This new hardware security method preserves the unclonability and randomness of conventional PUFs while adding a key advantage: the ability to conceal the encryption key under user data and reveal it only when needed. By leveraging a controlled GIDL erase mechanism, the PUF works without any changes to the memory\u2019s circuitry or structure, enabling secure key generation and storage directly on mass-produced memory chips. Tested for stability and resistance to machine learning attacks, this practical approach could strengthen security in smartphones, cars, and IoT devices, marking a major step for data protection in the AI and big data era.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at Seoul National University have developed [&hellip;]<\/p>\n","protected":false},"author":9,"featured_media":7359,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[66],"tags":[],"class_list":["post-7358","post","type-post","status-publish","format-standard","hentry","category-66"],"_links":{"self":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/7358","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/comments?post=7358"}],"version-history":[{"count":1,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/7358\/revisions"}],"predecessor-version":[{"id":7364,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/7358\/revisions\/7364"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/media\/7359"}],"wp:attachment":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/media?parent=7358"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/categories?post=7358"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/tags?post=7358"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
