   Abstract We present the results of a new reverberation mapping campaign for the broad-line active galactic nucleus (AGN) in the edge-on spiral IC 4329A. Monitoring of the optical continuum withV-band photometry and broad emission-line flux variability with moderate-resolution spectroscopy allowed emission-line light curves to be measured for Hβ, Hγ, and Heiiλ4686. We find a time delay of ${16.3}_{-2.3}^{+2.6}$days for Hβ, a similar time delay of ${16.0}_{-2.6}^{+4.8}$days for Hγ, and an unresolved time delay of $-{0.6}_{-3.9}^{+3.9}$days for Heii. The time delay for Hβis consistent with the predicted value from the relationship between AGN luminosity and broad-line region radius, after correction for the ∼2.4 mag of intrinsic extinction at 5100 Å. Combining the measured time delay for Hβwith the broad emission-line width and an adopted value of 〈f〉 = 4.8, we find a central supermassive black hole mass of $M_{\mathrm{BH}}={6.8}_{-1.1}^{+1.2}\times {10}^7$M_⊙. Velocity-resolved time delays were measured across the broad Hβemission-line profile and may be consistent with an “M”-like shape. Modeling of the full reverberation response of Hβwas able to provide only modest constraints on some parameters, but does exhibit agreement with the black hole mass and average time delay. The models also suggest that the AGN structure is misaligned by a large amount from the edge-on galaxy disk. This is consistent with expectations from the unified model of AGNs, in which broad emission lines are expected to be visible only for AGNs that are viewed at relatively face-on inclinations.

3. Global Attack and Remedy on IC-Specific Logic Encryption

   In recent years, semiconductor industry has out-sourced the manufacturing to low-cost but not necessarily trusted foundries. This fabless business model encounters new security challenges, including piracy and overproduction. A well-studied solution to prevent unauthorized products from functioning is logic encryption, where a chip is encrypted using a key only known to the designer. However, the majority of the logic encryption solutions are vulnerable due to key uniformity and probing attacks. In this paper, we first present GSAT, a Global attack on existing IC-specific logic encryption schemes using the SAT model, that effectively deciphers the hidden global key pluggable to all the encrypted ICs. Next, we propose a highly secure and low-cost remedy called SPLEnD: Strong PUF -based Logic Encryption Design. Traditional I C-specific encryption schemes are vulnerable to GSAT attack, while SPLEnD not only effectively resists GSAT, but also balances security and efficiency.
