Registered Attribute-Based Signature
Abstract
This paper introduces the notion of registered attribute-based signature (registered ABS). Distinctly different from classical attribute-based signature (ABS), registered ABS allows any user to generate their own public/secret key pair and register it with the system. The key curator is critical to keep the system flowing, which is a fully transparent entity that does not retain secrets. Our results can be summarized as follows.
-This paper provides the first definition of registered ABS, which has never been defined.
-This paper presents the first generic fully secure registered ABS over the prime-order group from
