Recently， Chang et al。 proposed an authentication and key agreement protocol for satellite communications， and they claimed that their scheme could withstand various attacks。 However， in this paper， we will show that their scheme is vulnerable to the denial of service attack and the impersonation attack。 Moreover， we also point out that the adversary could compute the session key through the intercepted message。 The analysis shows the scheme of Chang et al。 is not secure for practical applications。 Copyright (c) 2013 John Wiley & Sons， Ltd。
