Abstract: The RSA key mechanism of Trusted Computing(TC) restricts encryption speed. In order to reduce time, hybrid key mechanism of data seal base on Trusted Software Stack(TSS) is proposed. The structure of TSS is introduced, the process of sealing and unsealing is illustrated and function of Trusted Platform Module(TPM) is improved. Experimental results show that the scheme can reduce the encryption time and it is suitable for encryption of mass data and can wrap data for protecting privacy efficiently with little cost.
