IC Decryption Technologies Introduction

IC decryption is mainly applied to PCBA clone; it trends to program research in the future. IC decryption is furthermore known as MCU fracture and chip decryption, a process that harm use special products to have key information on the computer chip by various technical methods. These approaches are called IC decryption technologies. Right here we introduce many IC decryption systems.

As Clone PCB of fact, nick crack is the kind of accurate and complicated high end science and technological innovation. Software attack, electric detection attack, mistake generated technology and even probe technique are common IC decryption technologies. Now pcb reverse engineering of us make a thorough introduction to all of them.

1 . Software strike

This method means to be able to find out MCU's design defect by way of softwares and read out internal OTP/flash ROM or EEPROM code. This is usually not a great IC decryption technology mainly because it takes a lot of research time in addition to each chip using the same sequence is different.

2 . not Electronic detection harm

This method generally monitors simulation functions of processor's all power supplies attaching with interfaces along with high time resolution; furthermore, it conducts attack by monitoring its electromagnetic radiation characteristics. MCU is definitely an active electronic part, when it functions different instructions, typically the corresponding power usage also changes accordingly, so the major information can always be acquired by analyzing and detecting these kinds of changes with exclusive electronic measuring instruments and mathematical record methods.

3. Mistake generated technological innovation

This specific IC decryption technologies uses abnormal working conditions to create processor chip error, and then offers additional usage of attain information. One of the most widely used fault developed attack methods contain voltage surge, clock shock; low voltage and high voltage attack can turn out to be used to stop protection circuit operating or force cpu to execute defective operation. Clock transient jump can reset to zero the protection outlet but not damage safeguarded information; power present and clock transient jump can impact individual instruction decoding and execution in a few cpus.

4. Probe strategy

Probe technique in addition to FIB technique happen to be popular IC decryption, but their value is high. Probe technique directly exposes chip's interconnect and next observes, controls and interferes MCU in order to achieve attack. IC crack includes unpleasant attack and non-invasive attack.
