Cloud computing has come to be on the top of any list of topics in the fields of computer because of its cost effectiveness. Storage and maintenance of large amount of data used to be a nightmare of the end users, but the advent of cloud computing gave them breathers because of its third party computing capabilities, thereby cutting the cost of infrastructure and man power. Moreover cloud computing has greater flexibility and reliability. Since it has effected a paradigm shift in the whole field of computing, it has become an unavoidable concept with any government in the field of e-governance and rural development in the developing world, shifting the entire concept of computing from the user-owned network infrastructure to the third party computing capability, sourcing data from a server situated not in the user’s location but somewhere else. At the same time a word of caution becomes inevitable on the security aspect of the stored data which is kept in the open environment. This paper explores the possibility of securing the users’ data more effectively using MRSA algorithm.
