Overview of the secure secret provisioning (SSP) on STM32MP1 Series Application note
■The outsourcing of product manufacturing enables the original equipment manufacturers (OEMs) to reduce their direct costs and concentrate on high added-value activities such as research and development, sales and marketing.
■However, the contract manufacturing puts the OEM's proprietary assets at risk, and since the contract manufacturer (CM) manipulates the OEM's intellectual property (IP), it might be disclosed to other customers, or appropriated.
■To meet the new market security requests and protect customers against any leakage of their IPs, STMicroelectronics introduces a security feature, the secure secret provisioning (SSP), allowing the programming of OEM secrets into STM32MP1 one time programming (OTP) area in a secure way (with confidentiality, authentication and integrity checks).
■The STM32MP1 Series supports protection mechanisms allowing the protection of critical operations (such as cryptography algorithms) and critical data (such as secret keys) against unexpected access.
This application note gives an overview of the STM32MP1 Series SSP solution with its associated tools ecosystem and explains how to use it to protect OEM secrets during the CM product manufacturing stage.
