With the rapid adoption of connected nodes and cloud-based infrastructures, the frequency of security threats is always increasing. Securing your embedded system is a necessity, but the solution you select will depend on the type of security you need, the cost of implementation, the level of risk tolerance and the ease of development. Our 32-bit microcontrollers (MCUs) offer some of the most comprehensive and scalable security options available in the market today. They are supported by a comprehensive ecosystem of hardware, software, tools and functions to make it easy to implement effective protection for your embedded application.
Security begins with hardware. Our 32-bit MCU security portfolio has integrated hardware-based security features. Hardware-based security is faster, has higher performance and is more secure than software-only solutions.
Save time by jump-starting your design process with MPLAB® Harmony, an award-winning embedded software framework for MIPS® and Arm® Cortex®-M based 32-bit MCUs. We also provide comprehensive cryptographic/security software support across development platforms.
Security measures can be further reinforced with third-party security software. We’ve worked with several third parties to provide easy-to-use security development options.
Symmetric Cryptography (Secret Key)
Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext.
Asymmetric Cryptography (Public Key)
Public-key cryptography, or asymmetric cryptography, is any cryptographic system that uses pairs of keys: public keys which may be disseminated widely, and private keys which are known only to the owner.
Integrity Check Monitors (Message Hash)
Message hashes transform variable-length data to a fixed-length piece of data. Integrity check monitors generate and validate message hash to preserve data integrity.
Hardware Root of Trust (Secure Boot)
A microcontroller that starts executing software from an internal, immutable memory (For example, ROM). The software stored in the microcontroller is considered inherently trusted (i.e., the root of trust) because it cannot be modified.
Secure Firmware Upgrade (Secure Bootloader)
A small section of code is added to the main application stored in the Flash of the MCU to provide the ability to download firmware upgrades. This code is called a bootloader, as its role is to load a new program at boot. Securing this code is essential to protect IP, assets and remote attacks and is the essential feature of secure bootloader.
True Random Number Generator
Hardware-based random generator offering a higher source of entropy for the generation of keys used in cryptographic applications.
Ability of a device to sense that an active attempt (mostly physical) to compromise the device integrity or the data associated with the device is active. The MCU can be programmed to take appropriate defensive actions upon detection.
Secure Key Storage
Protecting nonvolatile and volatile keys from remote and physical attacks.
Injection of secret identity data and cryptographic keys in a secure environment to maintain authenticity and integrity of an embedded application.
Hardware Isolation/IP Protection/TrustZone
Hardware-enforced isolation between the trusted and the untrusted resources of an application enabling IP protection.
