What type of keystore implementation would prevent complicated forensic data extractions and analysis of lost or stolen devices for example, leaking information via power, timing, electromagnetic radiation, and thermal radiation examination?

StrongBox is a hardware-backed keystore implementation that provides the highest level of security for cryptographic keys. It is designed to resist advanced physical attacks, including side-channel analysis like power, timing, electromagnetic, and thermal radiation examinations. This makes it extremely difficult for attackers to extract sensitive information from a lost or stolen device, even with sophisticated forensic tools. StrongBox achieves this by isolating key material within a secure hardware module, making it inaccessible to the main operating system or other software. The other options listed are not recognized or standard Android keystore implementations.
