In the Hybrid cloud deployment model, security is essential to restrict access while using resources such as virtual machine, platform, and application. Many protocols were developed to provide security via the cryptography technique, but these protocols rarely considered the trust factor which is an essential factor for cloud security. The existing Elliptic Curve Cryptography and Diffie Hellman key distribution mechanism failed to stress the trust factor, and further, they have provided not only higher complexity but also lower security and reliability. The proposed method comprised two stages: first stage, Group Creation using the trust factor and develop key distribution security protocol. It performs the communication process among the virtual machine communication nodes. Creating several groups based on the cluster and trust factors methods. The second stage, the ECC (Elliptic Curve Cryptography) based distribution security protocol is developed. The proposed Trust Factor Based Key Distribution Protocol reduced error rate, improve the key computation time and maximize resource utilization.
