This exercise involves designing an enciphering and deciphering system using polling on the Zybo Z7 board. The system encrypts and decrypts messages using a simple cipher mapping function based on a shift key parameter.
- Objective: Design a software system that receives an original message for encryption or a ciphertext message for decryption from the SDK console terminal, encrypts or decrypts the input message, and sends the decoded message back to the console.
- Cipher Method: Each letter in the message is replaced with another letter according to the defined shift key parameter. For example, with a shift key of 2, "A" becomes "C" during encryption and vice versa during decryption.
- Example: Input message: "Vjg swkem dtqyp hqz lworu qxgt vjg ncba fqi." Output message: "The quick brown fox jumps over the lazy dog."
- Download the hardware configuration and software project from the folder
cipher_decipher. - Include the provided code files (
main_SDK.c,cipher_lookup_table.c,cipher_lookup_table.h) in the SDK project. - Load the hardware configuration from Vivado into SDK and open the provided software project.
- Run the software project to display the menu with two commands: encryption/encipher and decryption/decipher.
- Select the command (1 for encryption, 2 for decryption) by typing the corresponding number followed by Enter.
- Follow the prompts to enter the original message for encryption or the ciphertext message for decryption.
- The system will encrypt or decrypt the message and display the decoded result on the SDK console.
