The idea of shared certificates is to assign each certificate to a large enough group of vehicles so that it will be difficult for adversaries to link a certificate to any particular vehicle. This chapter focuses on statistically shared certificates. That is, a certificate is assigned to each vehicle according to a probability distribution so that a random group of vehicles shares each certificate. The chapter first discusses the properties and limitations of the original combinatorial certificate scheme. It discusses the potential solutions to improve the scalability and robustness of statistical certificate sharing. When a certificate assigned to a misbehaving vehicle is revoked, all the other vehicles sharing this certificate will also not be able to use it. This effect is referred to as certificate revocation collateral damage. Certified interval is a crucial indicator of a certificate scheme’s robustness. robust control
