Amazon Wins Patents for Cryptography and Distributed Data Storage Solutions

E-commerce large Amazon has gained two patents associated with strategies for protecting the integrity of digital signatures and improving distributed data storage. The two patents had been printed by means of by means of the U.S. Patent and Trademark Office (USPTO) these days, Nov. 13.

The first patent document, first filed in April of this 12 months, outlines a “signature delegation” approach for “protecting the integrity of digital signatures and encrypted communications,” by means of permitting for the era, distribution, validation, and revocation of one-time-use cryptographic keys.

In the proposed machine, those keys are organized in what is understood in cryptography as a “Merkle Tree” construction, which is a binary tree of hashes made from the ground up.

As tech media platform Hackernoon outlines, Merkle Trees are a “fundamental part” of blockchain programs, as they enable for a big frame of knowledge to be successfully and securely verified:

“The Merkle Root summarizes all of the data in the related transactions, and is stored in the block header. It maintains the integrity of the data. If a single detail in any of the transactions or the order of the transactions changes, so does the Merkle Root. Using a Merkle tree allows for a quick and simple test of whether a specific transaction is included in the set or not.”

According to the newly printed patent record, Amazon’s proposed Merkle Tree-structured, encrypted machine goals to take on learn how to delegate signing authority from a central entity to the quite a lot of subordinates which might be approved to signal on its behalf.

As the patent submitting reads: “the signature authority provides a key-distribution service that distributes blocks of cryptographic keys to authorized signing delegates. An authorized signing delegate contacts the key-distribution service and requests a block of cryptographic keys.”

In instances the place a given cryptographic secret’s “marked as invalid,” after a “key revocation service queries the Merkle tree of delegable keys,” then the provider “provides the verifying entity with a revocation value associated with the revoked cryptographic key.” Amazon outlines that during some instances, the important thing revocation database could also be carried out the usage of blockchain.

Amazon’s 2nd patent, launched these days and first filed mid-Dec. 2015, pertains to problems referring to allotted information garage.

Amazon’s submitting proposes a “grid encoding technique,” the usage of teams of gathered “shards,” the place every shard represents a logical distribution of knowledge pieces saved in a given grid. The patent submitting suggests this system can assist to reduce garage redundancy, whilst permitting for most availability, sturdiness, and manner of restoration.

Notably, a number of tech startups, reminiscent of Filecoin, Sia, Storj, and Swarm have all tried to take on an identical problems with allotted information garage the usage of blockchain era, frequently mixed with cloud garage answers.

Beyond pursuing blockchain, cryptography and allotted information storage-related patents to increase its technological arsenal, Amazon has additionally filed for cryptocurrency-specific innovations. In April, Amazon Technologies used to be awarded a patent for a streaming information market that will permit customers to obtain real-time crypto transaction information.
