Cryptography and Network Security is an important domain in computer science that focuses on securing communication and protecting information from unauthorized access. The proposed Cryptography Virtual Lab helps students understand and visualize the working principles of modern cryptographic algorithms and protocols. The lab provides interactive simulations that demonstrate the internal operations of algorithms such as DES, AES, Twofish, ElGamal, and Elliptic Curve Diffie–Hellman (ECDH). Through these visualizations, students can observe the step-by-step processes of key generation, encryption, decryption, and secure key exchange, which enhances conceptual understanding of cryptographic techniques used in real-world secure communication systems.
The objective of this lab is to help students understand the concepts and internal workings of symmetric and asymmetric cryptographic algorithms. The lab enables students to explore DES and AES key generation, encryption, and decryption processes, understand the encryption and decryption mechanisms of the Twofish algorithm, and learn public key cryptography through ElGamal and the Elliptic Curve Diffie–Hellman key exchange protocol. Through simulation-based learning, students gain practical insight into how cryptographic systems secure data and communications.
