Smart contracts, (blockchains, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Patents. Assigned to Wells Fargo Bank, the first patent addresses techniques for post-quantum cryptography optimization. The second Wells Fargo patent addresses techniques for post-quantum cryptography side chains.

Abstract
Systems, apparatuses, methods, and computer program products are disclosed for post-quantum cryptography (PQC). An example method includes receiving data. The example method further includes generating a set of data attributes about the data. The example method further includes generating a data envelope based on the set of data attributes. Subsequently, the example method includes generating an enveloped data structure based on the data envelope and the data.

Abstract
A computing entity accesses one or more blocks of a blockchain, encrypts the content of the one or more blocks using a first cryptographic technique to generate one or more first encrypted block values, and writes a first side chain block comprising the one or more first encrypted block values and a first signature to a first side chain. The computing entity accesses at least one of (a) at least one block of a particular second set of one or more second sets of the plurality of blocks or (b) one or more first side chain blocks corresponding to blocks of the second set, encrypts the content of the accessed block(s) using a second cryptographic technique to generate at least one second encrypted block value, and writes a second side chain block comprising the at least one second encrypted block value and a second signature to a second side chain.
