Current standardization efforts for cooperative Intelligent Transportation Systems both in the U.S. and Europe foresee vehicles to use a large number of changeable pseudonyms for privacy protection. Provisioning and storage of these pseudonyms require efficient and secure mechanisms to prevent malicious use of pseudonyms. In this paper we investigate several techniques to improve secure and efficient storage of pseudonyms. Specifically, we propose schemes based on Physical Unclonable Functions (PUFs) that allow to replace expensive secure key storage by regular unsecured memory and still provide fully secure pseudonyms storage.
