TamperErkennung

TamperErkennung, also known as tamper detection or tamper resistance, refers to the mechanisms and techniques employed to identify or prevent unauthorized physical modification of a system or device. The primary goal is to ensure the integrity and security of the protected item by alerting users or disabling the system if tampering is detected.

These methods can range from simple physical indicators to sophisticated electronic systems. Physical indicators might include security seals, holographic labels, or frangible materials that visibly break or change when an attempt is made to open or alter the device. Tamper-evident seals are commonly used on packaging and sensitive equipment.

More advanced tamper detection involves electronic sensors. These can monitor for changes in voltage, current, or the presence of specific frequencies. For instance, in hardware security modules (HSMs) or secure microcontrollers, internal sensors can detect attempts to drill into the chip, apply excessive voltage, or expose it to light. Upon detection, these systems may erase sensitive cryptographic keys or enter a secure, non-functional state to prevent data compromise.

Tamper detection is crucial in various sectors, including cryptography, secure storage, industrial control systems, and payment terminals. It serves as a vital layer of defense against physical attacks, ensuring that the intended security features and data remain protected from malicious interference. The effectiveness of tamperErkennung is often a key consideration in the overall security design of a system.
