Hello,
My name is Beatrice Fankem, SimpleLink Wi-Fi Product Marketing Engineer.
The Internet of Things (IoT) is becoming an increasingly large part of our everyday life. There are several challenges that must be addressed when designing a product that can be remotely monitored or controlled. In this session, we will address how Simplelink Wi-Fi and Xively partnered to tackle those core challenges.

2. Enabling technology in many markets

The Nodes are the devices we use to collect information or control things
A typical device will have an MCU or Processor, Power Management, Sensors and Analog and Connectivity
They may require small size
They may require long battery life, may often be ”sleeping” – only waking up when something happens
May use a wide range of sensors depending on application – medical, gas, etc
The Gateways are used to bridge between the nodes and internet
Will contain at least 2 technologies – a protocol to connect to the nodes and one for the internet – such as ethernet or WiFI.
The Cloud is where the information is stored, processed into analytics and where commands can be sent back to the nodes or interface with a Smartphone
The Cloud servers need to be always on and perform parallel processing and handle mass storage

12. Internet Security - Made Easy
Unsecured socket connection
Secured socket connection
SlSockAddrIn_t Address;
int SockID;
Address.sin_family = SL_AF_INET;
Address.sin_port = sl_Htons(PORT);
Address.sin_addr.s_addr = sl_Htonl(IP_ADDRESS);
SockID = sl_Socket(SL_AF_INET, SL_SOCK_STREAM, 0);
sl_Connect(SockID, ( SlSockAddr_t *)&Address, sizeof(SlSockAddrIn_t));
SockID = sl_Socket(SL_AF_INET, SL_SOCK_STREAM, SL_SEC_SOCKET);
The protocol family of the socket
Ex. AF_INET for IPv4
IPv4 AF_RF for transceiver mode

13. Software Development Examples
HTTP client
Provisioning using AP mode
XMPP
MQTT
SMTP
Secured sockets
Sensors using I2C
Audio using I2S

Notes for on chip Security
WPA2 – WiFi Protected Access 2 is the latest WiFi security standard. It has a personal option for home use and an enterprise option that includes user authentication with a security server.
EAP XXXXX are different user authentication methods used by the WPA2 enterprise standard.
802.1x is the IEEE network authentication protocol that is used by WPA2 enterprise
WPS2 – Wi-Fi Protected Setup – is the Wi-Fi standard for easy Wi-Fi provisioning using a push button on the access point or a PIN code
Notes for Internet Security
SSL 3.0 – Secured Socket Layer – is the most used internet application security protocol (e.g. in web HTTPS applications)
TLS 1.2 – Transport Layer Security – is a new standard replacing SSL 3.0. It has improved security over SSL3.0.
X.509 – ITU-T standard for public key infrastructure and certificate format, being used by SSL3.0 and TLS 1.2
DES3 – Data Inscription Standard 3 – old standard used for data encryption
AES256 – Advanced Encryption standard using 256 bity key length. Industry standard encryption at “top secret” level.
MD5 – Message Digest 5 – old standard for message hash / digital signature
SHA2 – Secure Hash Algorithm – industry standard for message / digital signature
RSA – Rivest-Shamir-Adelman – world’s golden cipher for public key cryptography
ECC – Elliptic Curve Cryptography – A new public key cryptography scheme that required less computation effort vs RSA
HW encryption engines establish
TLS/SSL connection in less than 200mSec
