CERTIFICATE AUTHORITY ENHANCED CLOUD SECURITY

Abstract

In this era of information sharing “cloud computing” plays a vital role for storing and accessing data over internet via secured as well as unsecured computer network. Due to ease of access of clouds, information security is becoming an issue for those who are transmitting and receiving sensitive information through cloud. Here we are trying to solve this problem using some cryptographic mechanism. In this paper we will use the concept of registration authority and certificate authority to identify that the communicating entity is supposed to do so or not. Certificate authority is a trusted third party who is responsible to provide certificate and access level for nodes which are trying to communicate with cloud. First of all, an incoming node must have to communicate with certificate authority with their credentials for acquiring certificate for communicating with cloud. Those credentials are checked and verified by certificate authority and then a certificate is granted to that node. Once certificate is granted, that certificate is shared to cloud server also for matching purpose, when the corresponding will communicate with cloud server. If everything will happen in right manner then that node can access cloud data according to their access level.
