        Abstract:        Chaos theory has been widely studied and adapted in cryptography for achieving some security mechanisms, such as encryption/decryption, key agreement and hash function. In order to improve the scope of application, many recearchers consider that chaos theory should be used in telecare medicine platform. Telecare Medicine Information Systems (TMISs) is a new emerging thing which aims at constructing a communicating platform supporting the patients access health-care delivery services via internet or mobile networks. Recently, Lu et al. proposed a secure smart card based authentication scheme for TMISs using enhanced chaotic maps. In this paper, we show that Lu et al. s scheme has still some weaknesses such as smartcard denial of access, using XOR operation in a wrong way and some other flaws. Then, we give an improved scheme to revise these flaws. Finally, BAN logic proof and efficiency comparison are provided to show that our scheme is secure and more practical for telemedical environments. © 2016, Ubiquitous International.
