Securing Internet Routing: Measuring and Improving the Resource Public Key Infrastructure
… (ASes) but lacks built-in security. The Resource Public Key Infrastructure (RPKI) enhances BGP security by verifying route authenticity through Route Origin Validation (ROV). However, its effectiveness remains limited by partial adoption, misconfigurations, and collateral routing effects. This …

Public Key Infrastructure (PKI) And Virtual Private Network (VPN) Compared Using An Utility Function And The Analytic Hierarchy Process (AHP)
This paper compares two technologies, Public Key Infrastructure (PKI) and Virtual Private Network (VPN). PKI and VPN are two approaches currently in use to resolve the problem of securing data in computer networks. Making this comparison difficult is the lack of available data. Additionally, an …

Wireless Authentication Using Remote Passwords
… rely on globally shared secrets or heavyweight public-key infrastructure. Wireless Authentication using Remote Passwords (WARP) mitigates authentication woes by providing usable mechanisms for both administrators and end-users. Administrators grant access by simply adding users' personal …

Federated identity management systems for cyberinfrastructure: SAML vs. PKIX
In scientific infrastructures researchers accessing computing and other resources (e.g., instruments, data) across institutional boundaries rely on federated identity management systems. Multiple competing technologies are in use for this purpose, including Security Assertion Markup Language (SAML) …

Implementation of Secure DNP3 Architecture of SCADA System for Smart Grids
… DNP3 SAv5 and design a secure architecture with Public Key Infrastructure (PKI) on Asymmetric key encryption using a Certificate Authority (CA). The testbed provides a design architecture between customer and distribution substation and illustrates the verification of the public certificate. We …

Enabling easy access to Grid storage services and digital repositories
Currently, storage services provided by Grid infrastructures have been mostly used by IT-experts scientists, managers, and researchers due to the their underlying complexities such as protocols, access mechanisms, and user unfriendly interfaces, often based on command line tools. In particular, one …

Tracking certificate misissuance in the wild
… are responsible for delegating trust in the TLS Public Key Infrastructure (PKI). Unfortunately, there is a long history of CAs abusing this responsibility, either due to negligence or in some cases, falling victim to attacks. As a result, the PKI community has established standards that define …

LOKI : a lease-oriented key infrastructure with instant updates and seizure-resistance
… Authentication is typically achieved using a Public Key Infrastructure (PKI) that enables users to verify a counterparty's public key binding. Unfortunately, the structure of many existing PKIs present vulnerabilities and usability issues that stem from a lack of consistency, inefficient …

Architecture for Issuing DoD Mobile Derived Credentials
… within the Department of Defense relies on Public Key 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 …

An authentication framework for securing guiset infrastructure
… grid resources exploited by end users is the public key infrastructure. It proves the identities of grid users through the use of certificates. GSI is one of the implementations of the PKI technology and delivers essential requirements in a security infrastructure and those include delegation …

Concretely-Efficient Multi-Key Homomorphic Secret Sharing and Applications
… without the use of fully homomorphic encryption. Public-key HSS is a well-known variant that supports inputs from multiple parties, but all parties must agree on a joint public key before any party can encode their inputs, requiring extra rounds of communication in applications. Recently, Couteau …

Collaborative Caching for efficient and Robust Certificate Authority Services in Mobile Ad-Hoc Networks
… many security frameworks did not consider it. Public-Key Infrastructure (PKI) is no exception, and its deployment in MANET needs major design and implementation modifications that can fit constraints unique to this environment. Our focus in this dissertation is to adapt and increase the …

Randomized algorithms for reliable broadcast
… to less a half fraction of faults, if there is a public-key infrastructure setup available that allows the players to compute (public-key) digital signatures. * Our protocols work even if the source of randomness is a "somewhat random" source (also called a Santha-Vazirani source). The price we …

SECURE AND EFFICIENT INFORMATION MANAGEMENT IN DELAY(DISRUPTION) TOLERANT NETWORK
… purposes. However, due to the damaged network infrastructure in the emergency, nodes need to relay messages using the store and forward paradigm, also called Delay-tolerant Networks (DTNs). In DTN, the limited bandwidth, energy, and contacts among the nodes, and their interdependency impose …

Scalable authentication for consumer-side smart grid Internet of Things
… between these constrained devices and critical infrastructure like the smart grid. In this thesis we explore the scalability of smart grid consumer-side IoT. We look at how the extremely connected nature of IoT makes vulnerability blooms much easier and ask if existing solutions like X.509 …

Design and Implementation of a Secure Communication Architecture
… using a certificate authority (CA)-based public key infrastructure (PKI). However, the security protocols and the CA-based PKI are not always able to address the challenges associated with these communications. The significant growth in online activities in our everyday life over time …

Design, modeling, and simulation of secure X.509 certificate revocation
… SSL certificates in 2022. The state-of-the-art Public Key Infrastructure (PKI), encompassing protocols, computational resources, and digital certificates, has evolved for 24 years to become the de-facto choice for encrypted communication over the Internet even on newer platforms such as mobile …

An investigation to cybersecurity countermeasures for global internet infrastructure.
… due to S-BGP encrypting the data by using public key infrastructure, while BGPsec utilises IPsec security suit to encapsulate the exchanged BGP packets. Therefore, neither of the two methods (S-BGP and BGPsec) are considered as Intrusion Detection Systems (IDS). Furthermore, S-BGP and …
