Lab Testing User Interface
For housing services, compare the three websites
http://www.housingmaps.com
http://www.urmap.com.tw/asp/kijiji/
http://www.7house.com.tw
List the differences in the user interface design and usability. Make comments
by your use experiences.

Lab Google Mars (AJAX)
1. Observe how Google Mars loads the map and does the zooming. Is the data downloaded once
for all or retrieved on demand?
2. HTML alone cannot perform the functions of Google Mars. So find out which code in the HTML
source does the map things.
Hints: You may use Nvu to determine what HTML tags are for what.

Lab Simple Use of Web Service
"we make a living by what we get, we make a life by what we give"
Test Drive a web service
1. Take a look at the schema of Zip Code Web Service.
2. Use the lincense key eUhOTOJs9D2mcHU6SiL0CyMQvpJ3I3PqR2/fpRq4BOApWxzSzw7wD2FQ2mOmHEk+pq6iRBomQ4wuQl5EGOgfCitYgkQ3N4vl
to use this web service or subsbcribe to it at Zip codes lookup To apply for the license key by yourselves, be sure to have an email box to receive it.
2. Click GetPlacesInside and play with this operation
3. Enter 61801 as zip code and see what you get in the result.
4. Try again 92345 as zip code
Question: Why do you need a license key to use the service?

What is SOAP?
SOAP is the Simple Object Access Protocol. It is used for information exchange and RPC, usually (but not necessarily) over HTTP. More information can be found at:
Developmentor SOAP FAQ: http://www.soaprpc.com/faqs/SoapFAQ.html
W3C specifications: http://www.w3.org/TR/SOAP/
What is WSDL?
WSDL is the Web Service Description Language. It provides a formal description of a web service, much like CORBA's IDL. The WSDL file is all you need to know how to call the web service; toolkits can generate proxy code from a WSDL file directly. The official WSDL definition is at http://www.w3.org/TR/wsdl.

Lab SSL
1. Try Yam membership enrollment
for using SSL encrypted Internet communications.
2. Note the lock at the lower right corner is secured when SSL is enabled.
3. Click the lock icon and a message window should pop up.
4. What kind of encryption is used in this SSL? How many bits are there in the encryption key?
5. Who issued the certificate you are seeing? (Who is the certificate authority, CA, for this website?)
6. Until when is the certificate valid?
7. What kind(s) of hash is/are used in the CA's digital signature?
8. How many bits are there in the hash(es)?

Lecture on network secutiry and the theory of public key
(Chapter 3 of Textbook)
Secrect Key
*a key for encryption is also for decryption
*fast encryption and decryption
*problem with key distribution
*problem with keeping many keys
Public Key
*private key and public key
*public usually posted on an open directory
*private key must be kept in absolute private to oneself
*good for encryption and signature
Hash function
*fixed length of 128 or 256 bits
*fingerprint
do Lab Hash
Digital Signature
* privated key encrypted fingerprint of a plain text
*transmitted along with the plain text for verification
Man-in-the-middle attack
Digital Certificate
* Public Key signed with Certificate Authority
SSL (Secure Socket Layer)
* Using Digital Certificate, Digital Signature, Public Key Encryption, Hash (Message Digest)
* Instead of encrypting the sender's original text, only the session key generated by the sender is encrypted by the receiver's public key.
* The session key is valid throughout a session and not any longer.
* SSL is proposed by Netscape, Inc.
* https is actually http enhanced by SSL. https uses port 443 while http uses port 80.
