Assertions for Optional Features - Hidden Sector (HS) Assertion ID TSP- AHS-01 TSP- AHS-02 TSP- AHS-03 Assertion Description The tool reports to the user if any hidden sectors are found The tool reports to the user that digital source may contain hidden sector but unable to detect it due to incompatible execution environment and/or access interface. The tool reports to the user that hidden sectors will not be acquired if the tool is unable to acquire hidden sectors due to incompatible execution environment and/or access method. Assertions for Optional Features - Image Creation (IC) Function 141 Correspondent Assertion (Byers & Shahmehri, 2009) SKL-DIA-08 SKL-DIA-09 SKL-DIA-10 SKL-DIA-11 SKL-DIA-12 Assertion ID Assertion Description Corresponden t NIST Assertion TSP-AIC-01 The data represented by an image file is the same as the data acquired by the tool DA-AO-01 TSP-AIC-02 The tool creates an image file according to the file format the user specified. DA-AO-02 TSP-AIC-03 The tool reports to the user if an error occurs during the image creation process. The tool reports to the user if insufficient space in DA-AO-03 TSP-AIC-04 the destination device during the image creation process. If multi-file image creation and the image file size DA-AO-04 TSP-AIC-05 is selected, the tool creates a multi-file image except that one file may be smaller If the image file integrity check is selected, the tool DA-AO-05 TSP-AIC-06 shall report to the user the image file has not been changed if the image file has not been changed. If the image file integrity check is selected, the tool DA-AO-06 TSP-AIC-07 shall report to the user the image file has been changed if the image file has been changed. If the image file integrity check is selected, the tool DA-AO-07 TSP-AIC-08 shall report to the user the image file has been changed and the involved location if the image file has been changed. DA-AO-08 TSP-AIC-09 If image format conversion is selected, the target DA-AO-09
TSP-AIC-10 TSP-AIC-11 image file format contains the same data as the original image file The tool reports to the user if insufficient space in the destination device to contain the multi-image file creation and if destination device switching function is supported, the image is continue on the selected destination device. The tool reports to the user if any irregularities found in the digital source. 142 DA-AO-10 SKL-DIA-24
