System Security is one of the critical elements of modern era software & hardwares. There are many security solutions implemented in operating systems both at kernel level and user space level. But these security solutions are incomplete without the security mechanisms implemented at hardware initialization and boot time and lack of these could cause the whole system to be compromised. Given that fact the embedded devices are deployed for many mission critical operations there is huge risk of safety and security of users and devices.To make systems completely secure, security at firmware and bootloader level should be implemented. So, In this talk the authors will discuss various boot and firmware security mechanisms such as Secure Boot, OP-TEE, Secure Boot Chain, Arm Trusted Firmware (ATF). The authors will also discuss different security solutions based on aforementioned security mechanisms and how these mechanisms could be integrated with uboot for the different applications.
