Abstract
The new developments in smart cyber-physical systems can be shown to include smart cities, Internet of things (IoT), and for the most part smart anything. To improve the security of sensitive personal information (SPI) in cyber-physical systems, we present some novel ideas related to the encryption of SPI. Currently, there are issues in traditional encryption methods, such as low speed of information acquisition, low recognition rate, low utilization rate of effective information resources, and high delay of information query. To address these issues, we propose a novel efficient encryption algorithm for the security of incremental SPI. First, our proposed method analyzes user information resources and determines valid data to be encrypted. Next, it uses adaptive acquisition methods to collect information, and uses our encryption method to complete secure encryption of SPI according to the acquisition results. Our experimental analysis clearly shows that the algorithm effectively improves the speed of information acquisition as well as effective information recognition rate, thus enhancing the security of SPI. The encryption model in turn can provide a strong guarantee for user information security.

Summary
As users of smart devices, we have witnessed advancements in systems that are Internet based, which have created many different new avenues and challenges. CPS can integrates the dynamics of physical processes with those of both networking and software, providing the necessary abstractions, design, and analysis techniques needed to further their very nature. As indicated earlier, with SPI potentially flowing freely in CPS based networks, the need for the security of such information to be preserved is mandatory and can be provided through our work presented here. Our algorithm analyzes user data resources and encrypts the data according to the analysis results gauging the type of data involved This effectively solves the problem of data query delays caused by traditional methods in encrypting large amounts of data by only encrypting data that needs enhanced security and privacy. The experimental results show that the proposed algorithm effectively solves the shortcomings of traditional methods, and can protect a users’ privacy and information security.
