Wireless Networkinfrastructure has Developed Rapidly with the Popularity of Personal Mobiledevices. Userscan Use Mobile Devices to Roam the Wireless Network Environment Conductingtransactions such as Sending Messages and Accessing the Internet. Networkcommunication has Become a Lifestyle Necessity. the Application of Information Technologyproducts also Brings IT Security Issues. the Wireless Network Environment Makesmessages Susceptible to Eavesdropping and Data Tampering Attacks. in Addition,the Mobile Device Computation Ability Presents Power Limiting Issues. Therefore,achieving Efficiency and Security Requirements is more Difficult in Mobiledevice Data Transfer over a Wireless Network Compared with a Hard-Wiredcomputer Network. Insecurity Issues Abound in Peer to Peer (P2P) Networks.Conducting Identity Authentication Recognized Certified Legal Membership Andperforming Message Delivery and Shared Information are Critical Issues. Theidentity (ID) Authentication and Certification for this Type of Network Hasbecome an Important Issue. the Paperpresents a Secure Communication Method Using Self-Certified Sign-Cryption Witha Blind Signature Scheme Based on Elliptic Curve Cryptography (ECC) Forhybrid P2P Networks. Theoreticalanalysis Shows Better Secure Identification-and-Authentication Features.
