Quickly Enable/Disable Radios
Posted: Sun Dec 30, 2018 9:48 pm
Is there an elegant way to quickly disable and enable radios (wifi and bluetooth) or just the analog amplifier? I am trying to implement some code to mitigate [screamingchannels][http://s3.eurecom.fr/docs/ccs18_camurati.pdf], which essentially just requires the radio amplifier(s) to be disabled during cryptographic operations. Essentially, turn off radios, perform operations (order of mS), then turn the radios back on like nothing ever happened.
On a related note, does the esp-idf team think that the flash encryption keys in the efuses can be leaked in this fashion?
