Today various numbers of   diverse applications that include e- payments in secure commerce and payment applications to provide security  for their communications and transactions by protecting passwords. Encryption is a fundamental tool for the protection of sensitive information. The purpose is to use encryption is privacy for preventing disclosure or confidentiality in during communications. In this paper, we proposed a new method which is based on  the Euler’s Totient  theorem  to produce a set of numbers  that  encrypt the data stream and then we used our proposed method  using  an ECC approach to generate the  signature key  which is added to encrypt data before transmission and decryption operation and  a signature  can verify at the receiver site.
