CRP3 is set so I assume all is good and secure. However I saw a presentation at a security conference showing how to break NXP code read protection using a glitch attack. The presentation showed how quickly and easily CRP can be broken on the LPC1114. Is there anything that can be done to make this attack harder?</P></BODY></HTML> Wed, 29 Jan 2020 10:41:02 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Defense-against-glitch-attacks/m-p/1013613#M39679 philip_a_ocarro 2020-01-29T10:41:02Z Re: Defense against glitch attacks https://community.nxp.com/t5/LPC-Microcontrollers/Defense-against-glitch-attacks/m-p/1013614#M39680 <HTML><HEAD></HEAD><BODY><P>Hi philip</P><P>For secure applications, NXP recommends programming CRP level 3 as you have already configured.
