The US Defense Advanced Research Projects Agency (DARPA) Small Business Programs Office (SBPO) has called for research concept submissions in Cryptography for Hyper-scale Architectures in a Robust Internet of Things (CHARIOT). The objective of the project is to develop approaches for fast, efficient, and quantum-resistant cryptographic operations for Internet of things (IoT) devices. The aim will be to create a prototype of low-cost, low footprint, post-quantum cryptographic techniques with minimal energy use for IoT devices. This call will open for proposals until 29 September 2020.
