Personal data are often collected and processed in a decentralized fashion, within different
contexts. For instance, with the emergence of distributed applications, several providers are …

HTTPS ensures that the Web has a base level of privacy and integrity. Security engineers,
researchers, and browser vendors have long worked to spread HTTPS to as much of the …

Certificate Transparency (CT) is an emerging system for enabling the rapid discovery of
malicious or misissued certificates. Initially standardized in 2013, CT is now finally beginning …

HTTPS aims at securing communication over the Web by providing a cryptographic
protection layer that ensures the confidentiality and integrity of communication and enables …

HTTPS is principally designed for secure end-to-end communication, which adds
confidentiality and integrity to sensitive data transmission. While several man-in-the-middle …

TLS and SSH are two well-known and thoroughly studied security protocols. In this thesis,
we focus on a specific class of vulnerabilities affecting both protocols implementations, state …

The main objective of this research is to explore the possibility of using blockchain and smart
contracts to provide a digital certificate for secure communication on the internet, which is …

The revolutionary Fifth Generation (5G) network technology has already been deployed in
many countries to provide end-to-end quality-of-service for a wide variety of services …

Transport Layer Security (TLS) is one of the most widely deployed cryptographic protocols
on the Internet that provides confidentiality, integrity, and a certain degree of authenticity of …

The aim of our research was to study security properties of real-world deployments of the
RSA cryptosystem. First we analyze RSA key generation methods in cryptographic libraries …
