A New and Advanced Method for Cloud Data Security

We are introducing and implementing a novel method for cloud data security in this paper. In this novel method, five arithmetic operations which are basic (i.e. Addition, Subtraction, Multiplication, Division and Modulo) are performed on ASCII digits of every cover text character and these values which are newly generated are used for encryption of plain text parallelly. These each new generated values and two plain text characters in ASCII code will be encrypted in parallel way from beginning and from end of plain text. One cover text character hides at most ten plain text characters in our proposed approach. Since only one cover text character is used therefore less memory is required for storing cover text on cloud storage. Since we are using basic arithmetic operations therefore execution time is reduced and due to our parallelism approach, performance of overall system is enhanced.
