Referring to Introduction to differential power analysis (Paul Kocher, Joshua Jaffe, Benjamin Jun, Pankaj Rohatgi)

Because the amount of power used by a device is influenced by the data being processed, power consumption measurement… Continue reading How can differential power analysis (DPA) still work without "sufficient" measurement resolution?
Looking at a plain system (there are no security controls implemented yet), we need to think about its functions and derive appropriate assets which we’d like to protect in order to ensure the system continues to function as intended (also… Continue reading Are security controls themselves considered assets (e.g., cryptographic keys)
I think I quite well understand the theoretical benefit of adding the HMAC (authenticity/integrity on top of confidentiality), but I am looking at this from a key management point-of-view.
Premise: Since anyone could in theory encrypt pla… Continue reading Is HMAC really a benefit for AES-CBC?
