ePrint Report: Cryptographic Accumulators: New Definitions, Enhanced Security, and Delegatable Proofs

Anaïs Barthoulot, Olivier Blazy, Sébastien Canard

Cryptographic accumulators, introduced in 1993 by Benaloh and De
Mare, represent a set with a concise value and offer proofs of (non-)membership. Accumulators have evolved, becoming essential in anonymous credentials, e-cash, and blockchain applications. Various properties like dynamic and universal emerged for specific needs, leading to multiple accumulator definitions. In 2015, Derler, Hanser, and Slamanig proposed a unified model, but new properties, including …
