DeepCover Embedded Security in IoT: Public-key Secured Data Paths

Dependencies:   MaximInterface

The MAXREFDES155# is an internet-of-things (IoT) embedded-security reference design, built to authenticate and control a sensing node using elliptic-curve-based public-key cryptography with control and notification from a web server.

The hardware includes an ARM® mbed™ shield and attached sensor endpoint. The shield contains a DS2476 DeepCover® ECDSA/SHA-2 coprocessor, Wifi communication, LCD push-button controls, and status LEDs. The sensor endpoint is attached to the shield using a 300mm cable and contains a DS28C36 DeepCover ECDSA/SHA-2 authenticator, IR-thermal sensor, and aiming laser for the IR sensor. The MAXREFDES155# is equipped with a standard Arduino® form-factor shield connector for immediate testing using an mbed board such as the MAX32600MBED#. The combination of these two devices represent an IoT device. Communication to the web server is accomplished with the shield Wifi circuitry. Communication from the shield to the attached sensor module is accomplished over I2C . The sensor module represents an IoT endpoint that generates small data with a requirement for message authenticity/integrity and secure on/off operational control.

The design is hierarchical with each mbed platform and shield communicating data from the sensor node to a web server that maintains a centralized log and dispatches notifications as necessary. The simplicity of this design enables rapid integration into any star-topology IoT network to provide security with the low overhead and cost provided by the ECDSA-P256 asymmetric-key and SHA-256 symmetric-key algorithms.

More information about the MAXREFDES155# is available on the Maxim Integrated website.

    \section intro_sec Introduction

 The SimpleLink CC31xx/CC2xx family allows to add Wi-Fi and networking capabilities
 to low-cost embedded products without having prior Wi-Fi, RF or networking expertise.
 The CC31xx/CC32xx is an ideal solution for microcontroller-based sensor and control
 applications such as home appliances, home automation and smart metering.
 The CC31xx/CC32xx has integrated a comprehensive TCP/IP network stack, Wi-Fi driver and
 security supplicant leading to easier portability to microcontrollers, to an
 ultra-low memory footprint, all without compromising the capabilities and robustness
 of the final application.



 \section modules_sec Module Names
 To make it simple, TI's SimpleLink CC31xx/CC32xx platform capabilities were divided into modules by topic (Silo). 
 These capabilities range from basic device management through wireless
 network configuration, standard BSD socket and much more.
 Listed below are the various modules in the SimpleLink CC31xx/CC32xx driver:
     -# \ref device - controls the behaviour of the CC31xx/CC32xx device (start/stop, events masking and obtaining specific device status)
     -# \ref wlan - controls the use of the WiFi WLAN module including:
       - Connection features, such as: profiles, policies, SmartConfig™
       - Advanced WLAN features, such as: scans, rx filters and rx statistics collection
     -# \ref socket - controls standard client/server sockets programming options and capabilities 
     -# \ref netapp - activates networking applications, such as: HTTP Server, DHCP Server, Ping, DNS and mDNS.
     -# \ref netcfg - controls the configuration of the device addresses (i.e. IP and MAC addresses)
     -# \ref FileSystem     - provides file system capabilities to TI's CC31XX that can be used by both the CC31XX device and the user.


 \section         proting_sec     Porting Guide

 The porting of the SimpleLink driver to any new platform is based on few simple steps.
 This guide takes you through this process step by step. Please follow the instructions
 carefully to avoid any problems during this process and to enable efficient and proper
 work with the device.
 Please notice that all modifications and porting adjustments of the driver should be
 made in the user.h header file only.
 Keep making any of the changes only in this file will ensure smoothly transaction to
 new versions of the driver at the future!


 \subsection     porting_step1   Step 1 - Create your own user.h file

 The first step is to create a user.h file that will include your configurations and
 adjustments. You can use the empty template provided as part of this driver or
 you can choose to base your file on file from one of the wide range of examples
 applications provided by Texas Instruments


 \subsection    porting_step2   Step 2 - Select the capabilities set required for your application

 Texas Instruments made a lot of efforts to build set of predefined capability sets that would
 fit most of the target application.
 It is recommended to try and choose one of this predefined capabilities set before going to
 build your own customized set. If you find compatible set you can skip the rest of this step.

 The available sets are:
     -# SL_TINY     -   Compatible to be used on platforms with very limited resources. Provides
                        the best in class foot print in terms of Code and Data consumption.
     -# SL_SMALL    -   Compatible to most common networking applications. Provide the most
                        common APIs with decent balance between code size, data size, functionality
                        and performances
     -# SL_FULL     -   Provide access to all SimpleLink functionalities


 \subsection    porting_step3   Step 3 - Bind the device enable/disable output line

 The enable/disable line (nHib) provide mechanism to enter the device into the least current
 consumption mode. This mode could be used when no traffic is required (tx/rx).
 when this line is not connected to any IO of the host this define should be left empty.
 Not connecting this line results in ability to start the driver only once.


 \subsection    porting_step4   Step 4 - Writing your interface communication driver

 The SimpleLink device support several standard communication protocol among SPI and
 UART. Depending on your needs and your hardware design, you should choose the
 communication channel type.
 The interface for this communication channel should include 4 simple access functions:
 -# open
 -# close
 -# read
 -# write

 The way this driver would be implemented is directly effecting the efficiency and
 the performances of the SimpleLink device on this platform.
 If your system has DMA you should consider to use it in order to increase the utilization
 of the communication channel
 If you have enough memory resources you should consider using a buffer to increase the
 efficiency of the write operations.


 \subsection     porting_step5   Step 5 - Choose your memory management model

 The SimpleLink driver support two memory models:
     -# Static (default)
     -# Dynamic

 If you choose to work in dynamic model you will have to provide alloc and free functions
 to be used by the Simple Link driver otherwise nothing need to be done.


 \subsection     porting_step6   Step 6 - OS adaptation

 The SimpleLink driver could run on two kind of platforms:
     -# Non-Os / Single Threaded (default)
     -# Multi-Threaded

 If you choose to work in multi-threaded environment under operating system you will have to
 provide some basic adaptation routines to allow the driver to protect access to resources
 for different threads (locking object) and to allow synchronization between threads (sync objects).
 In additional the driver support running without dedicated thread allocated solely to the simple
 link driver. If you choose to work in this mode, you should also supply a spawn method that
 will enable to run function on a temporary context.


 \subsection     porting_step7   Step 7 - Set your asynchronous event handlers routines

 The SimpleLink device generate asynchronous events in several situations.
 These asynchronous events could be masked.
 In order to catch these events you have to provide handler routines.
 Please notice that if you not provide a handler routine and the event is received,
 the driver will drop this event without any indication of this drop.


 \subsection     porting_step8   Step 8 - Run diagnostic tools to validate the correctness of your porting

 The driver is delivered with some porting diagnostic tools to simplify the porting validation process
 and to reduce issues latter. It is very important to follow carefully this process.

 The diagnostic process include:
     -# Validating Interface Communication Driver
     -# Validating OS adaptation layer
     -# Validating HW integrity
     -# Validating basic work with the device
