This publication constitutes the refereed court cases of the eighth foreign convention on Web-Based studying, ICWL 2009, held in Aachen, Germany, in August 2009.

The 38 revised complete papers and 14 brief papers are offered including 3 invited papers and have been conscientiously reviewed and chosen from 106 submissions. They care for subject matters comparable to know-how more advantageous studying, web-based studying for oriental languages, cellular studying, social software program and net 2.0 for know-how improved studying, studying source deployment, association and administration, layout, version and framework of E-learning platforms, e-learning metadata and criteria, academic gaming and multimedia storytelling for studying, in addition to perform and event sharing and pedagogical Issues.

The words of the second five-word buffer are labeled H0, H1, H2, H3, and H4. The words of the 80-word sequence are labeled W(0), W(1), …, W(79). A single-word buffer, TEMP, is also employed. 3 Predefined Functions and Constants To describe the hash computation method, the following predefined set of functions and constants is required: Ⅲ A sequence of logical functions f(0), f(1), …, f(79) is used.

Alice and Bob agree upon a prime number p and a primitive root g. Alice generates a random number x, calculates A = gx mod p, and sends this to Bob. Bob also generates a random number y, calculates B = gy mod p, and sends this to Alice. Now Alice calculates gxy mod p and Bob does the same. The shared key is gxy mod p. An attacker only gets to know the numbers g, p, A, and B but not x and y. The attacker needs x and y to compute the key. The Diffie–Hellman problem is based on the difficulty of calculating discrete logarithms, so it is not possible to calculate x from A, p, and g, or y from B, p, and g.

For example, 11 ÷ 4 is 2 remainder 3; therefore, 11 mod 4 would be equal to 3. Once the encrypting variable is produced from the key setup, it enters the ciphering phase, where it is XORed with the plaintext message to create an encrypted message. Once the receiver gets the encrypted message, he or she decrypts it by XORing it with the same encrypting variable. 2 Common Use RC4 is widely used in commercial applications including Oracle SQL, Microsoft Windows, PERL, and the SSL technology (Chapter 8) for both file encryption and secure communication over the network, including Wireless LANs (WLANs).
