Digital signatures have been proposed by several researchers as a way of preventing execution of malicious code. In this paper we propose a general architecture for performing the...
The modulation transfer function (MTF) has long been used as a diagnostic tool for analog image capture, by tracking frequency response caused by aperture, field position, or defo...
- In recent years, many quantum cryptographic schemes have been proposed. However, it seems that there are many technical difficulties to realize them (except Quantum Key Distribut...

Single-bit second-order delta-sigma modulators are commonly used in high-resolution ADCs. Testing this type of modulator requires a high-resolution test stimulus, which is diffic...
The industry is currently starting to use MPEG-4 compressed digital video for surveillance applications. The transition from analog to digital video raises difficulties for using ...
