Abstract

With the rapid development of information technology, privacy protection has become an urgent and important topic in the field of computer science. This study focuses on the application of computer security protocols in privacy protection, aiming to provide users with more reliable and efficient privacy protection mechanisms through the construction and optimization of a security protocol system. Based on an in-depth analysis of existing privacy threat models, this research proposes a security protocol fr amework that integrates identity authentication and data encryption. This fr amework not only effectively resists common network attacks but also ensures the integrity and confidentiality of user information during transmission. Empirical studies conducted across various typical application scenarios, such as e-commerce and social networks, demonstrate that the proposed protocol fr amework significantly reduces the risk of privacy leakage, particularly excelling in handling large-scale concurrent access. Additionally, this study innovatively incorporates zero-knowledge proof technology, minimizing the exposure of sensitive information during user identity verification, thereby further enhancing system security. Experimental data show that, without compromising user experience, the new protocol reduces the probability of privacy leakage by approximately 30% and improves system response speed by over 25%. In conclusion, this study provides new ideas and technical means for privacy protection, playing a significant role in advancing the development of information security.
