Abstract:

This paper takes information security architecture of smart city as a core subject research in top planning and designs phase during smart city construction, and harmonious and difference design disciplines are proposed. A hierarchical architecture of information security framework for smart city based on PKI/CA infrastructure is designed separately which supports a smart security engine and plug in smart application adapters via a security information bus. Proper information security strategy, security risk assessment, security audit mechanism and security monitoring system are further described. Key implementation techniques related to the four platform architecture are discussed respectively including security technique, information fusion technique, big data mining technique, and security evaluation technique. Smart city construction is a high investment with long term and far reaching significance. It is meaningful for current smart city construction and new urbanization construction.

Key words: smart city, information security, top design, smart information security engine, smart application
