Representation and verification of data for safe computing environments and systems

A computer-implemented method for integrity verification of data in a computing device based on one or more integrity values for said data,

• wherein said computer-implemented method comprises:
• determining a number of multiple independent processing streams;
• dividing said data into said number of multiple independent processing streams for processing simultaneously and in parallel, wherein said multiple independent processing streams comprise a first data set including one or more data portions of said data in a first arrangement, and a second data set including one or more data portions of said data in a second arrangement, and wherein said first data set and said second data set are of equal or varying sizes, discrete or overlapping;
• determining a first hash value for said first data set, wherein said first hash value is based on each data portion of said first data set and said first arrangement;
• determining a second hash value for said second data set, wherein said second hash value is based on each data portion of said second data set and said second arrangement, and wherein said second hash value is determined independently from said first hash value, thereby determining two independent hash values simultaneously and in parallel;
• and
• determining, based on said first and second hash values, one or more integrity values for said data, wherein said integrity verification of said data is based on said one or more integrity values;
• wherein data partition information indicating how to divide said data into said multiple independent processing streams is generated.

A computer-implemented method for integrity verification of data in a computing device based on one or more integrity values for said data, wherein said computer-implemented method comprises:

• determining a number of multiple independent processing streams to process simultaneously and in parallel in order to generate simultaneously and in parallel multiple hash values for said data;
• dividing said data into said number of multiple independent processing streams, wherein each independent processing stream comprises a corresponding data set including one or more data portions of said data in a corresponding arrangement, and wherein data sets of said multiple independent processing streams are of equal or varying sizes, discrete or overlapping;
• process said multiple independent processing streams simultaneously and in parallel in order to generate an independent hash value for each one of said multiple independent processing streams, wherein each independent hash value for each independent processing stream is based on each data portion of a corresponding data set and a corresponding arrangement, and wherein said hash values are independent from one another;
• and
• determining, based on said hash values, one or more integrity values for said data, wherein said integrity verification of said data is based on said one or more integrity values;
• wherein data partition information indicating how to divide said data into said multiple independent processing streams is generated.
