Abstract: Now a day’s mobile networks are rapid development by performing the e-commerce transaction such as online shopping, internet banking and e- payment. So that to provide secure communication, authentication and key agreement is important issue in the mobile networks. Hence, schemes for authentication and key agreement have been studied widely. So that to provide efficient and more secure techniques is necessary. In this paper we are proposed random prime order key agreement protocol proposed for authentication and key agreement. Another technique is used to provide security of transferred data using key x or data transpose technique. By using this technique we provide more security and more efficiency for transferring data.

Keywords: Mutual Authentication Security cryptography Key Aggrement.
