Single sign-on (SSO) has provided convenience to users in the web domain as it can authorize a user to access various resource providers (RPs) using the identity provider (IdP)'s unified authentication portal. However, SSO also faces security problems including IdP single-point failure and the privacy associated with identity linkage. In this paper, we present the initial design of an alternative SSO solution called VC-SSO to address the security and privacy problems while preserving SSO's usability. VC-SSO leverages the recently emerged decentralized identifier (DID) and verifiable credential (VC) framework in that a user only needs to authenticate with the IdP once to obtain a VC and then may generate multiple verifiable presentations (VPs) from the VC to access different RPs. This is based on the design that each RP has established a smart contract with the IdP specifying the service agreement and the VP schema for user authorization. We hope the proposed VC-SSO design marks the first step toward a future SSO system that provides strong reliability and privacy to users under adversarial conditions.
