报告简介：

In this speech, the research activities of cyber security in the School of Electrical and Electronic Engineering at Nanyang Technological University in Singapore will be first introduced. As an example, one aspect of the security of cloud computing, key management for authentication, will be presented. Cloud computing technology is an emerging technology for various types of vast information to be processed in the data centres to overcome the serious shortage of resource such as space, power and cost, etc. Along with the development of cloud computing, security of cloud computing is becoming more and more critical. In this work, we aim to builda set of secure and efficient authenticated multi-party key agreement protocols based on the hierarchical identity-based cryptography (HIBC) for private cloud. For different scenarios, we design loop-level and cascade-level authentication protocols among users in a private cloud of hierarchical structure, respectively. The new multi-party protocols are supposed to be more efficient and secure than the other existing solutions.
