SECURE AND RESILIENT VIDEO BLOCK MANAGEMENT AND PRINCIPLES FOR ZERO TRUST CLOUD NETWORK

Cloud computing principles are widely applied to provide reasonable network services to a range of users. In addition to the basic services of cloud networks, security features are highly expected at the user end. Considering these issues as a scope of this article, various existing techniques are identified. The existing solutions on zero trust cloud network target single mode encryption model irrespective of data models. However, the video content delivery systems in cloud platforms need multiple modes of secure data transmissions. According to that, the proposed Secure and Resilient Video Block Management (SRVM) model has been developed to attain both real-time and non-real-time security constraints. On the basis, this proposed model uses switchable block cipher and stream cipher model with respect to video data transmission modes. Similarly, the data blocks collected in the cloud environment are effectively distributed among cloud virtual machines and data is encrypted in a complex manner. This kind of novel idea reduces the chances of data confidentiality breaches and data losses due to attackers. The experiments have been conducted between SRVM, Blockchain based Multimedia Data Security (BMDS), Firefly Optimization and Encryption (FFOE), and Quality of Everything in Edge based Encryption (QMEE) to ensure the testbed performances. In this experiment, the proposed model works 10% to 15% optimally than existing techniques and the details are observed through multiple test cases.
