Confluent Cloud’s Path to Post-Quantum Cryptography

Confluent is actively preparing for a future where quantum computers could potentially compromise current cryptographic algorithms by aligning with the latest National Institute of Standards and Technology (NIST) Federal Information Processing Standards (FIPS) to develop a post-quantum cryptographic infrastructure. This preparation includes enhancing data-in-transit encryption by implementing TLS 1.3 as a standard and adopting a hybrid key exchange model that combines classical and quantum-resistant algorithms. For data-at-rest encryption, Confluent is relying on 256-bit symmetric cryptography, which is considered secure in the quantum era, and is exploring additional support for PQC-compliant keys, especially in Microsoft Azure environments. Confluent emphasizes the shared responsibility for security between themselves and their customers, ensuring that the latest post-quantum cryptographic features are accessible either by default or as optional enhancements. Additionally, the text briefly introduces the Kafka Copy Paste tool, which facilitates rapid migration to Confluent Cloud.
