Traditional Certificate-based public key infrastructure (PKI) suffers from the problem of certificate overhead like its storage, verification, revocation etc. To overcome these problems, the idea of c...
In this work we apply the systematic approach of game-based security specifications and proofs by reductions, to the design and evaluation of public key infrastructure (PKI) schemes. The importance of...
In conventional PKI, CAs are assumed to be fully trusted. However, in practice, CAs' absolute responsibility for providing trustworthiness caused major security and privacy issues. To prevent such iss...

X509CLOUD - FRAMEWORK FOR A UBIQUITOUS PKI     PoW  OTP  XMPP       2017/6/9
The SSL protocol has been widely used for verifying digital identities and to secure Internet traffic since the early days of the web. Although X.509 certificates have been in existence for more than ...
It is well known that multivariate quadratic (MQ) digital signature schemes have small signatures but huge public keys. However, in some settings, such as public key infrastructure (PKI), both variabl...
A Decentralized PKI In A Mobile Ecosystem     PKI  GSM       2017/2/20
A public key infrastructure (PKI) supports the authentication and distribution of public encryption keys, enabling secure communication among other uses. However, PKIs rely heavily on a centralized tr...
Man-in-the-middle attacks in TLS due to compromised CAs have been mitigated by log-based PKI enhancements such as Certificate Transparency. However, these log-based schemes do not offer sufficient inc...
. SSL/TLS is the de facto protocol for providing secure communication over the Internet. It relies on the Web PKI model for authentication and secure key exchange. Despite its relatively successful ...
Message authentication and key exchange are two of the most basic tasks of cryptography. Solutions based on public-key infrastructure (PKI) are prevalent. Still, the state of the art in composable se...
Cryptographic accumulators are a tool for compact set representation and secure set membership proofs. When an element is added to a set by means of an accumulator, a membership witness is generated...
The security of most Internet applications relies on underlying public key infrastructures (PKIs) and thus on an ecosystem of certification authorities (CAs). The pool of PKIs responsible for the issu...
Trust Views for the Web PKI     Trust Views  the Web PKI       2014/3/5
The steadily growing number of certi cation authorities (CAs) assigned to the Web Public Key Infrastructure (Web PKI) and trusted by current browsers imposes severe security issues. Apart from being i...
We present the Plug-and-Play IP Security (PnP-IPsec) protocol. PnP-IPsec automatically establishes IPsec security associations between gateways, avoiding the need for manual administration and coordin...
Recent emergence of relatively inexpensive RFID tags capable of performing pub- lic key operations motivates new RFID applications, including electronic travel documents, identification cards and pa...
