As a result, security is a critical aspect of NoCs, and it is essential to protect them from various security threats such as information leakage, denial of service attacks, and unauthorized access. The communication over NoCs carries sensitive and confidential information, which needs to be protected from unauthorized access, interception, or tampering. A Hybrid Secure technique is proposed in this research paper to protect the data during NoC transmission. The Noekeon and RSA algorithms are combined to create the hybrid secure algorithm for NoC architecture. The Noekeon algorithm provides a high level of security, efficiency, flexibility, and resistance to side-channel attacks, making it an ideal choice for securing communication in NoC and other applications. The RSA encryption algorithm is modified to minimize the number of calculations. The proposed hybrid secure algorithm is tested on 4 × 4 2D mesh NoC architecture.

Due to the growing significance of wireless communication in recent years, very inventive research has been conducted.

The activation of every comparison circuit on every clock cycle is primarily responsible for the significant power dissipation, which leads to increased recharge activity and multiple transition occurrences in the ML. In order to overcome this issue, a novel Common Match Line Scheme (CMS) with a Pull Up/Pull Down (PUPD) Circuit is proposed. The new design of the CMS CAM architecture leverages by utilizing these technique, the mismatched tagline entries are kept in the pre-discharged phases, and only the matching tagline entry gets charged. Consequently, these approaches effectively reduce pre-charge activity and mitigate evaluate-power, thereby alleviating power dissipation concerns associated with CAM 13–45% and reducing delay 3–16% while comparing to the existing architectures without significant impact on the performance of the processor.

Increasing the transconductance of the auxiliary amplifier mitigates the distortion. Adaptive bias offers the possibility to control the output current characteristic of the auxiliary amplifier. This means that adaptive bias linearises and mitigates the need for an oversized auxiliary amplifier.
