A Secure and Robust Blockchain‐Based Medical Image Encryption Approach Using Lorenz Chaotic System
Keeping medical images confidential while transmitting is crucial, especially in an open networking environment. One effective approach is blockchain‐based encryption, which provides strong security for sensitive healthcare data. To ensure the greatest levels of medical data integrity and authenticity, our proposed scheme employs a unique Lorenz ...

Security evaluation, NPCR + UACI results of 99.5978% and 33.4549% respectively, confirm the system is secure against statistical and differential attacks. Besides, the FPGA implementation achieves low power of 115 mW at a speed of 42.56 MHz. This makes it suitable for IoT applications where power and hardware resources are constrained. ABSTRACT In this

Automated Risk‐Based Cryptoperiod Calculation in ICSs: Analytical Framework and Software Tool
ABSTRACT Internal network and system reconnaissance is one of the first crucial stages of most cyber attacks, though it plays an especially important role in attacks on complex industrial control systems (ICSs) that span both IT and OT environments. Frequently, besides device enumeration and scanning, a malicious ICS reconnaissance campaign will also ...

A Meaningful MD5 Hash Collision Attack [PDF]
It is now proved by Wang et al., that MD5 hash is no more secure, after they proposed an attack that would generate two different messages that gives the same MD5 sum. Many conditions need to be satisfied to attain this collision.
