摘　　要：区块链技术的快速发展为云计算提供了新的解决方案,然而,数据的安全性和隐私保护仍然是关键挑战。为了解决这些问题,研究提出了一种将混沌密码与非对称加密算法相结合的方法,用于增强区块链云计算数据的安全性和隐私保护。研究结果表明,Lena图像在显著性水平为0.05时的卡方值为255.2,小于期望值,这说明混沌密码结合RSA算法具有较高的抗攻击能力。混沌密码的伪随机性和高度复杂的计算过程使得攻击者难以破解加密数据,从而有效保护用户数据不被窃取或篡改,结合非对称加密算法可以在保证数据安全的同时,提高加密和解密的效率,降低计算复杂度。研究提高了数据在区块链云计算平台上的安全性和隐私保护水平,为用户提供更安全、更可靠的云计算服务。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 chaotic 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 security and privacy protection level of data on the blockchain cloud computing platform,providing users with more secure and reliable cloud computing services.
