With the existing anonymous authentication schemes based on biometrics,the user and the server can create the same session key after mutual authentication.If the anonymous authen-tication scheme is applied in the electronic medical environment,it is also necessary to consider that the patient may access multiple hospital servers.Based on three factors of smart card,random number and biometrics,an anonymous authentication scheme in the electronic medical environment is proposed.In order to reduce the burden of the medical registration and certification center(HC),in the proposed anonymous authentication scheme,the patient only needs to register with HC once,then he/she can apply for visiting each hospital that has joined the medical servers.Security analysis shows that the proposed scheme has anonymity and dual authentication,and can resist various types of attacks,such as insider attack,modification attack,replay attack and smart card loss attack.Efficiency analysis shows that the calculation cost of the proposed scheme in the registration and login phase is lower,and it is slightly higher than Lei's scheme and Khan et al's scheme in the authentication phase.The proposed scheme can not only resist various types of attacks,but also support dual authentication and multi-server environment.With a little modification,the pro-posed scheme can also be used to other application scenarios re-quiring anonymous authentication.
