As the joke goes, CRQC has been 10 to 20 years away for the past three decades. While the recent research suggests that ...

Your Email is Encrypted Today, but Will It Hold Up Tomorrow? Awakening one day to discover that every “secure email” you’ve ever written was not secure at all. Your client contracts, financial ...

サイバー犯罪者のマーケティング戦略： サイバー犯罪者はソーシャルメディアに活動拠点を拡大、RSAが調査結果を公開 EMCジャパンのRSA事業本部は、インターネットを利用するサイバー犯罪者がソーシャルメディアを利用している実態についての調査結果を公開した。サイバー犯罪者は、ソーシャルメディアの特性を狙っていると警鐘を鳴らす。（2018/5/24） ...

Traditionally, enterprises have embedded cryptographic choices deep within applications and hardware appliances. When vulnerabilities arrive, whether due to newly discovered flaws in an algorithm or ...

One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.

In February, a research team published a new architecture showing that RSA-2048, the encryption standard underpinning most of the internet’s security, could be broken with fewer than 100,000 physical ...

Online data is generally pretty secure. Assuming everyone is careful with passwords and other protections, you can think of it as being locked in a vault so strong that even all the world’s ...

You gotta build a "digital twin" of the mess you're actually going to deploy into, especially with stuff like mcp (model context protocol) where ai agents are talking to data sources in real-time.

Last summer saw security giant Palo Alto Networks update its firewall operating system with quantum-optimized hardware to ...

More than half the traffic on Cloudflare is already secure against the threat of harvest-now/decrypt-later using ML-KEM ...

筆者のように歳を取ると、原理や理論の提唱から実用化までの経過を見ることがある。量子コンピュータは1981年（大学生の頃）のリチャード・ファインマンが提唱した。最初に計算を行ったのは1998年のNMR（Nuclear Magnetic ...

東芝は、量子コンピューターの仕組みをまねて複雑な組み合わせ最適化問題を古典コンピューターで高速に解く「疑似量子計算」のアルゴリズムを飛躍的に進化させた。最新の第３世代版を用いて、限られた試行回数で最適解の推定値に到達する成功確率を第２世代の数％から約 ...
