ESS-04 : Ellipsys-SB is a bootstrap loader that can greatly enhance the security of embedded systems by cryptographically verifying (and optionally decrypting) that the code being loaded and executed is authentic and has not been tampered with. The solution includes developer tools to assist with deployment issues such as security updates, code signing and image building.

Ellipsys-SB is part of the Ellipsys Trust Framework which is Elliptic’s solution to help device manufactures and system providers protect their product from tampering, cloning, and other threats. Ellipsys-SB is a bootstrap loader that greatly enhances the security of embedded systems by cryptographically verifying (and optionally decrypting) that the code being loaded and executed is from a trusted source and has not been tampered with. The solution includes developer tools to assist with deployment issues such as security updates, code signing, and image building.

Secure environments like ARM TrustZone are a solid foundation for security solutions in Embedded Systems. Ellipsys-SB is an ideal fit for the ARM TrustZone architecture and it allows TrustZone enabled processors to boot into a secure state.

Once a feature of high security applications, the techniques are now being adopted in a broad range of products such as mobile phones, set-top boxes and networking systems such as base stations, routers and other infrastructure devices.

There are a number of variants for secure boot based on a blend of hardware cores and embedded software with options available for asymmetric and symmetric cryptographic approaches. Ellipsys-SB can work as a standalone solution or in tandem with other Ellipsys Trust Framework companions, such as Ellipsys-CA and Ellipsys-VSM.
