Explores message authentication codes and their formalism, with a focus on mobile telephony, covering topics like misuse attacks, security notions, and GSM architecture.
Explores homomorphic encryption, its applications, challenges, and comparisons with Trusted Execution Environments, as well as the use of aggregated keys for secure data sharing.
Explores the physical limits and security aspects of symmetric encryption schemes, including energy consumption, key recovery, and distinguisher security.
Explores symmetric cryptography for integrity, emphasizing Message Authentication Codes and different encryption approaches to ensure data confidentiality and integrity.
Introduces secret key cryptography, covering 'one-time pad' encryption, flaws in key sharing, and the Data Encryption Standard (DES) principles and operation.
