UVODABSTRACT This paper presents the extension of an existing software with PVR application. The application is developed and tested on the satellite STB device with Neotion NP6 SoC and the Linux OS. Implemented functions are time-shift, recording of current viewed service, recording via timer and trick modes.

This paper presents results regarding the progress achieved in the design of a customized encrypted multiplexer cell. The focus of our interest is the no short-circuit dynamic differential logic method that demonstrates high immunity of a standard logic cell to the side channel attacks (SCAs). Three innovative solutions are examined and the best one is proposed for the encrypted multiplexer cell. Designed cells are realized to the layout masks level targeting the 350[Formula: see text]nm CMOS process. The post-layout simulations showed high resistivity to the SCA for all designed cells. The resistance to the SCA of the proposed design was statistically verified at the transistor level. The verification is performed using the Monte Carlo (MC) simulation in which widths and lengths of the transistor channel were varied according to the Gaussian distribution. The designed encrypted cell will be the part of a more complex crypto system for power consumption metering which should increase overall system’s data security.

This paper deals with a top down design of an example multiplexer cell that exhibits high immunity to Side Channel Attack (SCA). Four different solutions of the encrypted multiplexer cell are revised, and the best design adopted. The post-layout simulations prove resistance of the multiplexer logic cell to the SCA. Since the physical layout structure and the functionality of this kind of design is based on symmetry, concerns were expressed as to what will be the effectiveness of the method under real production conditions. To get a proper answer to that, the adequacy of the chosen design for the multiplexer cell, which uses the "No Short-circuit Current Dynamic Differential Logic" (NSDDL) method, is confirmed by observing a Normalized Standard Deviation (NSD).
