Abstract
A method for producing linkage values to be contained within pseudonym digital certificates of a security credential management system for connected vehicles, including the following steps: providing a linkage value function that expresses linkage values as a function of a number of input parameters that include a linkage seed input from a pseudonym certificate authority processor entity and a plurality of inputs from a registration authority processor entity including a vehicle identifier and at least one index relating to a time period for the linkage value; producing a Boolean circuit representative of the function for a particular combination of the number of input parameters; and executing a garbled circuit protocol on the Boolean circuit between the registration authority processor entity and the pseudonym certificate authority processor entity, whereby the pseudonym certificate authority processor entity privately derives a linkage value for the particular combination of the number of input parameters.
