PURPOSE: A trusted platform module and a data management method are provided to use environment set data relevant to the trusted platform module, thereby preventing an application data operation from influencing another application program operation. CONSTITUTION: A TPM(Trusted Platform Module) receives a first command from a TSS(Trusted Software Module)(S100). If the first command uses environmental setting data, a context management unit determines whether to store environmental setting data corresponding to a first context value in a plurality of data storage units(S110,S130). A command processor processes the first command based on the first environment setting data and an integrity measurement value(S140). If data is changed, the command processor stores the changed first environmental setting data(S160,S170).
