Research on Data Sharing Internet plus+Cloud Security Technology Based on Improved Hash Algorithm
The explosive growth of information data has led to a significant trend in data sharing,and cloud storage services have greatly facilitated the acquisition and utilization of data.However,they have also invisibly increased the risk of data leakage and changes,which can easily lead to data security issues and panic among people.Therefore,based on the advantages of traditional hash algorithms in the field of encryption,this study starts with the addition of scalable precision chaos theory and cloud storage of data,in-cluding the introduction of dual chaos parameters,consideration of time and cost models,and the design of security architecture for re encrypted cloud platforms.The application effectiveness was verified through experimental testing,and the results showed that the im-proved hash algorithm passed security and randomness tests.Its uniformity in ciphertext space was good,and there was a significant difference of at least 600ms in maximum runtime compared to other algorithms.The search quality was good,and its security rate in information leakage,identity forgery,and security vulnerability attacks exceeded 85％.The algorithm proposed in the study can effec-tively provide reference value for internet data sharing and cloud security guarantee technology.
