Abstract

Certificate authority is the core component of public key infrastructure. However, the traditional structure of CA is either hierarchical or reticular, unsuitable for the security requirements of the new trends in enterprise cooperation, namely the virtual enterprise (VE). In this paper a new idea, the virtual certificate authority (VCA), is proposed, as well as its implementation. The goal of VCA is to provide a certificate service over virtual enterprises while keeping the CA of each participant intact as much as possible. Unlike PEM, PGP, and BCA, by using the secret sharing scheme, virtual CA avoids the need for TTP and supports the virtual enterprise´s feature of dynamical construction and destruction
