Design, modeling, and simulation of secure X.509 certificate revocation
… In this dissertation, the standard for X.509 revocation is systematically reviewed and critically evaluated to identify its limitations and assess their impact on internet security. Because of fragmented revocation information and limited scalability, even the latest version of the X.509 …

A Security Model for Mobile Agents using X.509 Proxy Certificates
… for Computational Grids, and specifically, on X.509 Proxy Certificates. Proxy Certificates serve as credentials for Grid applications, and their primary purpose is temporary delegation of authority. Exploiting the similarity between Grid applications and mobile agent applications, this thesis …

Implementing EFECT
… of the optimized EFECT and a comparable X.509 [X509] system. This comparison serves as proof that EFECT does indeed outperform the X.509 scheme in some common scenarios.

Architecture for Issuing DoD Mobile Derived Credentials
… Infrastructure implemented through the use of X.509 certificates and private keys issued on smartcards called Common Access Cards (CAC). However, use of CAC credentials on smartphones is difficult due to the lack of effective smartcard reader integration with mobile devices. The creation of a …

Federated identity management systems for cyberinfrastructure: SAML vs. PKIX
… (SAML) and Public Key Infrastructure with X.509 Certificates (PKIX). These systems have found favor in different scientific computing communities but it is unclear what the difference in preference is based upon. In this study we discuss the security, usability, privacy and trust model …

Improving the security services of the message handling systems in X.400.
… X.400 message-token which conforms to the X.509 one-way authentication protocol cannot protect X.400 messages from the attack of impersonation. An exisiting solution in terms of the one-way authentication protocol still cannot solve this problem when it is applied as a message-token in MHS. …

Scalable authentication for consumer-side smart grid Internet of Things
… much easier and ask if existing solutions like X.509 certificates scale to large device populations. We also look at what information needs to be exchanged between devices in order to provide strong and secure authentication. The evaluation shows that existing schemes need to be given a second …

Enabling easy access to Grid storage services and digital repositories
… for the authentication and the management of X.509 certificates, a mandatory requirement to get access to distributed storage services. We propose a novel data management architecture, exploiting SAML based authentication, credential delegation, WebDAV and HTTP-standard redirections. This allows …

Implementación de un Sistema SSO centralizado
… el tráfico para exigir certificado digital X.509 en el acceso a recursos críticos. Se concluye que la arquitectura diseñada mitiga eficazmente el riesgo de la suplementación de identidad, centraliza la trazabilidad y elimina la fatiga de contraseñas. Además, el aislamiento del tráfico en la …

Automated security analysis of payment protocols
… digests, message authentication codes and X.509 certificates are modeled. Using TGPay, PTGPA performs analyses of payment protocols under two scenarios in full automation. An Alpha-Scenario is one in which a candidate protocol runs in a perfect environment without attacks from any intruders. …

Digital Receipts: A System to Detect the Compromise of Digital Certificates
The ease of copying digital materials creates difficulty in detecting the theft of digital certificates. Uneducated users frequently fail to protect their digital certificate keys by not encrypting them, storing them in insecure places, and using them unwisely. In addition, there is no way to prove …
