Data sharing platform and security mechanism based on cloud computing under the Internet of Things

Abstract Under the background of the rapid development of information technology, people’s data and information security problems are becoming increasingly serious. Data and information can be leaked in daily Internet access or communications. When doing data sharing, the security mechanism of the data sharing platform should be analyzed. This article aims to study how to analyze the security mechanism of cloud computing-based data sharing platforms in the Internet of Things era. This article presented an attribute-based encryption (ABE) algorithm, a detailed interpretation of the attribute-based encryption algorithm, and analyzed security problems in data sharing in cloud computing. The experimental results showed that the ABE algorithm takes an average of 11 s with five trials, while the other two methods take 51.8 and 31.6 s. ABEs take less time for different encryption numbers under the same data than the other two methods and are more efficient than the other two methods. Thus, attribute-based encryption algorithms should have more advantages.
