Many services have moved to the cloud platform as a result of the dependability and efficiency of cloud computing technologies maturing. Three-factor Mutual Authentication and Key Agreement (MAKA) protocols for multi-server architectures are receiving a lot of interest since they provide easy access to the services and safeguard the privacy of communication on the public network. However, many of the three-factor MAKA protocols now in use either lack a formal security proof, which makes them vulnerable to numerous attacks, or they have large computation and transmission costs. Additionally, the majority of three-factor MAKA protocols lack a dynamic revocation mechanism, making it difficult for unscrupulous users to have their access quickly revoked. We provide a provable dynamic revocable three-factor MAKA protocol to overcome these disadvantages. This protocol uses Schnorr signatures to manage users dynamically and offers a formal security proof in the random oracle. Our protocol can accommodate a range of requirements in multi-server situations, according to security study. Performance research shows that the suggested scheme is ideal for smart devices with limited processing resources. The whole simulation implementation demonstrates the protocol's viability.
