  • Obfuscating programs using matrix tensor products
    Patent number: 10936703
    Abstract: A method for compiling a matrix-product program into an obfuscated-matrix-product program includes receiving a plurality of matrices that form the matrix-product program, randomly generating a set of independent and invertible tensor-product matrices, randomly generating a set of independent and invertible linear-transform matrices, and generating a dynamic-fence-generation gadget by processing at least one of the plurality of matrices, the set of tensor-product matrices and the set of linear-transform matrices. The dynamic-fence-generation gadget is an obfuscated version of computer program represented by the plurality of matrices.
