An optimized certificate-based protocol for mobile network with authentication and security
has been proposed by Yi et al. This protocol allows efficient computation and less storage …

Mutual authentication and session key exchange protocols based on certificates for the
wireless mobile communication/computing system are proposed. First, two improved …

In this work, we analyze and extend a recently proposed design of digital certificates called
TESLA certificates. Certificates are a necessary tool in today's secure networks to certify the …

A recent trend of wireless technology is to set up the wireless connections among close-by
mobile nodes. This class of network is called as Mobile Ad Hoc Network (MANET). In …

With rapid growth of mobile wireless networks, handheld devices are popularly used by
people and many mobile applications have been rapidly developed. Mutual authentication …

Recently, Mokhtarnameh, Ho, Muthuvelu proposed a certificateless key agreement protocol.
In this paper, we show that their protocol is unsecured against a man-in-the-middle attack. In …

We have developed a public key certificate validation system considering the restrictions
peculiar to the mobile environment, such as processing the speed and memory capacity of a …

Due to the resource constrained property of mobile ad hoc networks (MANETs), making their
application more lightweight is one of the challenging issues. In this area, there exists a …

ABSTRACT PKI or public key infrastructure is used many security solutions that are
designed for mobile ad hoc networks. These networks have special features that distinguish …

The characteristics of mobile ad hoc networks (MANETs) such as dynamic changing
topology, lack of centralized management, and the vulnerability of links, have made …
