The invention discloses a mobile terminal identity authentication system based on secure multi-party computing. According to an identity authentication scheme based on a digital signature and a domestic SM2 cryptographic algorithm, identity legality authentication of a mobile intelligent terminal user is realized through key management and cryptographic operation capabilities of an authenticationservice center based on hardware cryptographic equipment and a policy mechanism based on high-flux data analysis and risk control; the mobile intelligent terminal key management and password calculation risks are reduced, the system security is improved, the design complexity and implementation cost of business system risk control are reduced, and the problem that the mobile intelligent terminal performs strong identity authentication by using a password technology is solved. 本发明公开了一种基于安全多方计算的移动终端身份认证系统，基于数字签名和国产SM2密码算法的身份认证方案，通过认证服务中心基于硬件密码设备的密钥管理和密码运算能力、基于大通数据分析和风险控制的策略机制，实现对移动智能终端用户的身份合法性鉴别，消减移动智能终端密钥管理和密码计算风险，提升系统
