The Power of Chaos: A Robust and Low-Cost Cryptosystem for the Post-Quantum Era

Fast algorithms on quantum computers could easily break many widely used cryptosystems, necessitating more innovative solutions for digital security.

In a recent study, a team of scientists designed a stream cipher consisting of three cryptographic primitives based on independent mathematical models of chaos.
The resulting cryptographic approach is robust to attacks from large-scale quantum computers and can be implemented on low-cost computers, paving the way to secure digital communications in the post-quantum era.
While for most of us cryptographic systems are things that just run “under the hood,” they are an essential element in the world of digital communications.
However, the upcoming rise of quantum computers could shake the field of cryptography to its core. Fast algorithms running on these machines could break some of the most widely used cryptosystems, rendering them vulnerable.
Well aware of this looming threat, cryptography researchers worldwide are working on novel encryption methods that can withstand attacks from quantum computers.
Chaos theory is actively being studied as a basis for post-quantum era cryptosystems. In mathematics, chaos is a property of certain dynamic systems that makes them extremely sensitive to initial conditions.
While technically deterministic (non-random), these systems evolve in such complex ways that predicting their long-term state with incomplete information is practically impossible, since even small rounding errors in the initial conditions yield diverging results.
This unique characteristic of chaotic systems can be leveraged to produce highly secure cryptographic systems, as a team of researchers from Ritsumeikan University, Japan, showed in a recent study published in IEEE Transactions on Circuits and Systems I.
Led by Professor Takaya Miyano, the team developed an unprecedented stream cipher consisting of three cryptographic primitives based on independent mathematical models of chaos.
The first primitive is a pseudorandom number generator based on the augmented Lorenz (AL) map. The pseudorandom numbers produced using this approach are used to create key streams for encrypting/decrypting messages, which take the stage in the second and perhaps most remarkable primitive—an innovative method for secret-key exchange.
This novel strategy for exchanging secret keys specifying the AL map is based on the synchronization of two chaotic Lorenz oscillators, which can be independently and randomly initialized by the two communicating users, without either of them knowing the state of the other’s oscillator.
To conceal the internal states of these oscillators, the communicating users (the sender and the receiver) mask the value of one of the variables of their oscillator by multiplying it with a locally generated random number.
The masked value of the sender is then sent to receiver and vice-versa. After a short time, when these back-and-forth exchanges cause both oscillators to sync up almost perfectly to the same state in spite of the randomization of the variables, the users can mask and exchange secret keys and then locally unmask them with simple calculations.
Finally, the third primitive is a hash function based on the logistic map (a chaotic equation of motion), which allows the sender to send a hash value and, in turn, allows the receiver to ensure that the received secret key is correct, i.e., the chaotic oscillators were synchronized properly.
The researchers showed that a stream cipher assembled using these three primitives is extremely secure and resistant to statistical attacks and eavesdropping since it is mathematically impossible to synchronize their own oscillator to either the sender’s or the receiver’s ones.
This is an unprecedented achievement, as Prof. Miyano states: “Most chaos-based cryptosystems can be broken by attacks using classical computers within a practically short time. In contrast, our methods, especially the one for secret-key exchange, appear to be robust against such attacks and, more importantly, even hard to break using quantum computers.”
In addition to its security, the proposed key exchange method is applicable to existing block ciphers, such as the widely used Advanced Encryption Standard (AES). Moreover, the researchers could implement their chaos-based stream cipher on the Raspberry Pi 4, a small-scale computer, using Python 3.8.
They even used it to securely transmit a famous painting by Johannes Vermeer between Kusatsu and Sendai, two places in Japan 600 km apart. “The implementation and running costs of our cryptosystem are remarkably low compared with those of quantum cryptography,” highlights Prof. Miyano, “Our work thus provides a cryptographic approach that guarantees the privacy of daily communications between people all over the world in the post-quantum era.”
With such power of chaos-based cryptography, we may not have much to worry about the dark sides of quantum computing.

Woherem Proposes Pragmatic Roadmap to End Terrorism and Banditry in Nigeria

Dr. Evans Woherem, an award-winning African technology researcher, analyst, and writer, has proposed a comprehensive and implementable strategy to end terrorism, banditry, and criminal violence in Nigeria, warning that the country’s prolonged insecurity has reached a critical point that demands urgent, coordinated action.

