However, as a first step before using the STM32Trust framework, it is necessary to perform an in-depth analysis of your security model, based on the outcome of your threat analysis. Certified Common Criteria EAL5+, the STSAFE portfolio offers multiple devices for secure connectivity which are essential for cloud communications, secure storage and authentication, and system integrity.Дeveloped in close collaboration with partners and customers, STM32Trust builds on several asset-protection use cases and the security features they require, as shown in the examples below. To enhance the Security Assurance Level, STM32Trust also supports secure elements from the STSAFE product family. This assurance level allows designers to build their applications using a solid security framework and to meet the requirements of their pre-defined security assurance level, such as PCI, UL-2900, IEC 62443, ETSI EN 303 645, FIPS-140-2 and many others. To ensure best-in-class security, ST provides MCUs and MPUs with their associated security functions based on PSA and SESIP certifications. With a set of 12 security functions offering hardware, software, and design services from ST and third parties, STM32Trust complies with the requirements of the major IoT certification schemes. This solution offers developers a complete toolset to protect their designвЂ™s valuable assets, such as software IP and data, and to ensure secure connectivity and system integrity. STM32Trust is a security framework combining our knowledge, ecosystem, and security services. STM32Trust offers a robust multi-level strategy to enhance security in new product designs based on our STM32 microcontrollers and microprocessors augmented with STSAFE secure elements.
