The first part of this book covers the key concepts of cryptography on an undergraduate level, from encryption and digital signatures to cryptographic protocols. Essential techniques are demonstrated in protocols for key exchange, user identification, electronic elections and digital cash. In the second part, more advanced topics are addressed, such as the bit security of one-way functions and computationally perfect pseudorandom bit generators. The security of cryptographic schemes is a central topic. Typical examples of provably secure encryption and signature schemes and their security proofs are given. Though particular attention is given to the mathematical foundations, no special background in mathematics is presumed. The necessary algebra, number theory and probability theory are included in the appendix. Each chapter closes with a collection of exercises. In the second edition the authors added a complete description of the AES, an extended section on cryptographic hash functions, and new sections on random oracle proofs and public-key encryption schemes that are provably secure against adaptively-chosen-ciphertext attacks. The third edition is a further substantive extension, with new topics added, including: elliptic curve cryptography; Paillier encryption; quantum cryptography; the new SHA-3 standard for cryptographic hash functions; a considerably extended section on electronic elections and Internet voting; mix nets; and zero-knowledge proofs of shuffles. The book is appropriate for undergraduate and graduate students in computer science, mathematics, and engineering.

This book is dedicated to the development of a sophisticated and feature-rich Tkinter GUI that leverages Elliptic Curve Cryptography (ECC) for various cryptographic operations, including key generation, encryption, decryption, signing, and verifying data. The primary goal is to create an interactive application that allows users to perform these operations on synthetic financial data, demonstrating the practical use of ECC in securing sensitive information. The GUI is meticulously designed with multiple tabs, each corresponding to a different cryptographic function, enabling users to navigate through key generation, data encryption/decryption, and digital signature processes seamlessly. The GUI starts with the key generation tab, where users can generate ECC key pairs. These key pairs are essential for the subsequent encryption and signing operations. The GUI provides feedback on the generated keys, displaying the public and private keys in hexadecimal format. This feature is crucial for understanding the foundational role of ECC in modern cryptography, where small key sizes provide strong security. The key generation process also highlights the advantages of ECC over traditional RSA, particularly in terms of efficiency and security per bit length. In the encryption and decryption tab, the GUI enables users to encrypt synthetic financial data using the previously generated ECC keys. The encryption process is performed using AES in Cipher Feedback (CFB) mode, with the AES key derived from the ECC private key through key derivation functions. This setup showcases the hybrid approach where ECC is used for key exchange or key derivation, and AES is employed for the actual encryption of data. The GUI displays the generated ciphertext in a hexadecimal format, along with the Initialization Vector (IV) used in the encryption process, providing a clear view of how the encrypted data is structured. The signing and verifying tab demonstrates the use of ECC for digital signatures. Here, users can sign the synthetic financial data using the ECDSA (Elliptic Curve Digital Signature Algorithm), a widely recognized algorithm for ensuring data integrity and authenticity. The GUI displays the generated digital signature in hexadecimal format, offering insights into how ECC is applied in real-world scenarios like secure messaging and digital certificates. The verification process, where the signature is checked against the original data using the ECC public key, is also integrated into the GUI, emphasizing the importance of digital signatures in verifying data authenticity. The synthetic financial data used in these operations is generated within the GUI, simulating transaction records that include fields such as transaction ID, account number, amount, currency, timestamp, and transaction type. This dataset is crucial for demonstrating the encryption and signing processes in a context that mirrors real-world financial systems. By encrypting and signing this data, users can understand how ECC can be applied to protect sensitive information in financial transactions, ensuring both confidentiality and integrity. Finally, the GUI’s design incorporates user-friendly elements such as scrolled text widgets for displaying long hexadecimal outputs, entry fields for user inputs, and clear labels for guiding the user through each cryptographic operation. The application provides a comprehensive and interactive learning experience, allowing users to explore the intricacies of ECC in a controlled environment. By integrating ECC with AES for encryption and ECDSA for signing, the GUI offers a practical demonstration of how modern cryptographic techniques can be combined to secure data, making it an invaluable tool for anyone looking to understand or teach the principles of ECC-based cryptography.

This is a graduate textbook of advanced tutorials on the theory of cryptography and computational complexity. In particular, the chapters explain aspects of garbled circuits, public-key cryptography, pseudorandom functions, one-way functions, homomorphic encryption, the simulation proof technique, and the complexity of differential privacy. Most chapters progress methodically through motivations, foundations, definitions, major results, issues surrounding feasibility, surveys of recent developments, and suggestions for further study. This book honors Professor Oded Goldreich, a pioneering scientist, educator, and mentor. Oded was instrumental in laying down the foundations of cryptography, and he inspired the contributing authors, Benny Applebaum, Boaz Barak, Andrej Bogdanov, Iftach Haitner, Shai Halevi, Yehuda Lindell, Alon Rosen, and Salil Vadhan, themselves leading researchers on the theory of cryptography and computational complexity. The book is appropriate for graduate tutorials and seminars, and for self-study by experienced researchers, assuming prior knowledge of the theory of cryptography.
