HidX
HidX is a lightweight cryptographic protocol designed to provide secure data transmission in resource‑constrained environments such as Internet of Things (IoT) devices, medical implants, and low‑power sensors. It was introduced in 2020 by the Secure Networks Research Group at the Institute of Advanced Computing. The protocol builds on the concept of authenticated encryption with associated data (AEAD) but optimizes for minimal memory usage and single‑bit‑level reliability.
The core of HidX is a stream‑cipher based on a 128‑bit key and a 96‑bit nonce. The
Implementation of HidX is available in several programming languages, including C, Rust, and JavaScript. The reference
Several security analyses have confirmed that HidX withstands chosen‑plaintext attacks and differential cryptanalysis within the stated
