Abstract
A method of performing an equality check in a secure system, including: receiving an input v having a known input property; splitting the input v into t secret shares vi where i is an integer index and t is greater than 1; splitting an input x into k secret shares xi where i is an integer index and k is greater than 1; splitting the secret shares xi into a s chunks resulting in s·k chunks yj where j is an integer index; calculating a mapping chain t times for each secret share vi, wherein the mapping chain including s·k affine mappings Fj, wherein yj and Fj−1(yj−1) are the inputs to Fj and the F0(y0)=vi; and determining if the outputs have a known output property indicating that the input x equals a desired value.
