Security issues with certificate authorities

2017 IEEE 8th Annual Ubiquitous Computing, Electronics and Mobile Communication Conference (UEMCON), 2017
The current state of the internet relies heavily on SSL/TLS and the certificate authority model. This model has systematic problems, both in its design as well as its implementation. There are problems with certificate revocation, certificate authority governance, breaches, poor security practices, single points of failure and with root stores.

Empowered Certification Authority in VANETs

2009 International Conference on Advanced Information Networking and Applications Workshops, 2009
The current research on privacy assurance in Vehicular Ad hoc Networks (VANETs) by pseudonym generation and network accountability through revocation has not achieved the desired results. Our research has identified the problems associated with the current techniques. We have revisited the pseudonym generation concept to address the privacy need of the

Evaluating certification authority security

1998 IEEE Aerospace Conference Proceedings (Cat. No.98TH8339), 2002
A growing number of applications in the Internet are making use of X.509 public key certificates. Examples include security protocols such as SSL (used in web browsers), IPsec (used in firewalls and desktop computers), S/MIME (a secure e-mail protocol), and SET (the electronic commerce credit card transaction protocol).

Certificate based authorization simulation system

25th Annual International Computer Software and Applications Conference. COMPSAC 2001, 2002
Using certificates for distributed authorizations in computer network systems has been discussed in the literature. However real implementations of the concept are rarely seen. In our certificate based authorization simulation system (CBASS) project, we prototyped a computer system including some of the emulated functions of an operating system such as

DNS Certification Authority Authorization (CAA) Resource Record

2019
The Certification Authority Authorization (CAA) DNS Resource Record allows a DNS domain name holder to specify one or more Certification Authorities (CAs) authorized to issue certificates for that domain. CAA Resource Records allow a public Certification Authority to implement additional controls to reduce the risk of unintended certificate mis-issue ...

A merging method of certification authorities without using cross-certifications

18th International Conference on Advanced Information Networking and Applications, 2004. AINA 2004., 2004
The public key infrastructure (PKI) technology is very important to support secure global electronic commerce and digital communications on networks. In electronic commerce, different PKIs need to be interoperated. Especially, they need to be merged for merger and acquisition of companies.

Certification Authority Liability Analysis

SSRN Electronic Journal, 1998
This paper surveys the liability issues raised by an entity’s entry into the certification authority business. Because the duties and potential liabilities imposed upon a CA by applicable law are unclear, this paper addresses the major sources of U.S.

Certification Authorities Under Attack: A Plea for Certificate Legitimation

IEEE Internet Computing, 2014
Several recent attacks against certification authorities (CAs) and fraudulently issued certificates have put the security and usefulness of the Internet public-key infrastructure (PKI) at stake. In this article, the author argues that such attacks are likely to occur repeatedly and that respective countermeasures must be designed, implemented, and put ...
