My customer have a question that according to CC13x2, CC26x2 SimpleLink Wireless MCU Technical Reference Manual (Rev. E) (ti.com), each time the key is read from outside the security module (NVS), and loaded into the key-store RAM area. So the keys are stored outside the security module after power is off. Is that our key storage scheme?
In addition, if we want the keys not stored in a flash that contains normal programs/data, to prevent the attackers from obtaining the keys easily, how can you prevent unauthorized access (for example disassembled separately)
