Practical and secure trust anchor management and usage

Carl Wallace, Geoff Beier
2010 Proceedings of the 9th Symposium on Identity and Trust on the Internet - IDTRUST '10  
Public Key Infrastructure (PKI) security depends upon secure management and usage of trust anchors.  ...  Unfortunately, widely used mechanisms, management models and usage practices related to trust anchors undermine security and impede flexibility.  ...  In some cases, a collection of trust anchors may be represented using a "certificates only" Cryptographic Message Syntax (CMS) SignedData message.  ...

Practical and Secure E-Mail System (PractiSES) [chapter]

Albert Levi, Mahmut Özcan
2004 Lecture Notes in Computer Science  
Since on-demand fetching of public keys is aimed in PractiSES, use of certificates is limited for inter-domain communications only; no certificates are used within a domain.  ...  PractiSES clients manage their public keys and obtain public keys of other users by using unique, secure and user-transparent protocols.  ...  PractiSES takes advantage over S/MIME applications by escaping use of certificates for masses and over PGP by less complicated trust mechanism based on a trusted third party.  ...
