<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

后量子安全和公共可验证凭证
简述： IOTA Identity 1.7 Beta 版确保了当前签发的凭证在未来依然安全。它引入了后量子和混合签名，以实现……

<div><div><h2>后量子安全和公共可验证凭证</h2>TL;DR： IOTA Identity 1.7 Beta 版本确保当前签发的凭证在未来依然安全可靠。它引入了与 LINKS 基金会共同开发的可验证凭证的后量子和混合签名。此外，它还添加了链上公共凭证，以提高透明度并简化密钥处理，使数字身份更加高效、互操作性，并为现实世界的采用做好准备。<adv/>未来，利用量子力学定律的计算机可能会破解当今广泛使用的公钥加密技术——保护区块链、数字身份和大多数互联网通信的加密基础。如今被认为安全的算法可能容易受到量子攻击，允许恶意行为者伪造签名、冒充身份或篡改记录。<adv/> IOTA Identity 1.7 Beta 版的发布引入了后量子密码技术，旨在保护数字凭证免受未来威胁的侵害，使其免遭威胁。这种主动防御方法意味着，今天签发的凭证可以安全保存数十年，确保今天存储的秘密在未来不会被泄露。<h3>后量子时代的安全签名</h3>通过与非营利研究中心LINKS Foundation合作，此版本带来了两种新的可验证凭证签名方法 - 无需依赖中央权威即可立即验证的数字证书。<ul><li>后量子签名基于专门为抵御量子计算机攻击而设计的算法。此版本实现了ML-DSA算法，这是美国国家标准与技术研究院 ( NIST ) 推荐的后量子密码算法。通过这种方式签名的凭证即使在后量子时代数十年后也能保持安全，从而确保数字身份的长期保护。</li><li>混合签名将传统加密算法与 ML-DSA 等后量子算法相结合。这种“两全其美”的方法既能提供强大的未来保障，又能与当今的基础设施完全兼容。使用混合签名的组织可以逐步采用后量子安全技术，而无需替换现有系统。</li></ul><h3>链上凭证</h3>到目前为止， IOTA Identity 中的可验证凭证通常是在链下私下交换的——对于个人数据来说没问题，但对于需要公开的凭证则不然。借助IOTA Identity 1.7，组织现在可以将可验证凭证直接发布到链上的公共IOTA地址。这使得凭证可以通过 DID 文档立即发现和验证，将其转变为可公开访问的证明- 使任何人都可以确认其真实性，而无需私人交换。这对于组织或产品相关的凭证（例如认证、技术规格或原产地证明）尤其有用——这些情况下透明度和广泛的可访问性至关重要。同时，由于 GDPR 等隐私法规，敏感的个人数据仍然不适合使用此功能。<h3>为什么这很重要</h3>通过这些更新， IOTA Identity 1.7 Beta 提供：<ul><li>面向未来的安全性：防御量子威胁。</li><li>平稳采用：混合签名，逐步过渡。</li><li>更高的透明度：可公开验证的链上凭证。</li></ul>这些功能共同使数字身份更加安全、更加高效，并且更适合现实世界的用例。<h3>开始</h3>IOTA Identity 1.7 Beta 现已适用于Rust 和 WASM ，并附带可立即使用的开发人员示例。如果您想开始使用这些功能，请浏览IOTA Identity 文档并加入我们的开发者社区。<hr/></div></div>

1849 年，加州淘金热，无数怀着暴富梦的人涌向美国西部。
德国移民李维·斯特劳斯原本也想加入淘金大军，但他敏锐地发现了另一个商机：矿工们的裤子经常破损，急需更耐用的工作服。
于是，他用帆布制作了一批牛仔裤，专门卖给淘金工人，从此诞生了一个名为“李维斯”的服装帝国，而当年那些真正参与淘金的人，绝大多数却血本无归。
