Modern wireless communication networks employ Orthogonal Frequency Division Multiplexing (OFDM), which resists multipath fading and maximises spectrum usage. Wireless networks’ private data must be protected by adequate safety techniques as data transfer becomes more important. These researches suggest adding Elliptic Curve Cryptography (ECC) to OFDM-based communication systems to improve security. Despite having smaller key sizes than other public-key cryptosystems, ECC provides significant security. This helps with restricted sources. This work builds a smart aggregation system employing OFDM and ECC to tightly close wireless channel data. We analyse the proposed system’s speed, bit errors rate (BER), and processing complexity by comparing it to non-cryptographic structures. Without affecting OFDM system performance or functioning, the incorporated ECC greatly increases information safety. This technology allows future wireless communication networks to be flexible and secure, maintaining data privacy and security.
