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
