51 Security Terminology WEP - This is the name given to the encryption scheme originally specified for bit and 128-bit encryption –WEP is being replaced due to the following flaws: –Changing keys is a nuisance. –Very easy to crack. There are several free programs available on the Internet. WPA - The protocol implements the majority of the IEEE i standard, and was intended as an intermediate measure to take the place of WEP while i was prepared. Specifically, (TKIP), was brought into WPA.IEEE i WPA2 - Replaced WPA and implements the mandatory elements of i. In particular, it introduces a new AES-based algorithm, CCMP, which is considered fully secure. WPA2 certification is mandatory for all new devices to bear the Wi-Fi trademark iAESCCMP WPA- and WPA2- Enterprise - The Wi-Fi alliance recognizes EAP (Extensible Authentication Protocol) types to its certification programs for WPA- and WPA2- Enterprise certification programs. This was to ensure that WPA-Enterprise certified products can interoperate with one another. Previously, only EAP-TLS (Transport Layer Security) was certified by the Wi-Fi alliance.Extensible Authentication ProtocolTransport Layer Security The EAP types now included in the certification program are: –EAP-TLSEAP-TLS –EAP-TTLS/MSCHAPv2EAP-TTLS –PEAPv0/EAP-MSCHAPv2PEAPv –PEAPv1/EAP-GTC –EAP-SIMEAP-SIM

52 Wireless Network Modes Ad-hoc mode - Wireless devices communicate directly with each other. Also referred to as peer-to-peer mode. Infrastructure mode - Wireless devices communicate with each other by first going through an access point. This framework is most commonly used when provided access to a wired network.

53 Web development Simplified Develop feature rich web applications on a Rabbit Core Module by utilizing proprietary RabbitWeb scripting extensions as well as the Yahoo! User Interface libraries. Utilize the Model-View-Controller (MVC) design pattern to simplify development and to illustrate building a richly interactive web application as seen below.

54 Libraries Needed #memmap xmem compiles all functions to xmem – Good for TCP/IP programs – Large TCP/IP functions can fill root code area #use “http.lib” includes the web server #use “dcrtcp.lib” Includes main TCP/IP libraries – Must be present in all TCP/IP programs – Configuration macros (TCP buffer sizes, etc.) must occur before this statement #use “xbee.lib” includes customized library from Application Kit #memmap xmem #use "dcrtcp.lib" #use "http.lib" #use "xbee.lib" #memmap xmem #use "dcrtcp.lib" #use "http.lib" #use "xbee.lib"

55 HTTP Server Library HTTP/1.0 Implementation – Works with all major browsers Serves both static and dynamic content – CGI functions and RabbitWeb assist with dynamic content Filesystem support Authentication (basic, digest) supported HTTPS support with added module

56 HTTP Server Library Static content is defined in compile-time data structures – Resource table – MIME types table Content can also be added and removed at run-time ZServer.lib manages resources for the HTTP and FTP servers – Provides abstraction layer

57 Yahoo! User Interface Library The YUI library is a set of utilities and controls, written in JavaScript, for building feature rich web interfaces.

58 CGI Support For dynamic content, Common Gateway Interface (CGI) functions can be used When a CGI resource is loaded by the browser, the server gives control to a callback function The callback function has complete control of the HTTP socket Very flexible, but difficult to code RabbitWeb provides a simpler model

59 CGI Basics CGI functions. CGI stands for “Common Gateway Interface,” however this acronym has a more specific use in Dynamic C— Refers to a C function that is called by the HTTP server to generate some dynamic content for the browser. This is the only truly optional block. Many applications can be written without resorting to CGI functions; however, there are some cases where the power and flexibility of a CGI will be required.

60 CGI Functions Use of the HttpState structure is necessary for CGI functions CGI is a standard for interfacing external applications with HTTP servers. Each time a client requests an URL corresponding to a CGI program, the server will execute the CGI program in real-time. int nodeDiscover_cgi(HttpState* s); int terminal_cgi(HttpState* s); int dioRead_cgi(HttpState* s); int dioWrite_cgi(HttpState* s); int nodeDiscover_cgi(HttpState* s); int terminal_cgi(HttpState* s); int dioRead_cgi(HttpState* s); int dioWrite_cgi(HttpState* s);

61 RabbitWeb Goals Ease the chore of creating web interfaces Enable choices about presentation tobe made in the HTML files, not code Retain flexibility of web page design Leverage web designers’ existing knowledge Take ideas from server-oriented realm (e.g., PHP, ASP) and refashion to be appropriate to small embedded systems

