We present an implementation of an EC cryptographic library targeting three main objectives: portability, modularity, and ease of use. Our goal is to provide a fully-equipped library of portable source code with clearly separated modules that allows for easy development of EC cryptographic protocols, and which can be readily tailored to suit different(More)
We present a variant of the complex multiplication method that generates elliptic curves of cryptographically strong order. Our variant is based on the computation of Weber polynomials that require significantly less time and space resources than their Hilbert counterparts. We investigate the time efficiency and precision requirements for generating(More)
Wireless sensor networks are expected to make a significant contribution in the healthcare sector by enabling continuous patient monitoring. Since medical services and the associated to them information are considered particularly sensitive, the employment of wireless sensors in medical environments poses many security issues and challenges. However,(More)
We consider a variant of the Complex Multiplication (CM) method for constructing elliptic curves (ECs) of prime order with additional security properties. Our variant uses Weber polynomials whose discriminant D is congruent to 3 (mod 8), and is based on a new transformation for converting roots of Weber polynomials to their Hilbert counterparts. We also(More)
Wireless sensor networks are comprised of a vast number of ultra-small autonomous computing, communication and sensing devices, with restricted energy and computing capabilities , that cooperate to accomplish a large sensing task. Such networks can be very useful in practice, e.g. in the local monitoring of ambient conditions and reporting them to a control(More)
