Efficient and Privacy-Preserving Certificate Activation for V2X Pseudonym Certificate Revocation

QuasiModo: Efficient Certificate Validation and Revocation

We present two new schemes for efficient certificate revocation. Our first scheme is a direct improvement on a well-known tree-based variant of the NOVOMODO system of Micali [11]. Our second scheme is a direct improvement on a tree-based variant of a multi-certificate revocation system by Aiello, Lodha, and Ostrovsky [1]. At the core of our schemes is a novel construct termed a QuasiModo tree, ...

Efficient Certificate Revocation : A P2P Approach

Certificate revocation is one of the many challenges faced by Public Key Infrastructure (PKI). Certificate revocation is the action of declaring a certificate, which has not expired, is no longer valid due to various reasons ranging from change of relationship between certificate issuer and the public key owner to compromised private keys of the associated certificate to change of information c...

Windowed Certificate Revocation

The advent of electronic commerce and personal communications on the Internet heightens concerns over the lack of privacy and security. Network services providing a wide range of security related guarantees are increasingly based on public key certificates. A fundamental problem inhibiting the wide acceptance of existing certificate distribution services is the lack of a scalable certificate re...

Certificate Revocation Paradigms

With the extensive development of applications of public key cryptography, the need for supporting infrastructure arose. It became clear that a person can not just use another person’s public key obtained in some way, but he also has to be sure that the key and its claimed owner really belong together and that the connection is not expired. One of the oldest and most widespread ideologies to sa...