62 Solution Develop light HTML scripting language (ZHTML) Link variables in ZHTML with C variables Enable simple error-checking of user input Use ZHTML to report errors in user input Restrict updates to specific users Allow callbacks to be executed on user input

63 Bringing in Rabbit Web RabbitWeb can reduce weeks or months of complex Common Gateway Interface (CGI) programming down to hours. Using RabbitWeb eliminates the need for CGI programming by handling the association of web variables to C variables and even allows for callback functions to be triggered when web variables are changed. RabbitWeb is an ideal tool for simplifying the development of dynamic web interfaces. {"myIO":[ 0) { ?>, {"index":, "port":" ", "bit":, "type":, "value":, "name":" } ]}

64 RabbitWeb Compiler Extensions #web directive registers variables C variable must have been previously declared Optional error-checking expression (guard) Optional “groups=” parameter imposes security limits { struct struct // AT COMMAND OPTIONS { int ct,gt,cc;// txtBox { int ct,gt,cc;// txtBox int on,off;// button(writeOnly) int on,off;// button(writeOnly) }at;// AT Command Options }at;// AT Command Options}xb_type; void atCallBack();// callback function for at option changes #web xB.at.ct (((2 <= $xB.at.ct) && ($xB.at.ct <= 0x028F))?1:ERR(NULL)) #web xB.at.gt (((1 <= $xB.at.gt) && ($xB.at.gt <= 0x0CE4))?1:ERR(NULL)) #web xB.at.cc // text box(0-0xFF) #web xB.at.on (xb_atModeOn(xB.at.gt)>0?1:WEB_ERROR("on")) #web_update xB.at.ct,xB.at.gt,xB.at.ccatCallBack { struct struct // AT COMMAND OPTIONS { int ct,gt,cc;// txtBox { int ct,gt,cc;// txtBox int on,off;// button(writeOnly) int on,off;// button(writeOnly) }at;// AT Command Options }at;// AT Command Options}xb_type; void atCallBack();// callback function for at option changes #web xB.at.ct (((2 <= $xB.at.ct) && ($xB.at.ct <= 0x028F))?1:ERR(NULL)) #web xB.at.gt (((1 <= $xB.at.gt) && ($xB.at.gt <= 0x0CE4))?1:ERR(NULL)) #web xB.at.cc // text box(0-0xFF) #web xB.at.on (xb_atModeOn(xB.at.gt)>0?1:WEB_ERROR("on")) #web_update xB.at.ct,xB.at.gt,xB.at.ccatCallBack

75 PAN Network Formation –Coordinator must select an unused operating channel and PAN ID Energy scan on all channels Sends Beacon request (Broadcast PAN ID) Listens to all responses and logs the results –After the Coordinator has started, it will allow nodes to join to it for a time based on the specified Node Join Time ZigBee Protocol

76 Coordinator –Picks PAN ID –Picks Channel –Assigns Addresses –Allows nodes to join network

77 Coordinator –Picks Channel & PAN ID ZigBee Protocol

78 Router Startup –A new Router must locate a Router that has already joined a PAN or a Coordinator Sends a Broadcast PAN ID on each channel Returns sent via unicast –Router will then try to join to a Router or Coordinator that is allowing joining ZigBee Protocol

79 End node: Low-power Sleep Modes End Node Startup –A new End node must locate a Router that has already joined a PAN or a Coordinator Sends a Broadcast PAN ID on each channel Returns sent via unicast –End node will then try to join to a parent (Router or Coordinator) that is allowing joining ZigBee Protocol

81 Setting Up a New ZigBee Network –A new Router must locate a Router that has already joined a PAN or a Coordinator –End Devices join a coordinator or other router. –End Devices cannot join to other end devices ZigBee Protocol

82 ZigBee Addressing –64-bit IEEE “Extended Address” Set by manufacturer – permanent address –16-bit “Network Address” Set by parent – can change ZigBee Protocol

83 Details of the Demo Overview –ZigBee & Using Dynamic C XBee API –Utilizes the BL4S100 to act as the gateway –Web interface to a ZigBee Network Using RabbitWeb Using Yahoo! User Interface Library 3 rd party tools for debugging

84 BL4S100 ZigBee Network Monitor In order to determine if a router has been powered off, routers will send a heartbeat every ~4 seconds. When the Coordinator receives the heartbeat it updates a time- to-live variable for that router. –This TTL is checked by the coordinator every 12 seconds and if it has been expired the router or end device image is removed. The web interface will automatically and seamlessly update every 1 second.

85 BL4S100 ZigBee Control Web interface is used to control I/O of routers and end devices Can also monitor if routers are on and whether a button has been pressed
