Public-Key Management

Show Summary Details

Preview

This chapter builds on the previous one by considering additional key management issues that arise for management of public-key pairs. We identify why management of public keys presents special challenges and then consider different approaches to addressing these issues. We consider certification of public keys and examine the different stages in the lifecycle of a public-key certificate, paying particular attention to the creation and revocation of public-key certificates. In doing so, we investigate that it means to rely on a public-key certificate and what issues can arise with the deployment of public-key management infrastructures that are based on public-key certificates. We close by considering some alternative public-key management models that do not rely on public-key certificates.

Keywords: Public-key infrastructure; Public-key certificate; Digital certificate; Certificate revocation; Web of trust; Identity-based encryption
