Nowadays the wireless sensor networks (WSN) are increasingly being required for applications where the data reliability needs to be duly guaranteed. Due to this, many research works have been directed in this sense. However, WSN security is not an entirely solved issue. The aim on this chapter is to use Petri Nets (PN) to model and analyze the validity of(More)
In this paper, we propose a public key encryption scheme for wireless sensor networks. This scheme is based on elliptic curves defined over binary finite field and code low density parity check. A simplified model of the communication system is presented using Petri nets and also performance results for one peer to peer link are included.
The proliferation of mobile communication and computing technologies in supporting highly specialized tasks and services in health care has made it increasingly important to understand the factors essential to technology acceptance by health care sector. This paper presents an empirical evaluation of Mobile Acceptance in Health Service using a(More)
The objective of this paper is to develop and to validate a competition model which allows to determine when a cryptosystem type is the best-suiteddest to transmit in a communications channel, depending on the kind of technological used device (cellular phone, PDA, notebook, other ones). The results obtained for this dynamic analysis determine the kind of(More)
In this paper we propose the construction of an efficient cryptographic system, based on the combination of the ElGamal Elliptic Curve Algorithm and Low Density Parity Check (LDPC) codes for mobile communication. When using elliptic curves and codes for cryptography it is necessary to construct elliptic curves with a given or known number of points over a(More)
