Microchip’s hardware-encrypted micro for IoT

时间:2016-05-09 09:41来源:Electronics Weekly.com 作者:MEMS 点击:
Microchip has launched a hardware crypto-enabled 32-bit microcontroller which can add security to IoT devices, offering encryption and authentication.

The chip allows for pre-boot authentication of the system firmware in order to ensure that the firmware is untouched and uncorrupted, thereby preventing security attacks such as man-in-the-middle, denial-of-service and back-door vulnerabilities.

It can also be used to authenticate firmware updates, protecting the system from malware or memory corruption.

The Device offers private key and customer programming flexibility with a full-featured micro controller in a single-package solution in order to minimise customer risk.

The device provides savings in terms of power drain and also improved execution of application performance. In addition, since the CEC1302 is a full 32-bit microcontroller with an ARM Cortex-M4 core, adding security functionality only results in a small additional cost.

The CEC1302 can be used as a standalone security coprocessor or can replace an existing microcontroller. The hardware-enabled public key engine of the device is also 20 to 50 times faster than firmware-enabled algorithms, and the hardware-enabled hashing is 100 times faster.

In order to quickly develop applications based on the CEC1302, MikroElektronika’s CEC1302 Clicker (MIKROE-1970) and CEC1302 Clicker 2 (MIKROE-1969) boards can be used with MikroElektronika’s complete development toolchain for Microchip CEC1302 ARM Cortex-M4 MCUs which includes compilers, development boards, programmers/debuggers or with standard third-party ARM® MCU toolchains.
