Abstract

Graph theory has many applications in computer science. But it can also be used to make the data secure. Sometime it is used in networking for many purposes. Cloud computing provide user many services like SAAS, IAAS and PAAS. But with many benefit still cloud providers are not too much confident about the security aspects. As for the data storage, cloud data center depends upon third party involvement. So there is need of an algorithm that can authenticate sender and receiver before any transaction between user and third party. The Proposed algorithm uses the adjacency matrix to make the data secure. OTP is one of the attractions used before any transaction.
