Abstract
We propose a secure authentication scheme between users and the server in telecare medicine information system. In mobile telecare medicine information system, because of lower computation mobile devices, user authentication has been addressed efficiently. The major difference between our scheme and other schemes is the pre-computing phase. Obviously, our scheme is based on the hash function and discrete logarithms problem, so it has the same security level as other schemes. But we use the pre-computing phase to avoid the high cost of exponential operation. Therefore, it is very suitable for low computation mobile devices in telecare medicine information system, such as PDA.
