Authentication Types
Symmetric Authentication
If your threat model steers you to implement symmetric authentication, our SHA105 host authentication IC will protect the key in the host system and SHA104 will protect the key in the accessory. To implement symmetric authentication in automotive applications such as card authentication or Electric Vehicle (EV) battery module authentication, our Trust Anchor TA100 CryptoAutomotive IC will provide secure host key storage in the main Battery Management System (BMS) and the TA010 will authenticate the battery modules.
Asymmetric Authentication
If you need to use asymmetric authentication for your security strategy, the ECC204 and ATECC608 CryptoAuthentication ICs will protect your public/private key pair, certificates and even symmetric keys. For automotive applications, the feature-rich TA100 and the more cost-effective TA010 can address your security requirements.
Other Capabilities
- Cloud Connectivity
- Identification
Adding Cloud Connectivity
When cloud connectivity and additional security use cases are required, consider using the ATECC608 for your host system or the TA100 for automotive applications. These secure authentication ICs will protect the private keys for Transport Layer Security (TLS) and Bluetooth® Low Energy (LE) sessions as well as the public keys for secure boot and secure firmware upgrades.
Are You Interested in Identification?
We offer a comprehensive portfolio of memory devices that can provide product identification without security capabilities.
Trust Platform Provisioning Service
Use the Trust Platform Provisioning Service with four unique tiers of customer support and certified secure factories to leverage our pre-configured and pre-provisioned secure ICs with the most common security use cases.
The Trust Platform Design Suite (TPDS) tool includes secure IC configurators and use cases supported by code examples and tutorials to accelerate your development.
Tools and Software
- Demo & Evaluation Boards
- Development Environment
The CryptoAuth Trust Platform provides a compact development solution for developing IoT solutions with the ATECC608B-TNGTLS and ATECC608B-TFLXTLS and ATECC608B-MAHDA devices or the ATECC608C equivalents.
The Microchip CryptoAuth Pro Trust Platform is an enhanced version of the CryptoAuth Trust Platform Board containing and has a Arm® Cortex®-M4F Microcontroller, four on-board CryptoAuthentication devices, two mikroBUS™ sockets, and an on-board 10/100 Mbit Ethernet phy. Programming can be done via the on-board PKoB4 debugger which is compatible with MPLAB®X IDE. The board has been developed to work with Microchip's Trust Platform Development Suite of tools.
The EV92R58A Development board is a mikroBUS accessory board for evaluating the ECC204. The board can readily be used with a Microchip DM320118 Trust platform host board or any MicroController board that supports a mikroBus Interface. It is recommended that this board be used with the Microchip CryptoAuthentication Library (CAL) .
The EV98D91A is a mikroBUSTM socket board for devices produced in a 2-Lead uVSFN contact package. The socket board supports theparasitically powered CryptoAuthenticationTM ECC204 and SHA106 devices. and also supports the AT21CS01. The CryptoAuthentication devices and socket kit can be used with the Microchip Trust Platform Development tools.
The EV27Y72A is a 3-Lead Contact Socket Board used to support applications using the 3-Lead Contact Package. in either a powered or parasitic power mode. The socket can be used with the following devices ATECC608B, ATSHA204A, ECC204, SHA104 and TA010.
The EV97M19A development board is a mikroBUSTM accessory board for evaluating the SHA104 and SHA105 CryptoAuthentication Devices. The board supports both the I2C and the SWI interface for the SHA104. The SHA105 host side device is only available in I2C mode.
The Trust Platform Design Suite (TPDS) is our onboarding tool for our security-related solutions. The full onboarding experience includes, but is not limited to:
- Training and education about security concepts
- Prototyping, including dummy key generation and code examples, available via our interactive application notes
- Access to our provisioning system through a secure sub-system configurator and secure exchange process
MPLAB X IDE is a highly configurable software platform that provides powerful, free tools for developing, debugging and qualifying embedded designs that use microcontrollers and digital signal controllers.
