A secure Hybrid P2P Network mobile communication device design

摘要

Wireless network infrastructure has developed rapidly with the popularity of personal mobile devices. Users can use mobile devices to roam the wireless network environment conducting transactions such as sending messages and accessing the Internet. Network communication has become a lifestyle necessity. The application of information technology products also brings IT security issues. The wireless network environment makes messages 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 mobile device data transfer over a wireless network compared with a hard-wired computer network. Insecurity issues abound in Peer to Peer (P2P) networks. Conducting identity authentication recognized certified legal membership and performing message delivery and shared information are critical issues. The identity (ID) authentication and certification for this type of network has become an important issue. The paper presents a secure communication method using self-certified sign-cryption with a blind signature scheme based on elliptic curve cryptography (ECC) for hybrid P2P networks. Theoretical analysis shows better secure identification-and-authentication features.
