A Look at RSA Cryptography and the Seminal Patent that Landed the Inventors in the Hall of Fame

One of the first and most widely-used public key systems for cryptography is known as RSA cryptography, named for the trio of inventors who developed the system at the Massachusetts Institute of Technology in the late 1970s: Ronald Rivest, Adi Shamir and Leonard Adleman. These three inventors have each been inducted as part of the 2018 class of the National Inventors Hall of Fame and this Thursday, September 20th, marks the 35th anniversary of the issue of the seminal patent in the field of RSA cryptography. With this important date upon us, we return to our Evolution of Technology series to explore the development of this encryption system which has been incorporated as a fundamental aspect of many transaction systems and secure communications protocols.

How Bitcoin Became a Game Changer Overnight

Bitcoin was touted as the world’s first decentralized digital currency. It basically is a cryptocurrency which uses peer-to-peer technology to provide payment network gateway. Bitcoin is deliberately designed for public use by making it an open-source. Therefore, nobody owns or governs or control Bitcoin and everyone can be a part of it. Bitcoin financial infrastructure follows decentralized and automated systems which overcome the inefficiency of the traditional financial system. The unique feature of Bitcoin is that no one can block you from transferring money from anywhere in this world. Further, this makes whole transaction process irreversible. These transactions are recorded in a public distribution ledger called a blockchain.

U.S. Leads World in Quantum Computing Patent Filings with IBM Leading the Charge

Patenting activities in the quantum computing sector have rapidly increased in recent years, with the U.S. by far the preferred jurisdiction for applicants… One interesting finding from the Patinformatics report is that, although Northrop Grumman doesn’t have the largest portfolio in the field, it is well-situated to compete with the biggest players. “One of our main assertions is that, if there’s an organization interested in being competitive with IBM, they may want to contemplate a partnership or acquisition of Northrop Grumman,” Trippe said. Both Northrop and IBM have made significant investments into super-conducting loop qubit technologies and Northrop actually edges IBM in logic gate hardware.

The SEC Defines Blockchain, But Did They Get it Right?

The SEC has landed on a definition which includes both permissioned distributed ledgers and permissionless distributed ledgers in the term “blockchain.” This is not surprising, nor is it necessarily the result of a misinformed view. There are lots of market opportunities and reasons for enterprise permissioned distributed ledgers, as there was always market appetite for permissioned systems in general. These ventures use the term “permissioned blockchain” intentionally and purposefully. After all, the transactions are batched in blocks that are linked to each other. So, there is a chain of blocks, and some kind of consensus protocol. But is that sufficient for a blockchain, really? And what ‘blockchain’ is the SEC referring to when it references “the blockchain”?

Protecting IP in the Blockchain Sector

Blockchain technology has already disrupted the financial sector and new blockchain use cases are emerging every day — from corruption-proof land registries to licensing digital assets, to tracking individual diamonds. In fact, there are many who say that blockchain technology has the potential to be as disruptive as the Internet… To stop patent trolls, the Chamber of Digital Commerce launched the Blockchain Intellectual Property Council (BIPC) this year. BIPC’s goal is to develop a global, industry-led defensive patent strategy that will nip blockchain patent trolling in the bud. Its first meeting on March 30th attracted 40 participants. In the next meeting in April, that number rose to 70. The BIPC executive committee members are the “who’s who” list of blockchain stakeholders, including Chain, Digital Asset, IBM, Microsoft, CoinDesk, Blockstream, Bloq, Civic, Cognizant, Deloitte, Digital Currency Group, Ernst & Young, Gem, Medici Ventures,, TMX and Wipfli.

Operational Mathematics on a Processor is not an Abstract Idea

Mathematics has long been accepted as a tool to model the physical reality. For many it is hard to grasp that math actually “does something.” The reality is that mathematics based instructions in computers generate signals that are useful and used. This type of mathematics may be called “operational mathematics.” Operational math already replaces devices that used to be made from valves and gears or from electronic components. Operational mathematics also enables new devices that were previously unimaginable.
