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.

PalmPay Strengthens Data Protection Culture with Employee Privacy Workshop and Privacy Champions Programme

PalmPay has reinforced its commitment to responsible data governance and customer information protection through a specialised two-day data protection workshop for employees and the launch of its internal Privacy Champions Programme, an initiative designed to strengthen awareness, accountability, and responsible data handling across the organisation.

The initiative comes at a time when data protection is increasingly critical following recent reports of recorded 281,500 compromised user accounts in the first quarter of 2026, ranking 34th among the world’s most breached countries, according to a new quarterly data breach analysis by cybersecurity firm, Surfshark.
Facilitated by the Nigeria Data Protection Commission (NDPC) and leading Data Protection Compliance Organisation (DPCO) TechHive Advisory, the two-day workshop equipped employees with practical knowledge on privacy governance and data protection obligations, incident awareness, and the role each employee plays in protecting personal data.
The initiative forms part of PalmPay’s ongoing efforts to advance compliance with the Nigeria Data Protection Act (NDPA) 2023. It also reflects the company’s continued investment in safeguarding customer information and fostering a culture where privacy remains everyone’s responsibility.
The Privacy Champions Programme establishes a network of employee representatives across business functions who will support awareness, promote best practices and help strengthen the organisation’s privacy culture. By integrating privacy considerations into day-to–day activities the initiative aims to further enhance accountability and reinforces customer trust.
Speaking on the initiative, Managing Director of PalmPay, Chika Nwosu, stated: “At PalmPay, protecting customer information is fundamental to maintaining the trust our customers place in us everyday, and remains central to our operations. Statistically, 10 out of 100 Nigerians have been affected by data breaches.
Hence, we have a greater responsibility to ensure that personal information is collected, processed, stored, and protected responsibly. This specialised training reflects our continued investment in strengthening internal awareness and ensuring our teams remain equipped to uphold the highest standards of data privacy and protection.”
