Abstract
A plurality of objects that comprise an input to a cryptographic signing function. For each object in the plurality of objects, an output value yof a hash function is calculated, where the value i is equal to an index value of the object, a compressed output value xof a compression function is calculated, the output value yfrom the computer readable memory, and the compressed output value xis stored. For each object in the plurality of objects, an output value y'of the hash function is calculated, where the value i is equal to the index value of the object, a compressed output value x′of the compression function executed on the output value y′is calculated, the output value x′is determined to be equal to the output value x, and the output value y′is transmitted in an output data stream.
