Improving energy management is essential for sustainability since building energy use is rising.
This study is a trailblazer in using multi-criteria decision-making (MCDM) methodologies for the
real-time operational optimization of building energy systems. Data collection and pre-processing,
feature extraction, feature selection, classification, trust authentication, encryption, and decryption
are among the techniques used in this approach. Pre-processing procedures for the raw data include
feature encoding, dimension reduction, and normalization approaches. The Hybrid Grey Level Cooccurrence
Matrix Fast Fourier Transform (HGLCM-FFT) method is used for feature extraction.
Filter-based methods are used for feature selection, including IG, CS, symmetric uncertainty, and
gain ratio. The Hierarchical Gradient Boosted Isolation Forest (HGB-IF) technique is used for the
classification. Distributed Adaptive Trust-Based Authentication (DAT-BA), a security architecture
in distributed cloud environments, uses trust authentication. The Particle Swarm Optimized
Symmetrical Blowfish (PSOSB) method is used for encryption and decryption. The suggested work
is implemented using OS Python – 3.9.6; the performance of the proposed model is Attack
Detection Rate, False alarm rate, True positive rate, Network usage, CPU usage, Encryption time,
encryption time and Throughput.
