A high-fidelity energy-efficiency prediction model is first established by combining the Whale Optimization Algorithm (WOA) with a Backpropagation Neural Network (BP), enabling accurate estimation of milling power and specific cutting energy based on spindle speed, feed rate, depth of cut, and milling width. On this basis, a multi-objective optimization scheme is developed using the second-generation Non-dominated Sorting Genetic Algorithm (NSGA-II), targeting the simultaneous minimization of the two energy indicators. The entropy-weighted TOPSIS method is subsequently employed to rank the Pareto-optimal solutions and determine the most favorable parameter combination. Experimental validation demonstrates that the optimized parameters result in reductions of 12.33 % in milling power and 20.01 % in specific cutting energy compared to empirical settings. The proposed method not only realizes the synergistic optimization of energy-related objectives but also demonstrates the effectiveness and robustness of WOA-BP and NSGA-II in addressing complex process optimization problems, offering a promising approach to support energy-efficient and sustainable CNC milling.</div></div>","PeriodicalId":7484,"journal":{"name":"alexandria engineering journal","volume":"128 ","pages":"Pages 786-795"},"PeriodicalIF":6.8,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing works, while addressing aspects such as encryption, authentication, and intrusion detection, exhibit limitations including high computational overhead, centralized vulnerabilities, limited adaptability, and scalability challenges.

A novel authentication mechanism enables fine-grained access control and device verification. Real-time intrusion detection is achieved through Cascaded Deep Learning CasDL), offering high accuracy against evolving threats. Additionally, an incentive mechanism-based blockchain supports secure data usage, traceability, and regulatory compliance by maintaining an immutable ledger of access and usage activities. The model combines cryptography, authentication, threat detection, and blockchain-enabled auditability into a scalable and adaptable system with flexible key lengths and encryption rounds.

The proposed design represents the first masked nibble-sized finite field S-box, incorporating an optimized affine transformation that minimizes the XOR gate count for a compact design and low Transparency Order (TO), thereby enhancing resistance to PAA. The masking technique employed strengthens security by randomizing power consumption patterns of the non-linear inverse operations.

Further, it reduces area overhead by 40 % compared to round-based lightweight cipher architectures employing multi-share Threshold Implementation (TI) techniques.
