Public key infrastructure (PKI) is considered as a key element for providing security to new distributed communication networks and services. In this paper, we concentrate on the properties of the protocol of Phase 1 IKE. After investigating IKE protocol and PKI technology, we combine IKE protocol and PKI and present an implementation scheme of the IKE based on PKI. Then, we give a logic analysis of the proposed protocol with the BAN-logic and discuss the security of the protocol. The result indicates that the protocol is correct and satisfies the security requirements of Internet key exchange.展开更多

Its need and use has grown over the years and continually grows. This research work examines the current PKI framework’s validation process as operated by vendors and subscribers to identify the drawbacks and propose enhanced approaches to its validation mechanism. Using an approach of reviewing secondary data, critical weaknesses of integrity, proof of trust and single point-of-failure were identified with the current PKI framework. This study therefore advances proposed solutions to address the identified weaknesses by specifically introducing multiple Certificate Authorities, storage, visibility and searchability of subscriber information in public repository. A comprehensive detail of its implementation is proposed to address the identified weaknesses of uncertain integrity, trust for certificate authorities and prevent a single point of failure. Furthermore, the proposed enhancements are validated with the protection motivation theory and a framework for empirically testing the enhancements is suggested. Further research would be required to factor in multi-factor authentication without compromising performance.展开更多

In order to solve this problem, the paper first puts forward the security architecture of manufacturing grid on the basis of the proposal of the security strategies for manufacturing grid; then the paper introduces key technologies based on public key infrastructure-certificate authority （PKI/CA） to ensure the security of manufacturing grid, such as single sign-on, security proxy, independent authentication and so on. Schemes discussed in the paper have some values to settle security problems in the manufacturing grid environment.展开更多

This paper also proposes a mechanism that can secure thecommunication between the current mobile terminals and the Internet Web Server. Yield to thecapabilities of the current mobile terminals, the public key techniques cannot be used now. But inthe future, the memory space and the computation ability of the mobile terminals will no longer beany puzzles, so certificate and Public Key Infrastructure (PKI) can be used to make wirelesscommunication security. This paper also proposes PKI architecture in the future mobile network.Finally this paper makes an assumption of the network's development and its secure issues.展开更多
