Identity recognition method, system, dynamic token, mobile terminal and gateway device

The invention provides an identity recognition method and system and a dynamic token, a mobile terminal, a gateway device. The mobile terminal acquires a first password, the first password is one-timeinformation and is used for verifying the identity of the mobile terminal, and the mobile terminal sends an access request to the gateway device, the access request carries the first password, and the gateway device acquires the access request to verify the first password, and after the verification is passed, the mobile terminal accesses an intelligent device. According to the invention, the identity authentication of the mobile terminal to the intelligent device is realized, the safety is ensured, and the user experience is improved. 本发明提供了种身份识别方法、系统及动态令牌、移动终端、网关设备，移动终端获取第口令，第口令为次性信息，用于对移动终端的身份进行验证，移动终端向网关设备发送访问请求，访问请求中携带第口令，网关设备获取访问请求，对第口令进行验证，在验证通过后，移动终端对智能设备进行访问。通过本发明的实施，实现了移动终端访问智能设备的身份认证，保证了安全性，提升了用户体验。
