Abstract To provide secure roaming services for mobile users in Global Mobility Networks, many schemes have been proposed recent years. However, most of them focus only on authentication and fail to satisfy practical security requirements such as user anonymity untraceability. address this problem, we propose a privacy‐preserving scheme based elliptic curve cryptography. The is provably under formal model that satisfies all requirements. Compared with existing schemes, ours enjoys better performance terms computation cost security.
