<h2>Post-Quantum Security and Public Verifiable Credentials</h2>
TL;DR: IOTA Identity 1.7 Beta ensures credentials issued today stay secure in the future. It introduces post-quantum and hybrid signatures for Verifiable Credentials, developed with the LINKS Foundation. It also adds on-chain public credentials for transparency and streamlined key handling, making digital identity more efficient, interoperable, and ready for real-world adoption.
<adv/>In the future, computers that use the laws of quantum mechanics could break much of today’s widely used public-key cryptography – the cryptographic foundation that secures blockchains, digital identities, and most internet communications. Algorithms considered secure today could be vulnerable to quantum attacks, allowing malicious actors to forge signatures, impersonate identities, or alter records.
<adv/>The release of the 1.7 Beta version of IOTA Identityintroduces post-quantum cryptography to protect digital credentials from these future threats before they become a reality. This proactive approach means that credentials issued today could remain secure for decades, ensuring that secrets stored today won’t be unveiled in the future. 
<h3>Secure Signatures for a Post-Quantum Era</h3>
In collaboration with the non-profit research center LINKS Foundation, this release brings two new signature methods for Verifiable Credentials – digital certificates that can be instantly verified without relying on a central authority.
<ul>
<li>
Post-Quantum Signatures are built on algorithms specifically designed to resist attacks from quantum computers. This release implements ML-DSA, an algorithm recommended by NIST(the US National Institute of Standards and Technology) for post-quantum cryptography. Credentials signed this way are designed to remain secure even decades into a post-quantum future, ensuring long-term protection for digital identities.</li>
<li>
Hybrid Signatures combine traditional cryptographic algorithms with post-quantum algorithms like ML-DSA. This “best of both worlds” approach offers strong future-proofing while maintaining full compatibility with today’s infrastructure. Organizations using hybrid signatures can begin adopting post-quantum security gradually, without replacing their existing systems.
</li>
</ul>
<h3>On-Chain Credentials</h3>
Until now, Verifiable Credentials in IOTA Identity were typically exchanged privately off-chain – fine for personal data, but not for credentials that benefit from being publicly available.
With IOTA Identity 1.7, organizations can now publish Verifiable Credentials directly on-chain to a public IOTA address.
This makes Credentials instantly discoverable and verifiable through a DID Document, turning them into publicly accessible proofs – enabling anyone to confirm their authenticity without needing a private exchange.
This is especially useful for organizational or product-related credentials such as certifications, technical specifications, or proofs of origin — cases where transparency and broad accessibility matter. At the same time, sensitive personal data remains unsuitable for this feature due to privacy regulations like GDPR.
<h3>Why This Matters</h3>
With these updates, IOTA Identity 1.7 Beta offers:
<ul>
<li>
Future-proof security: Protection against quantum threats.</li>
<li>
Smooth adoption: Hybrid signatures for gradual transition.</li>
<li>
Greater transparency: Publicly verifiable on-chain credentials.</li>
</ul>
Together, these features make digital identity more secure, more efficient, and better suited for real-world use cases.
<h3>Get Started</h3>
IOTA Identity 1.7 Beta is available today for bothRust and WASM, with ready-to-use developer examples.

IOTA Identity 1.7 Beta

後量子安全和公共可驗證憑證
簡述： IOTA Identity 1.7 Beta 版確保了當前簽發的憑證在未來依然安全。它引入了後量子和混合簽名，以實現……

<div><div><h2>後量子安全和公共可驗證憑證</h2>TL;DR： IOTA Identity 1.7 Beta 版本確保當前簽發的憑證在未來依然安全可靠。它引入了與 LINKS 基金會共同開發的可驗證憑證的後量子和混合簽名。此外，它還添加了鏈上公共憑證，以提高透明度並簡化密鑰處理，使數字身份更加高效、互操作性，併為現實世界的採用做好準備。<adv/>未來，利用量子力學定律的計算機可能會破解當今廣泛使用的公鑰加密技術——保護區塊鏈、數字身份和大多數互聯網通信的加密基礎。如今被認為安全的算法可能容易受到量子攻擊，允許惡意行為者偽造簽名、冒充身份或篡改記錄。<adv/> IOTA Identity 1.7 Beta 版的發佈引入了後量子密碼技術，旨在保護數字憑證免受未來威脅的侵害，使其免遭威脅。這種主動防禦方法意味著，今天簽發的憑證可以安全保存數十年，確保今天存儲的秘密在未來不會被洩露。<h3>後量子時代的安全簽名</h3>通過與非營利研究中心LINKS Foundation合作，此版本帶來了兩種新的可驗證憑證簽名方法 - 無需依賴中央權威即可立即驗證的數字證書。<ul><li>後量子簽名基於專門為抵禦量子計算機攻擊而設計的算法。此版本實現了ML-DSA算法，這是美國國家標準與技術研究院 ( NIST ) 推薦的後量子密碼算法。通過這種方式簽名的憑證即使在後量子時代數十年後也能保持安全，從而確保數字身份的長期保護。</li><li>混合簽名將傳統加密算法與 ML-DSA 等後量子算法相結合。這種“兩全其美”的方法既能提供強大的未來保障，又能與當今的基礎設施完全兼容。使用混合簽名的組織可以逐步採用後量子安全技術，而無需替換現有系統。</li></ul><h3>鏈上憑證</h3>到目前為止， IOTA Identity 中的可驗證憑證通常是在鏈下私下交換的——對於個人數據來說沒問題，但對於需要公開的憑證則不然。藉助IOTA Identity 1.7，組織現在可以將可驗證憑證直接發佈到鏈上的公共IOTA地址。這使得憑證可以通過 DID 文檔立即發現和驗證，將其轉變為可公開訪問的證明- 使任何人都可以確認其真實性，而無需私人交換。這對於組織或產品相關的憑證（例如認證、技術規格或原產地證明）尤其有用——這些情況下透明度和廣泛的可訪問性至關重要。同時，由於 GDPR 等隱私法規，敏感的個人數據仍然不適合使用此功能。<h3>為什麼這很重要</h3>通過這些更新， IOTA Identity 1.7 Beta 提供：<ul><li>面向未來的安全性：防禦量子威脅。</li><li>平穩採用：混合簽名，逐步過渡。</li><li>更高的透明度：可公開驗證的鏈上憑證。</li></ul>這些功能共同使數字身份更加安全、更加高效，並且更適合現實世界的用例。<h3>開始</h3>IOTA Identity 1.7 Beta 現已適用於Rust 和 WASM ，並附帶可立即使用的開發人員示例。如果您想開始使用這些功能，請瀏覽IOTA Identity 文檔並加入我們的開發者社區。<hr/></div></div>

1849 年，加州淘金熱，無數懷著暴富夢的人湧向美國西部。
德國移民李維·斯特勞斯原本也想加入淘金大軍，但他敏銳地發現了另一個商機：礦工們的褲子經常破損，急需更耐用的工作服。
於是，他用帆布製作了一批牛仔褲，專門賣給淘金工人，從此誕生了一個名為“李維斯”的服裝帝國，而當年那些真正參與淘金的人，絕大多數卻血本無歸。
2024 年 11 月 20 日，英偉達英偉達又一次交出“逆天”的財報。
