“…It accepts any size input (or message) and generates a fixed-size 256-bit hash value that provides a unique representation of the original data. Several sophisticated procedures are involved in this process, including message padding, parsing, and multiple rounds of mathematical computations (Rawal, Kumar, Maganti, & Godha, 2022). Bitwise rotations, modular additions, and logical functions are among the essential operations.…”

Bluetooth communication enables effective data sharing for a wide range of applications, from audio streaming to IoT devices, boosting user ease and productivity. Bluetooth security difficulties stem from flaws in encryption mechanisms, which could allow unauthorized access or data interception. Current flaws include vulnerability to eavesdropping and device spoofing, emphasizing the need for improved security measures. The hybrid encryption technique suggested in this paper is a tribute to unprecedented innovation in Bluetooth security. It pioneers a multi-layered approach to data protection by seamlessly integrating AES, Blowfish, RSA, and SHA-256. This algorithm not only answers current security concerns, but it also teaches how to use cryptographic approaches strategically. Furthermore, its prudent use of RSA, which minimizes computing overhead, demonstrates a forward-thinking approach to combining security and efficiency. The algorithm's astounding great accuracy after multiple tests demonstrates its practical practicality, confirming its potential to transform Bluetooth security procedures. This effort establishes a new cryptographic standard, altering the landscape of wireless communication security.

“…These functions work in a deterministic fashion but generate pseudo-random results, making the computation of the algorithm the only feasible way to obtain the output hash (also called digest). A hash function is considered secure if it exhibits the properties of being one-way and collision-resistant [2]. Therefore, these functions require significant computational resources to process the input data and produce the correct output hash.…”

The growth of digital communications has driven the development of numerous cryptographic methods for secure data transfer and storage. The SHA-256 algorithm is a cryptographic hash function widely used for validating data authenticity, identity, and integrity. The inherent SHA-256 computational overhead has motivated the search for more efficient hardware solutions, such as application-specific integrated circuits (ASICs). This work presents a custom ASIC hardware accelerator for the SHA-256 algorithm entirely created using open-source electronic design automation tools. The integrated circuit was synthesized using SkyWater SKY130 130 nm process technology through the OpenLANE automated workflow. The proposed final design is compatible with 32-bit microcontrollers, has a total area of 104,585 µm2, and operates at a maximum clock frequency of 97.9 MHz. Several optimization configurations were tested and analyzed during the synthesis phase to enhance the performance of the final design.
