• Title: Redactable and Sanitizable Signature Schemes: Applications and Limitations for use in Decentralized Digital Identity Systems
• Authors: Bryan Kumara, Mark Hooper, Carsten Maple, Timothy Hobson, and Jon Crowcroft
• Abstract summary: Redactable signature schemes and sanitizable signature schemes are methods that permit modification of a given digital message and retain a valid signature. We propose implementing these protocols on a digital credential and compare them against other privacy-enhancing techniques to assess their suitability.

• Abstract: Redactable signature schemes and sanitizable signature schemes are methods that permit modification of a given digital message and retain a valid signature. This can be applied to decentralized identity systems for delegating identity issuance and redacting sensitive information for privacy-preserving verification of identity. We propose implementing these protocols on a digital credential and compare them against other privacy-enhancing techniques to assess their suitability

  We propose a method for selective disclosure and privacy-preserving revocation of digital credentials. We use second-order Elliptic Curves and Boneh-Lynn-Shacham (BLS) signatures. Our system's unique design enables extremely fast revocation checks, even with large revocation lists.

• DiVerify: Diversifying Identity Verification in Next-Generation Software Signing [6.367742522528132]
  Code signing enables software developers to digitally sign their code using cryptographic keys, thereby associating the code to their identity. Next-generation software signing such as Sigstore and OpenPubKey simplify code signing by providing streamlined mechanisms to verify and link signer identities to the public key. We introduce Diverse Identity Verification (DiVerify) scheme, which strengthens the security guarantees of next-generation software signing by leveraging threshold identity validations and scope mechanisms.

  We define and construct digital signatures with revocable signing keys from the LWE assumption. In this primitive, the signing key is a quantum state which enables a user to sign many messages. Once the key is successfully revoked, we require that the initial recipient of the key loses the ability to sign.
