Security in Communications and Storage

What it is about

You learn methods and concepts to achieve security in communication and storage systems. The module covers classical and post-quantum cryptography, error-correcting codes and their application in distributed data storage, as well as Private Information Retrieval; in the end you will be able to understand, evaluate and practically apply these schemes.

What you will be able to do

• Name and explain measures for security in modern communication and storage systems
• understand and analyze fundamental cryptographic schemes
• name challenges of Post-Quantum Cryptography
• choose codes suitable for code-based cryptography, adjust parameters, evaluate and implement
• understand and implement known attacks on code-based cryptography
• give an overview of symmetric cryptography and authentication
• explain the most important codes for distributed data storage
• identify design challenges and parameter interactions in distributed data storage
• identify security problems in distributed data storage
• understand the principle and forms of Private Information Retrieval
• provide an overview of complexity, capacity and codes in Private Information Retrieval
