Question
[画像:Step 1: Encryption Algorithm Implementation Choose one symmetric encryption algorithm from the following list: AES, DES, IDEA, Blowfish, RC4, RC5, or RC6. Provide a brief overview of the algorithm, including its history, key features, and typical use cases. Implement the chosen encryption algorithm (in any language you wish). Do NOT use a library or package that already has an implementation of the encryption algorithm in question. NOTE: IT IS NOT THE NORM TO CREATE YOUR OWN IMPLEMENTATION OF AN ENCYRPTION ALGORITHM. THIS IS FOR LEARNING PURPOSES ONLY. IT IS CONSIDERED HIGHLY INSECURE TO DO THIS IN A REAL-WORLD APPLICATION BECAUSE YOUR IMPLEMENTATION MIGHT BE FLAWED. Step 2: Message Encryption Create a plaintext message that will be encrypted. The message should be meaningful and at least 100 characters long. Encrypt the plaintext message using the chosen algorithm, resulting in ciphertext. Step 3: Simulated Network Transmission: Set up a simple client-server architecture using socket programming, where one program acts as the sender (client) and the other as the receiver (server). The sender should encrypt the message and send the ciphertext over the network to the receiver. The receiver should accept the incoming message and store the ciphertext. Step 4: Verification and Analysis: Decrypt the received ciphertext at the receiver's end and verify that it matches the original plaintext message. Conduct a security analysis of the chosen encryption algorithm, discussing its strengths, potential vulnerabilities, and how it compares to other algorithms in the list. Step 5: Documentation and Reporting: Document the encryption algorithm implementation, including a detailed explanation of the algorithm's workings and your rationale for any specific configurations or modes used. Describe the network transmission simulation process, highlighting any challenges encountered and their solutions. Discuss the decryption and verification process, along with the results of your security analysis.]