Titled “A Comprehensive Strategy for Ending Terrorism, Banditry, and Criminal Violence in Nigeria: A Pragmatic, Multi-Layered, and Implementable Framework,” the paper presents a holistic roadmap designed to reverse more than a decade of escalating violence that has claimed thousands of lives, displaced communities, weakened local economies, and eroded public trust in governance.
According to him, insecurity has become deeply entrenched in everyday life across the country. “Terrorism, banditry, and criminal violence have become so commonplace that they now dominate daily conversations among Nigerians,” Dr. Woherem noted, adding that while the crisis is most acute in the North-East, North-West, and North-Central regions, “its effects are now being felt even in the southern parts of the country.”
Citing the 2025 Global Terrorism Index, which ranks Nigeria sixth globally in terms of terrorism impact, Dr. Woherem described the ranking as “a sobering statistical confirmation that terrorism still weighs heavily on the Nigerian state.”
The paper traces the roots of the crisis to the emergence of Boko Haram in 2009 and the subsequent rise of splinter groups such as ISWAP. It recalls high-profile incidents including the 2014 abduction of schoolgirls in Chibok, the Dapchi and Kankara kidnappings, and a series of mass abductions and attacks on schools and places of worship recorded in 2025.
Dr. Woherem observed that banditry, largely driven by ransom payments, “has spread across the entire nation, creating fear, weakening productivity, and pushing millions of households deeper into poverty.”
While acknowledging the role of military action, the author cautioned against relying on force alone. “Nigeria cannot defeat insurgency and violent crime through arms and ammunition alone,” he said. “Any sustainable solution must confront the internal conditions that allow insecurity to thrive.”
Among the key drivers identified in the paper by Dr. Woherem, are porous borders, arms proliferation, youth unemployment, economic stagnation, and persistent conflicts over land and resources, challenges Dr. Woherem stressed can be addressed through “a deliberate, intelligence-led, and whole-of-society approach.”
At the heart of the proposed framework, Woherem noted, is a call for intelligence-driven security operations, including the establishment of a National Counter-Insurgency and Intelligence Fusion Centre. “Security operations must be guided by accurate, actionable intelligence rather than fear-led mass actions that often harm civilians and undermine public trust,” he stated.
The paper also advocates comprehensive policing reforms, including the creation of constitutionally backed state police systems supported by a more specialized federal police structure. “Nigeria’s over-centralised policing model is structurally incapable of effectively addressing widespread criminality across such a vast and diverse country.”
Recognising the realities at the grassroots, Woherem calls for the formal regulation of community-based security groups, and noted that “ignoring vigilante groups is dangerous, and banning them outright is unrealistic,” but stressed that their roles must be clearly defined, regulated, and subject to strict oversight.
On border security, particularly in the Lake Chad Basin, the author warned that instability in neighbouring countries continues to fuel Nigeria’s insecurity. “No permanent solution is possible without deep regional cooperation,” he said, advocating an Integrated Border Management system supported by joint operations with neighbouring states.
The paper places strong emphasis on prevention through economic inclusion, youth employment, and skills development. “Jobs and income remain the most powerful tools for preventing recruitment into violent groups,” Dr. Woherem asserted, adding that immediate livelihood opportunities significantly weaken the appeal of extremist narratives.
He also called for structured deradicalisation and reintegration programmes, noting that “a humane, community-accepted process is essential for breaking cycles of violence and preventing relapse into extremism.”
Dr. Woherem further emphasised the need for governance reforms and accountability in the security sector. “Without transparency, oversight, and institutional integrity, even the best security strategies will fail,” he warned.
The white paper outlines a phased implementation plan from 2025 to 2030, beginning with intelligence fusion, pilot state police initiatives, community security registration, drone surveillance, and financial crackdowns on terror networks, before expanding into nationwide reforms and long-term consolidation.
Concluding, Dr. Woherem expressed cautious optimism about Nigeria’s future. “Nigeria can overcome this prolonged phase of insecurity,” he said, “but only through political will, coordinated institutions, and the active participation of society.”
He added that the proposed framework offers “a realistic pathway to restoring security, rebuilding public trust, and unlocking Nigeria’s vast human and economic potential.”

REDAN Seals Landmark MoU, Validates Sytemap’s Real Estate Infrastructure

In a market where less than 3% of land is formally registered and property fraud remains systemic, infrastructure, not apps, is becoming the defining battleground for real estate innovation.

L-R: Ndifreke Ikokpu, COO, Sytemap, HRM Oba Akintoye Adeoye, President REDAN & Cholatte Odunlade-Akeji, Director, RightHome
That reality came into sharp focus on December 18, 2025, as the Real Estate Developers Association of Nigeria (REDAN) signed a Memorandum of Understanding (MoU) with Sytemap Technologies Limited, signaling a major industry endorsement of Sytemap’s land and real estate transaction infrastructure.
The partnership centers on RightHOME, a jointly developed digital real estate platform powered by Sytemap’s secure cloud infrastructure, mapping systems, transaction monitoring, and fraud-prevention architecture, with REDAN driving ecosystem adoption through its nationwide developer network.
Nigeria’s real estate sector processes transactions worth trillions of naira annually, yet remains heavily manual, fragmented, and vulnerable to disputes. Industry data suggests unresolved title issues alone lock up ₦36 trillion in dead capital, limiting access to finance and slowing development.
“This MoU represents a shift from fragmented digitization to coordinated infrastructure,” said Nnamdi Uba, CEO at Sytemap. “When the industry body itself aligns around shared standards, verification, and technology, innovation can finally scale responsibly.”
Under the agreement:
· REDAN will onboard registered developers and promote adoption of the platform as a trusted digital channel.
· Sytemap will deliver secure hosting, real-time monitoring, escrow-aligned transaction workflows, and compliance with Nigeria’s data protection regulations.
· Joint standards will be developed for digital verification, transparency, and asset mapping.
From a technology perspective, the partnership reflects a growing consensus that solving African real estate challenges requires deep infrastructure, not surface-level marketplaces. Fraud detection, uptime reliability, auditability, and regulatory alignment, areas often overlooked in proptech, are central to Sytemap’s approach.
HRM Oba Akintoye Adeoye, representing REDAN noted, “This collaboration allows developers to operate in a system where trust is embedded, not assumed. That is critical for long-term growth.”
For the broader tech ecosystem, the MoU stands out as a rare example of industry-led validation, where a national association formally aligns with a technology provider to modernize an entire sector.
Ndifreke Ikokpu, COO at Sytemap signed on behalf of Sytemap while Cholatte Odunlade – Akeji, CEO of RightHome signed on behalf of the Special Purpose Vehicle.
As pressure mounts to unlock housing finance, attract institutional capital, and reduce transaction risk, the REDAN–Sytemap partnership positions digital land infrastructure not as an optional upgrade, but as a foundational requirement for the future of real estate in Nigeria.
