Trusted Software Construction Model Based on Trust Shell

Due to not considering the guaranty of trustiness, traditional software development methods and techniques lack effective measures for ensuring trustiness. Combining agent technique with trusted computing provided by TPM, a trusted software construction model based on Trust Shell (TSCMTS) is demonstrated in this paper, where Trust Shell is responsible for ensuring the trustiness of software logically. In particular, for the purpose of improving the accuracy of trustiness constraints, a strategy of determining multiple attributes' weights by information entropy for check point is proposed. Both simulation experiment results and practical application indicate that the TSCMTS is of effective trustiness and reasonable performance overhead.
