In this paper, we present k-rAC, a fine-grained access control for DHTs. It allows to specify and enforce different access rights for each individual data item in the presence of attackers and up to $k$ subverted participants. Our approach can be tailored towards different thread levels and usage scenarios by adapting k and by choosing one of three authentication mechanisms that we provide. %@ 978-1-4503-5257-4/17/08
