Content based encryption sounds like a good idea to reduce power consumption. I would like to know more technical details of the idea such as how much power it saves.

Sounds like a good approach, but I wonder how much is saved (on average - I am sure it is media/image dependent) versus what additional power is used in the initial analysis? Looks like it works but getting major acceptance could prove a challenge.

Selective encryption reduces security by making it easier to find the data worth decoding. For example a check image would highlight a target of interest - even if part were encrypted. A clear text online order would provide valuable contextual information even if the credit card information were encrypted. With overall encryption, a lot of effort can be devoted to decoding what proves to be useless information.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
