Constructing Cryptographic Accumulators from Key-Exchange Protocols

Vortrag von Diana Rauseo

Cryptographic accumulators allow membership testing in a set without disclosing the members of the set and relying on a trusted authority. This thesis provides a comprehensive exploration of cryptographic accumulators and their applications. We examine cryptographic accumulators based on the strong RSA assumptions and the trapdoor-less accumulator proposed by Nyberg and Sander. We then analyze key exchange protocols based on computational problems in groups. Our own contribution is to construct accumulators from these protocols. Finally, we discuss some of their applications such as membership testing, timestamping and their usage in cryptocurrencies.
