Advanced Public Key Cryptography
Overview
In the past three decades cryptography has taken on tasks above and beyond the basic task of securing point-to-point communication channels: Maintaining the privacy of individuals in databases, secure computation on large datasets and anonymous transactions in blockchains-based currencies to name just a few.
This course will cover the state-of-the-art in public-key encryption and discuss some of the guiding challenges and frontier-problems of today.
The following topics will be covered:
- Modelling Security for public-key encryption
- Proving security of public-key encryption schemes
- Tools for building public-key encryption schemes
- Notions of public-key encryption with enhanced functionality:
Homomorphic Encryption
Identity-Based Encryption
Attribute-Based Encryption
Functional Encryption
