Lightweight Key Establishment for WSNs
2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM), 2019In this paper we present two Lightweight Key Establishment (LKE) solutions for Wireless Sensor Networks (WSN). We explore area and energy oriented design goals. The protocol used in the LKE systems, relies on novel lightweight elliptic curve scalar multiplication architectures and on a lightweight block cipher.

Key Establishment is one of the most intriguing, fascinating and deeply studied problems in Cryptography. In this paper we propose a brief excursus among ideas and techniques that during the last years have been applied in a variety of settings, in order to design suitable and often mathematically delightful protocols to solve this issue.

Secure group key establishment revisited
International Journal of Information Security, 2007We examine the popular proof models for group key establishment of Bresson et al. (LNCS 2248: 290–309, 2001; Proceedings of the 8th ACM conference on computer and communications security (CCS-8), 2001) and point out missing security properties addressing malicious protocol participants.

An on-demand key establishment protocol for MANETs
International Journal of Wireless and Mobile Computing, 2006Securing ad hoc networks is a challenging task due to their specific characteristics. One of the major challenges is that ad hoc networks typically lack a fixed infrastructure both inform of physical nodes such as routers, servers, and stable communication links and in the form of an organizational or administrative infrastructure. New nodes can hence,

As electronic communications and information services become more sophisticated, many applications involving multiple entities become necessary. Since these applications will generally require secure communications it is necessary to design protocols that establish keys for groups of principals.

So far we have tacitly assumed that all cryptographic algorithms can be readily used assuming that a suitable collection of secret and public keys is already distributed and known to the parties. For instance, secrecy systems based on secret key encryption require the same key to be shared by both the sender and receiver.

Deriving Secrecy in Key Establishment Protocols
2006Secrecy and authenticity properties of protocols are mutually dependent: every authentication is based on some secrets, and every secret must be authenticated. This interdependency is a significant source of complexity in reasoning about security. We describe a method to simplify it, by encapsulating the authenticity assumptions needed in the proofs of

Reducing the Cost of Session Key Establishment
2009 International Conference on Availability, Reliability and Security, 2009Scenarios such as online banking, mobile payment systems, stock trading, selling merchandise, and a host of other applications that need a high level of security have moved from the research domain to real world. Moreover, the nature of clients has been changing from traditional desktops to mobile and handheld devices.
