Mr. Bipin S. Rupadiya

Subject Name: Programming Skills – VI (FON)
Subject Code: 640011

List of Practicals:

1. Framing Techniques 
• Character Count
• Byte Stuffing
• Bit Stuffing
2. Error Detection and Correction Techniques 
• Single Bit Parity
• Block Parity
• Checksum
• CRC Checksum, 
• Hamming Code
• Note: Students may be asked to simulate different noise scenarios like single bit corruption, multi-bit corruption, etc, and check whether the receiver, using the given error detection/correction technique, is able to detect/correct the error. 
3. All Data Link Layer Protocols 
• Protocol 1
• Protocol 2
• Protocol 3
• Protocol 4
• Protocol 5
• Protocol 6 
• Note: 
• Provide Solution as per Main reference Book
• Protocols 1, 2 and 3 may be asked to be implemented completely. 
• Programs based on protocol 4, 5, and 6 may be asked in a way that a small feature like retransmission timer, or NACK or sliding window to be implemented. 
• Entire protocol programs must not be asked for protocol 4, 5 and 6. 
4. Cryptography (Without using Java Security/Cryptography Packages) 
• Java socket programming
• Simple Java socket example
• A complex Java socket programing demo
• Generalized Caesar Cipher
• Mono-alphabetic Substitution Cipher
• Transposition (Columnar) cipher
• P-Box 
• S-Box 
• Product Cipher 
• One Time Pad.
• Note: 
• Above programs in item no. 4 should be implemented in Java. 
• For these programs, students need to implement the corresponding algorithms themselves in Java. 
• Communication may be done using sockets. For that Java socket programming is to be used. 
5. Cryptography (using Java Security/Cryptography Packages) 
• Symmetric Block Ciphers: 
• DES 
• DES with ECB mode
• DES with CBC mode
• DES with CFM mode
• 3DES 
• 3DES with ECB mode
• 3DES with CBC mode 
• 3DES with CFM mode 
• AES   
• AES with ECB mode
• AES with CBC mode
• AES with CFM mode
• Stream Cipher 
• DES 
• 3DES
• AES  
• Asymmetric Ciphers: 
• RSA
• Note:
• For above programs in item no. 5, cryptography and security related Java packages like java.security, java.security.interfaces, java.security.spec, etc. should be used. 
• Students are NOT required to implement the actual logic of the cryptographic algorithm. Instead, the available security package API should be used. 
• Communication may be done using sockets. For that Java socket programming is to be used.
