原文標題： Samsung develops industry’s first security chip with hardware PQC 原文連結： https://www.thelec.net/news/articleView.html?idxno=5167 發布時間： 2025.02.27 09:32 記者署名： Seok Jin Lee 原文內容： Samsung said on Tuesday that it has developed a security chip that can defend against cyber attacks from a quantum computer. The company’s System LSI Business, its logic unit, posted on its blog that its S3SSE2A was a secure element (SE) that is equipped with hardware post-quantum cryptography (PQC). S3SSE2A is a solution that will protect the most important data on smartphones, Samsung said. According to the South Korean tech giant, most SE are inside the application processor’s security block but Samsung’s new chip is a discrete secure element (DSE) that independently process security workload, save relevant data, and sends the results to the processor. This means DSE still functions while the processor is under attack, the tech giant said. Samples of S3SSE2A have already been sent to potential customers, the company added. Having the SE on the processor allows for faster data transfer speed as they are physically closer, but this means the package also becomes larger. For smartphones, which are smaller than PCs and servers, this makes the chip more complex and drives down power efficiency. Most smartphone makers have no incentive to develop DSE as they usually use processors form an outside vendor. So if they demand PQC support to Qualcomm, they will need to pay more per unit. However, Samsung manufactures its own processor and smartphones. It can put the SE inside its Exynos processor but this is costly as they have to redesign their computing subsystem so DSE has an advantage. Exynos’ CPU core is also Arm-based and putting in a logic gate for PQC on the processor is likely to be limited by licensing. Galaxy S25 supported PQC through software rather than hardware. Samsung combined its own Knox Matrix security platform with post-quantum enhanced data protection technology. Adding hardware to this will increase decryption speed even further. DSE is a complex integrated circuit comprised of a variety of components. Samsung System LSI used various component technologies from outside vendors, sources said. Meanwhile, Apple unveiled its PQ3, or post quantum 3th, protocol in February last year for iMessage security. Most chat apps have Level 0 to 1 security level but PQ3 offers Level 3 security. 心得/評論： 標題是我簡單翻譯的（有違反版規的話會自刪） 中文報導可以參考這些 https://finance.sina.com.cn/tech/digi/2025-02-26/doc-inemuvpm8947159.shtml https://statementdog.com/news/12599 之後Apple或IBM這些大廠會跟進吧！？可能屆時的資安技術應該會超越三星？ -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 36.229.9.115 (臺灣) ※ 文章網址: https://webptt.cc/bbs/Stock/M.1740631067.A.F60.html ※ 編輯: ilqgray (36.229.9.115 臺灣), 02/27/2025 12:38:48
