Kazu Gomi on Blockchain’s Transparency and Data Security

Blockchain’s impact goes well beyond the world of cryptocurrency. The technology itself is becoming the foundation for a new style of trust in identity, transactions, business process and human activity. Blockchain’s use of shared ledgers makes it nearly impossible to hide or forge a transaction. Call it security in plain sight, which makes good behavior …

You Know Encryption… But Do You Know What’s Coming Next?

The encryption technology that allows secure communication over the internet is several-decades old. It still works, but other approaches have emerged that improve upon the status quo. Attribute-based encryption (ABE), for instance, moves beyond the “all-or-nothing” model of the prevailing paradigm, promising greater control, efficiency and utility. This TechNewsWorld article by Hideaki Ozawa, COO/CTO at …

The Case for ABE in the IIoT

A lack of security in the industrial IoT (IIoT) can be costly. From interrupted factory lines to major disruptions in supply chains, the damage from a cybersecurity incident can be significant. Standard public key encryption (PKE) can reduce those risks. But an emerging, advanced form of PKE called attribute-based encryption (ABE) allows greater functionality, enabling …
