Certificate verification in PKI is a complex and time consuming process. In the classical PKI methodology, in order to obtain a public key and to accept a certificate as valid, a verifier needs to extract a certificate path from the PKI and to verify the certificates on this path recursively. Levi proposed a nested certificate model vvith the aim to simplify and speed up certificate verification. Such a nested certificate-based PKI significantly improves certificate verification, but it also requires a large increase in the number of issued certificates, which makes this model impractical for real life deployment. In order to solve this drawback of nested PKI, while retaining its speed in certificate verification, we propose in this paper the innovative concept of a compressed nested certificate, which is a significantly modified version of the nested certificate model. Compressed nested certificate PKI deploys compressed nested certificates which speed up and simplify certificate verification while keeping certificate load to a minimum, thus providing implementers the option of integrating it into the existing PKI model or building it separately as an independent model.
