Zusk is a Zero-Knowledge Know Your Customer (KYC) protocol designed specifically for eSIM providers and telecom network providers. It aims to verify the validity of users while preserving their privacy and maintaining compliance with KYC requirements. Zusk leverages zero-knowledge cryptographic algorithms to create a ZK identity for end users, enabling them to undergo KYC checks through a zero-knowledge proof protocol.
Roles of Different Personas:
a. End User/Customer: Registers and submits personal information with the IdP. Receives a ZK identity and digital credentials. Uses ZK identity to generate zero-knowledge proofs when interacting with service providers.
b. Identity Provider (IdP): Processes end user's personal information and performs initial KYC. Generates a ZK identity and digital credentials for the end user. Stores encrypted representations of the user's data securely. Provides public information to service providers for proof verification.
c. eSIM Providers and Telecom Network Providers (Service Providers): Implement the Zusk protocol to support zero-knowledge proofs. Receive and verify zero-knowledge proofs submitted by end users. Provide services (e.g., eSIM activation) to users after successful authentication. Zusk Protocol Workflow The Zusk protocol workflow can be summarized in the following steps:
a. User Enrollment: The end user registers with the IdP and submits personal information. The IdP performs the necessary KYC checks and generates a ZK identity and digital credentials for the user.
b. Zusk Protocol Integration: Service providers (e.g., eSIM providers and telecom network providers) integrate the Zusk protocol to support zero-knowledge proofs.
c. User Authentication:
The end user generates a zero-knowledge proof using their ZK identity and digital credentials. The end user submits the zero-knowledge proof to the service provider (e.g., Airalo) as part of the authentication process. The service provider verifies the proof using the public information provided by the IdP and the Zusk protocol. If the proof is successfully verified, the service provider proceeds with providing the requested service (e.g., eSIM activation).
By implementing the Zusk protocol, eSIM providers and telecom network providers can offer a privacy-preserving and secure KYC process to their customers while maintaining compliance with regulatory requirements. This approach allows users to authenticate their identity without exposing sensitive personal information, ensuring a higher level of privacy and security.
