Cellular automata based key distribution for lightweight hybrid image encryption with elliptic curve cryptography.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The paper presents a lightweight hybrid image encryption scheme for IoT applications. The method performs secure key exchange using ECC, derives random keys using the CA Rule Vector [90, 90, 51, 51, 92, 195, 195, 195], and encrypts the image using AES-128. The secret shared via ECC serves as the seed for the CA rule vector [90, 90, 51, 51, 92, 195, 195, 195], facilitating the generation of a highly dispersed and secure session key. The system generates a highly diffused key through CA and then uses it in the AES encryption process. The framework has been tested on standard images from the SIPI database and has shown strong security results with NPCR of 99.6461, UACI of 49.9927, and entropy of 7.9991 for the Baboon Image. The method has passed all NIST randomness tests and shows a superior execution time, making it highly suitable for lightweight encryption in resource-constrained IoT environments.
