Side-channel attacks (SCA) exploit unintended physical emissions—such as fluctuations in power consumption, electromagnetic radiation, or timing variations—to extract sensitive data, including cryptographic keys. By analyzing hardware behavior, SCA can bypass traditional security layers, posing a significant threat to systems that handle confidential operations.

Fault injection attacks (FIA) are a type of cyberattack that disrupts the normal operation of a system by deliberately introducing faults or errors. These attacks exploit hardware vulnerabilities to cause malfunctions, which can compromise sensitive data or bypass security mechanisms.

JmemTek's JShield technology effectively combats Side-Channel Attacks (SCA) and Fault Injection Attacks (FIA) through advanced hardware-centric safeguards. By utilizing a unique design in power and clock circuitry, JShield masks leakage patterns, rendering extracted signals unusable for attackers. Additionally, its masked JCrypt engines further dissociate cryptographic operations from observable physical outputs, effectively blocking electromagnetic and acoustic eavesdropping.
