#141002 - what level of security? Responding to: ???'s previous message |
Task depends of required level of security.
Bit-by-bit is non informative, allmost useless, and one byte can be handled as one bit,encrypted packed of bytes - too. Aman Deep doesn't specify level of security. If data must be uchangeable , data must be physycally hidded/packed into MCU body. If device is someting like fiscal cash register - this is hardest variant to be hacked/replaced. |
