Abstract
A method is disclosed. The method comprises a receiving a plurality of key-value pairs. The method then generates a random binary matrix of at least weight three. The random binary matrix has a number of non-zero binary values equal to the weight in each row. The method can then assign each key in the plurality of key-value pairs to a row in the random binary matrix. A key matrix can then be generated by appending a dense binary matrix to the random binary matrix. The method can then process the key matrix to output an encoding vector that encodes the values of the plurality of key-value pairs.
