In Kazuhiro Gomi’s latest Forbes article, he reviews the time-stamping origins of blockchain and points to smart contracts as a barometer of blockchain’s viability outside of the cryptocurrency realm. He also notes that blockchain is a work in progress. Academics are identifying theoretical weaknesses and pointing out ways to increase its efficiency. And many of

How close is quantum computing to threatening existing cryptosystems? Where do we stand on the development of defenses? And what can we do now? The good news is that the kind of quantum computing that could pose a threat is not close to the required scale and that there are viable post-quantum candidates. The bad

Few people know much about cryptography. What the public learns, from headlines and advertisements that often exploit those headlines, is that existing cryptosystems seem to break fairly often. In his latest article for Forbes, NTT Research President and CEO, Kazuhiro Gomi, points to three counter examples of cybersecurity actually tightening: 1) a breakthrough in “indistinguishability

By NTT Research CIS Lab In cryptography, well-founded assumptions are generally preferable to clever or especially hard ones. This may sound counter-intuitive, but the weaker and more well-founded the assumption, the more believable the outcome. In that light, one popular cryptographic concept, indistinguishability obfuscation (iO), found itself in trouble. According to the authors of a
