The document outlines the design and implementation of a Triple DES (3DES) encryption system by a team consisting of Junjie Wang, Xiao Xiao, Zhuofan Li, and Ming Huen Lee. It covers the algorithm's operation, system architecture, success criteria for design validation, and details on pipelining and output requirements. Additionally, various design-specific success criteria are provided, along with challenges and improvements for enhanced security.

2. Overview - What is 3DES?
Users are able encrypt / decrypt data in a secure way
Prevent hacking into important data
Algorithm applies Data Encryption Standard (DES) 3 times
Ciphertext = EK3(DK2(EK1(plaintext)))
Each DES has 16 rounds of processing -> Encrypted with 56-bit key
Appropriate for ASIC design
Less time delay
Consume less power
Data will send through avalon bus to the FPGA 2

design specific success criteria. (2 pts/Achieved)
2. Entire design synthesizes completely, without any inferred latches, timing arcs, and, sensitivity list
warnings (4 pts/Achieved)
3. Source and mapped version of the complete design behave the same for all test cases. The mapped
version simulates without timing errors except at time zero (2 pts/Achieved)
4. A complete IC layout is produced that passes all geometry and connectivity checks (2 pts)
5. The entire design complies with targets for area, pin count, throughput (if applicable), and clock rate.
