Secure Multi-party Computation Techniques and Private Semi-trusted Cloud

The main purpose in secure data transmission is related to security of cloud data storage. In this paper, we describe several cryptographic techniques which can be used to address the relevant threats and security goals for analyzing cloud computing security. The private semi-trusted cloud allows researchers to design the private cloud using of the required cryptographic techniques to protect it. Finally, we describe semi-trusted cloud which is related to real-world deployments of cloud resources. This particular cloud leads to optimize the cryptographic protocols and practical solutions for cloud data security.
