Abstract

We formally study two privacy-type properties for online auction protocols: bidding-price-secrecy and receipt-freeness. These properties are formalised as observational equivalences in the applied π calculus. We analyse the receipt-free auction protocol by Abe and Suzuki. Bidding-price-secrecy of the protocol is verified using ProVerif, whereas receipt-freeness of the protocol is proved manually.
