Explore How IOTA Identity Is Revolutionizing Privacy With Zero Knowledge Credentials
Collaborative Enhancements in Digital Identity Management
Exploring New Frontiers with LINKS Foundation
Overview
The IOTA Foundation, in collaboration with its steadfast partner, the LINKLearning Foundation, is advancing the frontier of digital privacy through the introduction of privacy-centric selective disclosure credentials within IOTA Identity. This innovation offers users the flexibility to share selective information from their credentials at their discretion.
Recent Developments in Selective Disclosure Technology
In a pivotal development as of October 2023, the Cybersecurity Research Group at LINKS Learning Foundation unveiled their ZKryptium library. This library is pivotal for the development of zero-knowledge selective disclosure credentials aimed to be integrated into IOTA Identity. Both entities have since joined efforts to implement these privacy-preserving tools effectively for users of the IOTA digital identity framework.
Furthermore, LINKS Learning Foundation has become a member of the Identity Working Group, a consortium committed to the widespread adoption of self-sovereign identity (SSI) facilitated by IOTA Identity technologies.
Unpacking the Role of the Identity Working Group
Initiated in July 2023, the Identity Working Group includes founding organizations such as walt.id, Teleconsys, TangleLabs, Impierce Technologies, Filancore, and Demia, alongside prominent members like TLIP and the IOTA Foundation. Their collective goal is maintenance and enhancement of the IOTA Identity Library, setting the stage for significant advancements in digital identity solutions.

Insights into LINKS Learning Foundation
As a newly inducted member of the Identity Working Group, LINKS focuses on bridging innovative research with pragmatic market applications, particularly in cybersecurity and digital identity realms. Their role in leading EU-funded projects like QUBIP, which explores post-quantum cryptography’s impact on digital protocols, underscores their pivotal role in advancing security technologies.
The Mechanics and Benefits of SSI and Selective Disclosure
At its core, the Identity Working Group’s principle focus is on SSI, empowering individuals to manage their data through robust cryptographic proofs. Selective disclosure elevates this concept by allowing the sharing of specific elements of a credential — for instance, sharing a date of birth for age verification purposes while keeping other sensitive data like addresses confidential. This functionality not only limits the verifier’s access to necessary information but also upholds the authenticity of the credential.
Practical Applications of Selective Disclosure
SSI’s adaptability manifests in various selective disclosure methods, from advanced cryptographic approaches to simpler hashing techniques. Each method ensures that only essential attributes are visible to verifiers, thus maintaining data privacy and origin authenticity.
Currently, IOTA Identity’s library supports two selective disclosure implementations: The Selective Disclosure JSON Web Token (SD-JWT) and BBS+-based Selective Disclosure.
Understanding SD-JWT
SD-JWT affords issuers the control to determine disclosable fields in a credential. It involves masking certain fields with cryptographic hashes or decoy texts to prevent predictability by malicious entities. The recent addition of SD-JWT in the IOTA Identity library aligns with the eIDAS 2.0 regulations, prioritizing user privacy without relying on experimental cryptography.
The Advancements in BBS+-based Selective Disclosure
In contrast, BBS+ credentials do not require pre-defined disclosures. This model, derived from the foundational principles set by Camenisch, Kohlweiss, and Soriente, offers users unparalleled flexibility and privacy by enabling them to determine disclosure arrangement dynamically. The recent introduction of BBS+-based credentials in the IOTA Identity library indicates a move towards more sophisticated, privacy-focused digital identity management.
Forging Ahead: The Roadmap for IOTA Identity
As IOTA continues to collaborate with the LINKS Foundation, the trajectory includes further enhancements to both SD-JWT and BBS+-based disclosures, continuously refining these tools to meet evolving user and verifier needs. This exploration is poised to enhance privacy features and streamline processes, ensuring that digital identity systems are both robust and user-centric.
