CommScope, a provider of network connectivity solutions, has unveiled a bootloader signing solution designed specifically for Texas Instruments’ (TI) Arm-based AM6x processor family. This solution, built on CommScope’s PRiSM platform, aims to provide key protection using a FIPS-certified Hardware Security Module (HSM) and centralised lifecycle management, while supporting easy integration with TI's image build process.
The bootloader, responsible for verifying system integrity and preventing unauthorised software changes, seeks to ensure that firmware is authenticated before execution. This function involves protecting the private signing key used to authenticate firmware. A compromised key could undermine secure boot mechanisms. Recognising this, CommScope’s solution is designed to help manufacturers protect this key with hardware-backed security and regulated access. This development supports manufacturers in meeting cybersecurity mandates, such as the European Union’s Cyber Resilience Act (CRA) and other regional standards.
The CommScope PRiSM platform also seeks to provide full and robust key lifecycle protection. The signing keys, generated in a controlled multi-party process, are securely deployed in certified HSMs, without revealing themselves in software. Strict access control, policy enforcement, and seamless integration with TI’s SDK through cloud-accessible APIs further enhance key security, reduce unauthorised access risk, and ensure audit trails of signing operations.
With streamlined continual integration/continual delivery (CI/CD) and compliance to cybersecurity norms, this pathway facilitates secure boot adoption without imposing additional cryptographic infrastructure overhead on development teams.
Availability of the CommScope solution: It is scheduled for release in Q1 2026, with onboarding details accessible via TI’s partner page, where thorough resources and support are available. For those seeking broader understanding of CommScope's security solutions, visiting the CommScope PKI Center on their website will provide more information.
