> Ou un proc capable d'executer du crypté ?
Une intégration du chiffrage assez profondément dans la plate-forme est malheureusement loin d'être impossible... AD intègre ça sur sa nouvelle famille de Blackfin BF-54x, voir http://www.analog.com/en/content/0,2886,763%255F207%255F113650,00.html
Extrait:

Lockbox Security Features Protect Intellectual Property The Blackfin ADSP-BF54X family also incorporates new Lockbox™ Secure Technology that allows developers to ensure code and data integrity through authentication, and to safeguard confidentiality by means of encrypting any or all of the system. Not only does this provide a means for developers to protect the intellectual property of their own products, but it also offers a platform for the digital rights management (DRM) content protection that is required for devices such as media players. In addition, the programmable aspect of the Lockbox software-based system gives system designers the opportunity to choose any encryption algorithm they prefer.

Vive les DRM !
