Secure boot is a feature implemented in a computing device to ensure that only authorized code is run. This requires a way to verify the authenticity and integrity of the code. This means making sure that the code is what it claims to be and that it has not been tampered with. The goal is to gain trust in the integrity of the executed code.

Secure boot is beneficial for a wide range of devices, users and organizations, as it provides an additional layer of security. It establishes a secure and trusted foundation for the system’s boot process, mitigating various threats and ensuring that only authorized and digitally signed software components are allowed to run, thus enhancing the overall security level of the device.

Secure boot is used in government and public sector, critical infrastructure, financial institutions, healthcare, automotive, transportation and more. The implementation of secure boot is accompanied by various challenges that demand careful consideration.

• In terms of performance, the trade-off between security and efficiency becomes apparent, as the additional layer of verification can impact boot-up time and latency. Striking a balance is essential to maintain a responsive user experience.
• Resource utilization presents another challenge, requiring efficient and customized solutions in hardware and/or software depending on the target system.
• The security level of a secure boot system is a constant concern, with the ongoing challenge of preventing sophisticated hacking attempts. Additionally, safeguarding the trust anchor such as a public key used in the secure boot process is critical.
• Cost considerations encompass various aspects, including the allocation of resources for additional hardware and/or software within the device. Integrating secure boot into software development and deployment processes incur expenses too.
