Our critical personal data is stored across a vast range of devices. Whether it be the biometric chip in your passport, the chip in your credit card, the GPS data in your phone or Apple Pay/Google Wallet on your phone or smartwatch, our personal data is stored across more devices than ever before.

Consequently, the ability to manipulate that information has never been easier. Cryptographic systems within the hardware of these devices seek to protect your critical data from manipulation, but what protects these systems from attacks?

Hackers are using ever more sophisticated tools and methods to read and manipulate our sensitive data stored within these systems.

Anti-tamper IP such as clock attack monitors and voltage glitch detectors play a vital role in detecting security attacks which involve the manipulation of clock signals or voltage levels to exploit vulnerabilities in electronic systems, which otherwise may result in the leaking of sensitive data.

Successful deployment of these technologies can stop attackers from gaining unauthorised access to these systems and avoid damage to critical infrastructure or the extraction of confidential information.
