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.
