Codes and cryptography

Codes and cryptography

Codes and cryptography address different aspects of security and reliability of information. While codes tend to deal with accidental interferences, cryptography addresses the scenario of deliberate tampering. Our research in this area spans the two disciplines, often making use of combinatorial and probabilistic methods. Some of our recent and ongoing research includes fingerprinting codes for digital content protection, private information retrieval in coded and uncoded databases, storage codes for resilience and reliability, and cryptographic key management techniques for distributed environments.
