Post-Quantum Cryptography (PQC)

Attribute-Based Encryption Standard; Forward Looking PQC

Attribute-Based Encryption (ABE) has received two codified standards from the European Telecommunications Standards Institute (ETSI). This cryptographic system permits access to data based on a user’s crypto-key attributes vice the user per se. ABE’s compactness permits its use in CPU-constrained environments such as IoT devices. The specifications are said to enable integration of post-quantum computing-resistant encryption methods.

Authenticated Key Exchange: Ripe for Quantum Hacking

NIST’s post-quantum cryptographic efforts only go so far; while producing secure post-quantum computing algorithms, some cryptographic applications are left hanging. One concern is “…for software that relies on a sealing API to operate securely, there is no immediate post-quantum secure alternative to migrate to.”
