In an age where data flows in real time and digital threats evolve just as swiftly, traditional cybersecurity methods often fall short. As the Internet of Things (IoT) and time-series data applications continue to grow, impacting critical infrastructure, energy systems, and smart cities, the need for faster, scalable, and secure encryption has become urgent. Innovations in encryption protocols, particularly for high-velocity data, are becoming essential components of digital defense strategies. Emerging from this dynamic intersection of speed and security is a new approach to encryption that transforms what is possible in real-time data protection.
An innovation titled Fast Encryption Cipher Block Chaining Mode (FCBC Mode) is offering just that speed without compromising security. The concept, developed and published by cybersecurity innovator Binoy Kurikaparambil Revi, marks a significant advancement in data encryption. Unlike traditional Cipher Block Chaining (CBC) modes, the Fast Cipher Block Chaining (FCBC) method, which is derived from CBC, reduces the encryption time per block by 15% to 25%. This improvement is particularly beneficial for environments that are sensitive to latency. “Speed in encryption doesn’t just reduce lag; it increases the practicality of deploying robust security across IoT and other data-intense ecosystems,” the author notes in his published paper.
Recognition for this advancement came in the form of a prestigious accolade—the 2025 Titan Business Awards Gold, awarded under the Information Technology – Cybersecurity category. The judging panel praised the innovation as “the cream of the crop across the world,” citing its strategic brilliance and real-world relevance. Unlike proprietary solutions that limit accessibility, this protocol has been released as an open-source resource. This initiative fosters widespread adoption and encourages continuous improvement within the global cybersecurity community.
The application of FCBC Mode to secure critical time-series data has many operational benefits. By providing a faster encryption option for systems relying on constant data streams, such as industrial IoT setups, encrypting the medical data streams like patient continuous monitoring data, FCBC provides significant improvements in processing time, system responsiveness, and security performance. In sectors like power utilities, where Phasor Measurement Units transmit sensitive readings from secured locations, FCBC can play a critical role in securing data transmission without compromising speed or precision.
One of the unique aspects of the FCBC protocol is its built-in flexibility. The structure includes an Operation Flag field, enabling application-specific metadata to be securely embedded within each data packet. This feature addresses a longstanding challenge in adapting rigid encryption structures for diverse use cases, from healthcare devices to smart manufacturing. “We required a framework that not only secures data but also adapts to the specific security requirements of each industry.” Revi explains.
One major hurdle was data fragmentation across outdated or legacy encryption systems. By focusing on modular design and ensuring that the protocol could integrate domain-specific information seamlessly, the innovation overcame these long-standing barriers. The result is a lightweight, adaptable, and future-ready encryption scheme suited for the evolving needs of modern computing.
His thoughts on the future of encryption are as bold as the innovation itself. With the rise of quantum computing, conventional assumptions about cryptographic security are rapidly being dismantled. The once-reassuring idea that encryption could remain impenetrable for lifetimes is no longer guaranteed. “Cybersecurity must evolve as fast as computational power does. We can’t rely on outdated principles in a quantum-enabled world,” Revi emphasizes.
This perspective is rooted in forward-thinking design. As cloud platforms and edge computing architectures grow increasingly powerful, encryption protocols must match their speed and adaptability. The FCBC Mode is more than a technical upgrade, it represents a philosophy of anticipatory security design, where future threats are addressed not just with stronger locks, but with faster, smarter ones.
By publishing the protocol and making it accessible, his innovation not only improves technical performance but also contributes meaningfully to the broader cyber-security discourse. It invites collaboration, encourages transparency, and provides a foundation for future research and development, especially in areas where streaming data is both a necessity and vulnerability.
As industries race to keep up with the demands of data-intensive environments, efforts like FCBC Mode are critical. They do not merely follow the trends, they shape the path forward.
