X-ray pulsar-based navigation (XNAV) using one X-ray detector is investigated as an augmentation to the capability of an ultraviolet (UV) sensor-based satellite autonomous navigation system. The satellite state dynamics are analyzed to establish the dynamical equations of the satellite autonomous navigation system. A time transformation equation that(More)
Wireless Implantable Medical Devices (IMDs), including pacemakers and cardiac defibrillators, often have built-in wireless modules in order to facilitate non-invasive programming and data read-out; however, most IMDs lack a security mechanism. The unique challenge is that IMDs should be able to be accessed by doctors at any legitimate hospital for emergency(More)
We present an electrocardiogram (ECG)-based data encryption (EDE) scheme for implantable medical devices (IMDs). IMDs, including pacemakers and cardiac defibrillators, perform therapeutic or even life-saving functions and store sensitive data; therefore, it is important to prevent adversaries from having access to them. The EDE is designedwith the ability(More)
Generating random binary sequences (BSes) is a fundamental requirement in cryptography. A BS is a sequence of <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula> bits, and each bit has a value of 0 or 1. For securing sensors within wireless body area networks (WBANs), electrocardiogram (ECG)-based BS generation methods have been(More)
As defined by IEEE 802.15.6 standard, channel sharing is a potential method to coordinate inter-network interference among Medical Body Area Networks (MBANs) that are close to one another. However, channel sharing opens up new vulnerabilities as selfish MBANs may manipulate their online channel requests to gain unfair advantage over others. In this paper,(More)
Random Binary Sequences (BSs) play an important role in cryptographic algorithms. In order to secure Wireless Body Area Networks (WBANs), electrocardiogram (ECG) signal-based BS generation algorithms were studied in previous papers. These algorithms process Inter-pulse Intervals (IPIs) from the ECG signal, which normally needs about 20 to 30 seconds to(More)
