- EAP-TLS Smartcards, From Dream to Reality
- This paper presents the first implementation of the EAPTLS (Extensible Authentication Protocol-Transport Layer Security) protocol in smartcards. Tests, performed on two java devices, are discussed and analysed. Results show that TLS processing is slow, because smartcards are not yet optimized for that purpose; however the paper clearly demonstrates that TLS...

- Integrating a Signature Module in SSL/TLS
- SSL/TLS is currently the most deployed security protocol on the Internet. SSL/TLS provides end-to-end secure communications between two entities with authentication and data protection. However, what is missing from the protocol is a way to provide the non-repudiation service. This paper describes a generic implementation of the non-repudiation service as...

- OpenLDAP SSL/TLS How-To
- OpenLDAP has the ability to enable SSLv3 capabilities. Similar to SSL is Transport Layer Security (TLSv1). While SSL operates on a secure connection (ldaps://:636) and is a Netscape-defined protocol, TLS offers the same encryption on regular LDAP connections (ldap://:389) and is an industry standard (RFC 2830). Both types of secure...
