CryptoAuthentication™ Family

View All Parametrics

What Is the CryptoAuthentication Family?

Our CryptoAuthentication™ ICs deliver robust, hardware-based security that keeps secret cryptographic keys safe from unauthorized access. These compact, low-power devices integrate easily with any microcontroller (MCU) or microprocessor (MPU), making them excelent options for securing IoT nodes across applications like home automation, medical devices and wearables. They also ensure the authenticity of disposable and accessory devices, helping prevent counterfeiting and protecting your product integrity, users and revenue.

TA101 TrustMANAGER and TrustFLEX Early Adopter Program 

Get early access to TA101‑TFLX (TrustFLEX) and TA101‑TMNG (TrustMANAGER) beta silicon devices.

TA101‑TFLX is a robust secure key storage device paired with a set of predefined security protocols for teams who want to integrate TA101 into their own public key infrastructure (PKI) systems.

TA101‑TMNG includes the same key storage and protocol capabilities, but adds the keySTREAM cloud platform for remote configuration, PKI creation, key management, and firmware updates —removing the burden of building a managed IoT security infrastructure in‑house.

CryptoAuthLib Library

To streamline your development process with CryptoAuthentication devices like the ATECC608, ATSHA204A, ECC204, ECC206, SHA104, SHA105, SHA106, TA010 (automotive qualified) or ATSHA206A, we offer the CryptoAuthLib library. This software support library, written in C code, is essential for integrating cryptographic services into any application or device driver. It is compatible with a range of platforms, including Arm® Cortex®-M-based microcontrollers, PIC® microcontrollers and PCs that run Windows® or embedded Linux®.

CryptoAuthentication™ Secure Key Storage

Key Attributes

  • Easy to use: Basic Application Programming Interface (API) serves the needs of most applications
