COMMUNICATION PLATFORM INTEGRITY AND CRYPTOGRAPHY KEY ESTABLISHMENT METHOD IN INTERNET BASED COMPUTING ENVIRONMENT

摘要

PURPOSE: A method for verifying communication platform integrity and an encoding key in a internet based computing environment are provided to verify and authenticate a platform using a hardware security method. CONSTITUTION: BS(Base Station)_Verifier(200) receives a message which requests safe communication with MS_B(120) from MS_A(Mobile Station_A)(110). BS(Base Station)_Verifier verifies communication platform integrity using a TPM(Trusted Platform Module) mounted in MS_A and MS_B. If the verification is successful, BS_Verifier sets and shares an encoding key between MS_A and MS_B to enabling MS_A and MS_B to have traffic encoding communication.
