SELAM Cuts IoMT Authentication Computation 99.6% and Communication 20%

Summary
A new IoMT authentication framework, SELAM, reduced online computation to 0.10 ms per device from 23.59 ms in an ECC-heavy baseline, while lowering payload communication to 6,144 bits from 7,680 bits.
The gain comes from confining elliptic-curve cryptography to one-time user and device registration, then using hash/HMAC, XOR, timestamps and KDF-derived session keys during online authentication.
At 1 Mb/s, SELAM cut total per-device authentication overhead to 6.24 ms from 31.27 ms; in ns-3 tests with 136 devices, header-inclusive traffic fell to 39,416 bits per device versus 45,703.
Across 136 to 2,000 devices over 20 simulation seeds, SELAM kept attack-regime authentication success at 0.88 to 0.90 versus 0.90 to 0.92 for the baseline, with protocol-level FAR and benign FRR both at zero.
The study positions SELAM as a lightweight option for resource-constrained medical devices in an IoMT market projected to exceed $187 billion by 2028, though it does not claim perfect forward secrecy.

SELAM’s 99.6% Efficiency Breakthrough: Transforming IoMT Authentication for Secure, Low-Power Medical Devices
Overview
This report highlights SELAM, a new system designed to improve security for the Internet of Medical Things (IoMT). SELAM claims to reduce computational cost for authentication by 99.6% and cut communication overhead by 20%. These efficiency gains could greatly enhance the performance of medical devices by reducing processing delays and improving battery life. As IoT usage grows, security challenges increase, making it crucial to protect privacy and ensure the safety of users and data. Highly efficient authentication mechanisms like SELAM represent a major step forward in addressing these challenges for connected medical devices.
