Abstract:

Human society has completely entered the information age, the amount and complexity of information in modern society has exceeded peoples' vision in ten or twenty years ago. How to make use of big data within the national legal framework is important, it is a great challenge for the researchers of information security to coordinate and process the contradiction between the openness of big data and the protection of information. ICT (information and communication technology) is used to realize sustainable development of smart city. With the rapid increasing of big data in the construction and implementation of smart city, there are great challenges in data collection transmission storage and audit. The security of big data is the foundation and assurance of smart city. This paper analyzes the security policies during data storage data application and data management, introduces a multi-label based access control model for big data, which the owners of the data can add security labels to implement security access control according to the real security requirements. Taking the construction of London smart city as example, this paper analyzes the key function of big data in smart city.

Key words: smart city, big data, security challenge, security policy, access control
