Arm TrustZone CryptoIsland family

The products within that CryptoIsland family provide local SoC entities and remote cloud entities with a comprehensive set of security services. They combine a compute engine, cryptographic capabilities, management of keys and other assets, with the intention of forming a smartcard level security on-die. 

The physical isolation (on-die) of the security subsystem allows it to be easily reused across designs, enabling a silicon vendor to reap the benefits of costly efforts, such as certification. This effort reuse is especially beneficial in domains like payment, identity and critical infrastructure.

Arm TrustZone CryptoCell-300 family

It provides the system with various cryptography related services and it also includes platform security services required to assure the integrity, authenticity and confidentiality of code and data belonging to different stakeholders (for example an OEM, a service provider or the user). 

The CryptoCell-300 family achieves all of these comprehensive services, while maintaining a small area and power consumption footprint (which is increasingly important for many IoT related deployments, including home automation, smart energy, automotive and more).
