Research on data security and privacy protection of blockchain cloud computing based on chaotic cryptography and RSA algorithm
The rapid development of blockchain technology provides new solutions for cloud computing,however,data security and privacy protection remain a key challenge.To address these issues,the study proposes a method based on the combination of cha-otic cipher and RSA algorithm for enhancing the security and privacy protection of blockchain cloud computing data.The results of the study show that the chi-square value of Lena image at a significance level of 0.05 is 255.2,which is less than the expected value.This indicates that chaotic cipher combined with RSA algorithm has high resistance to attacks.The pseudo-randomness and highly complex computational process of chaotic cipher makes it difficult for attackers to crack the encrypted data,thus effectively protecting the user data from being stolen or tampered with,and the combination of the RSA algorithm can improve the efficiency of encryption and decryption and reduce the computational complexity while guaranteeing the security of the data.The research improves the securi-ty and privacy protection level of data on the blockchain cloud computing platform,providing users with more secure and reliable cloud computing services.
