I am a newbie in cryptography (I know the basic RSA, AES stuffs) and am interested in anonymous authentication systems. Looks like David Chaum is the godly figure in the field. I see lots of people citing his anonymous credential system paper and his paper.
Can someone explain in simple language (and simple maths), the concept behind David Chaum's anonymous credential system? I find the papers too heavy to understand. I probably have lots of follow up questions.
