Abstract: In the cyber world, anonymous authentication is an important tool for privacy protection. However, users may misbehave under the cover of anonymity. Thus, accountability is crucial in any practical privacy-preserving authentication. Balancing anonymity and accountability has always been a challenging research problem. Accountable Anonymous credentials are the cryptographic schemes designed to address this challenge. In this talk, I will recall the concept of anonymous credentials and discuss various accountability mechanisms. Also, I will talk about its real-world applications and the challenges faced when constructing this cryptographic primitives.
