Nuovo DRM Paradiso: Towards a Verified Fair DRM Scheme [PDF]

open access: yes, 2007
We formally specify the recent DRM scheme of Nair et al. in the µ crl process algebraic language. The security requirements of the scheme are formalized and using them as the basis, the scheme is verified. The verification shows the presence of security weaknesses in the original protocols, which are then addressed in our proposed extension to the ...

Remote Desaturation of Unprotected Amines and C─H Amination of Alkanes by Polarity‐Matched N‐Radical Cations

open access: yesAngewandte Chemie, EarlyView.
Highly electrophilic N‐radical cations enable efficient and selective H‐atom transfer (HAT) of unprotected amines. In this exceedingly practical strategy, simple CuCl catalyzes an interrupted Hofmann–Löffler–Freytag (HLF) reaction to afford δ desaturated amines, aza‐heterocycles, and C─H aminated alkanes without protecting groups.

Synergy Between Photon‐to‐Phonon Pathway and Active Lattice Oxygen Enables Efficient and Stable Syngas Synthesis

open access: yesAngewandte Chemie, EarlyView.
This work reports the design of a multifunctional MnOx support coupled with classic Rh catalytic centers for light‐driven dry reforming of methane. Benefiting from efficient photon‐to‐phonon conversion pathway and a dynamic OL‐OV cycle, the catalyst achieves high syngas production rates and light‐to‐chemical energy efficiency without external heating ...

Open DRM and the Future of Media [PDF]

open access: yesIEEE Multimedia, 2008
Consumers want to use their digital content in the same way they have always used analog content. Consumer associations and governments are starting to request and even impose interoperability between DRM vendors' products. Therefore, interoperability has become a hot topic among content creators and distributors.
