Abstract
Techniques for secure public exposure of digital data include extracting first digital data comprising one or more batches, each batch comprising a plurality of no more than a number T of packets, each packet containing a plurality of a number n of bits. A random binary matrix CK consisting of T rows and n columns is generated. For a first batch, a first random n-bit temporary key is generated and positions of the nT elements of matrix CK are randomized to produce matrix CK(RP). For a packet in the first batch, a first packet vector key is generated based on non-overlapping pairs of bit positions for both the temporary key and for a first packet-corresponding row of matrix CK(RP). An encrypted packet is generated for the packet based on the packet and the first packet vector key. The encrypted packet is exposed publicly.
