This is one of the question asked in my class. Implement a anonymous digital signature. So it means hiding signers information. i could not find any article in anonymous digital signing. Also another confusion made me think about blind signature. blind signature used to hide senders information before sign by a third party. This scheme is not going to hide sender identity. For my knowledge group signature can be used hide the identity of sender. My question is
- what is anonymous digital signature
- How it different from blind signature
- How can we use this to hide identity of sender
