报告题目:Efficient Non-Interactive Multi-Client Searchable Encryption with Support for Boolean Queries

报告人:Joseph Liu 讲师

主持人:陈洁  研究员

报告时间:10111400—1500

报告地点:中山北路校区理科大楼B224报告厅

报告摘要:

Enabled by unprecedented amounts of data streaming from all aspects of our lives, Artificial Intelligence has evolved from a nice-to-have add-on to now a must-to-have component in many mission-critical systems for a large variety of applications. In this talk, we first present an overview of the latest research focus of the computational intelligence research group at HKBU related to healthcare and social media analytics. Application domains cover epidemic prediction, daily routine analysis in smart homes, information diffusion modeling, social network alignment, recommender systems, and drug review analysis. Then, we will present two specific research projects reported at IJCAI'16 and UMAP'15, and followed by a glance of some interesting research challenges as our future work.

报告摘要:

Based on the learning with errors over rings assumption (RLWE), a somewhat homomorphic encryption (SWHE) by the approximate eigenvector method is proposed, which security can be reduced to the shortest vector problem on ideal lattices in the worst case. And the leveled fully homomorphic encryption (FHE) is realized by the secret key switching. Combining the public key of leveled FHE with the identity, we bring forward an efficient identity-based leveled FHE scheme from the RLWE assumption. The security analysis shows that our identity-based leveled FHE scheme is selective-ID secure against chosen-plaintext attacks (IND-sID-CPA) in the random oracle model. And the efficiency analysis and simulation results show that the proposed identity-based leveled FHE scheme is much more efficient than Gentry's and Wang's identity-based cryptosystems based on the learning with errors (LWE) assumption.
