in Japan, where he earned his master's and PhD degrees in electrical and computer engineering. After completing his PhD, Professor Zheng moved to Australia, working at first as a cyber security research scientist at the Australian Defense Force Academy, and then as a professor at the University of Wollongong and Monash University. In 2001, Professor Zheng was recruited as one of the top 10 international experts in cyber security to join the faculty of University of North Carolina at Charlotte in USA.
