ATECC608C数据手册Microchip中文资料规格书

描述 Description

The Microchip ATECC608C integrates ECDH (Elliptic Curve Diffie Hellman) security protocol an ultra-secure method to provide key agreement for encryption/decryption, along with ECDSA (Elliptic Curve Digital Signature Algorithm) sign-verify authentication for the Internet of Things (IoT) market including home automation, industrial networking, medical, as well as accessories and consumables authentication and more. In addition, the ATECC608C offer an integrated AES hardware accelerator strengthening hardware based security and enable secure boot capabilities for very small microcontrollers. The ATECC608C is a secure element from the Microchip CryptoAuthenticationTM portfolio with advanced Elliptic Curve Cryptography (ECC) capabilities. With ECDH and ECDSA being built right in, this device is ideal for the rapidly growing IoT market by easily supplying the full range of security such as confidentiality, data integrity, and authentication to systems with MCU or MPUs running encryption/decryption algorithms. Similar to all Microchip CryptoAuthentication products, the new ATECC608C employs ultra-secure hardware-based cryptographic key storage and cryptographic countermeasures which eliminate potential backdoors linked to software weaknesses.The device is agnostic of any microprocessor (MPU) or microcontroller (MCU) and compatible with Microchip AVR/ARM MCUs or MPUs. As with all CryptoAuthentication devices, the ATECCC608C delivers extremely low-power consumption, requires only a single GPIO over a wide voltage range, and has a tiny form factor making it ideal for a variety of applications that require longer battery life and flexible form factors.To help accelerating your development, take a look at the Trust Platform for the ATECC608C and consider :- ATECC608C Trust&GO for TLS based network secure authentication. The device comes pre-provisioned secure element with a generic static certificate to reduce third party certificate authority costs. No configuration needed allowing you to focus solely on your application code. Compatible with AWS IoT Multi-account registration architecture. - ATECC608C TrustFLEX for TLS based network secure authentication in addition to many more use cases. The device comes pre-configured device with more use cases than just the device to cloud secure authentication Trust&GO offer. It offers pre-architected implementation for accessory authentication, firmware validation, secure boot assistance, key rotation and more. Compatible for AWS IoT, Microsoft Azure and in general any TLS networks with code examples for WolfSSL, mBedTLS, CycloneSSL. - ATECC608C TrustCUSTOM secure element is a fully customizable device in case your security architecture demands to go beyond the Trust&GO and TrustFLEX use cases. - For Linux systems, the Trust Platform ATECC608C variances leverage the PKCS#11 interface between the microprocessor and the secure element. Check our code example.
