Mobile agents play a key role in many researches on non-fixed services composition, but threats from potentially malicious hosts become a great obstacle of services composition based on mobile agent technology because an agent on a malicious host is in a white-box attack context. A security framework based on bilinear pairings on elliptic curves using a special digital signature technique and a multi-recipient encryption scheme is proposed. The framework provides following security features: First, verifiability, strong unforgeability and strong identifiability of digital signatures of composition member. Second, prevention of misuse of digital signatures of composition controller. Third, confidentiallity of parameters and result of services conpositon with high efficiency. All these security features relies on the difficulty of solving discrete logarithm problems and gap Diffie-Hellman problems, which are computational infeasible to solve at present.
