In a mobile client-server environment, a low-power mobile device wants to access a strong server to get some kind of services. User authentication and key establishment are two basic security requirements for this environment. Without the user authentication, an unauthorized user can access the server and gets the services. Without the key establishment, the communication between the user and the server will be disclosed. Recently, some user authentication and key establishment protocols were designed. However, all of them are homogeneous since the client and the server belong to the same cryptosystem. That is, both the client and the server belong to public key infrastructure or identity-based cryptosystem or self-certified cryptosystem. Such design does not comply with the characteristic of mobile client-server application. In this paper, we design a heterogeneous user authentication and key establishment protocol using a signcryption scheme. In this protocol, the client uses identity-based cryptosystem and the server uses the public key infrastructure. As compared with existing works, our protocol has the lowest cost in computation and communication.
