Abstract: Mobile agent is widely used in distributed parallel computing, network information search, e-commerce and other fields, but the security issue has been an important reason to hinder its development. In this paper a new route detecting protocol is proposed to protect mobile agent using signatures combining with onion itinerary technology and Identity-Based Encryption. The detection process without mutual consultation not only saves network bandwidth, but also speeds up the encryption and decryption speed. The protocol based on identity-based encryption avoids the complexity of identity in the public key infrastructure certificate management and improves operational efficiency.

摘要： 移动代理目前广泛应用于分布式并行计算、网络信息搜索、电子商务等领域，但安全问题一直是阻碍其发展的重要原因。结合身份密码学知识和洋葱路由工作原理提出了一种新型的非交互式移动代理路径检测协议，检测过程中无需双方协商，既节省了网络带宽，又加快了加解密速度。基于身份的加密也避免了公钥基础设施中身份证书的复杂管理，提高了系统运作效率。
