TTP Unveils New Product to Counter the Quantum Computing Threat
Singapore, 23 October 2025 – Today, The Thought Projects (TTP) unveiled a new product called DenseKey Transceiver to counter the quantum computing threat. The rapidly advancing quantum computing technology poses a serious threat to data security. Malicious actors can harvest encrypted data now and decrypt it later once a large-scale quantum computer becomes available. We need to begin replacing quantum-vulnerable algorithms with quantum-safe alternatives.
For organizations handling highly-sensitive data or requiring long-term data protection, a defense-in-depth strategy is recommended.
First layer of defense – Post-Quantum Cryptography (PQC)
PQC should be used for key exchange. However, the security of PQC is not mathematically proven. Future breakthroughs in cryptanalytic techniques could break or weaken current PQC schemes.
Second layer of defense – Quantum Key Distribution (QKD)
QKD can be used in combination with PQC. By combining PQC and QKD keys into a single hybrid key, the overall system is secure as long as at least one of them remains secure. Although QKD has been theoretically proven to be secure, and QKD products may undergo rigorous security evaluation and testing, practical QKD products may still contain undiscovered side-channels that could potentially expose them to zero-day attacks.
Third layer of defense – Ciphertext Masking
As an additional safeguard, ciphertext masking can be applied. The method ensures an attacker cannot obtain a usable copy of the ciphertext from the data channel. Without a usable copy of the ciphertext, even if the attacker compromises both PQC and QKD keys, there would be nothing for the attacker to decrypt.
The DenseKey Transceiver implements quantum noise ciphertext masking that prevents any attacker from harvesting the ciphertext from the data channel. Quantum noise is a fundamental property of nature. It is truly random and cannot be predicted or manipulated by anyone. This product supports a data rate of 1.25 Gbps. The transmission distance has been tested up to 200 km. It is plug-and-play and compatible with other cryptographic schemes, including AES, PQC and QKD.

TTP Launches Security Evaluation and Testing Services for Commercial QKD Products
Singapore, 21 October 2025 – The Thought Projects (TTP), a Singapore-based innovation leader in the space of future-proof data security, today announced the launch of its Quantum Key Distribution (QKD) Security Evaluation and Testing Services. Building on its completion of white-box testing on multiple commercial QKD products, TTP now offers organizations a comprehensive suite of QKD security evaluation and testing services — spanning white-box, grey-box, and black-box approaches — to validate and strengthen the security of commercial QKD products.
QKD is widely regarded as a cornerstone of future-proof data networks, offering provably secure key exchange to defend against the emerging quantum computing threat. However, real-world implementations often introduce side-channel vulnerabilities that could undermine security. Independent security evaluation and testing is therefore crucial to ensure protection against side-channel attacks and build trust among end-users.
“Having completed white box testing of multiple commercial QKD products, we have unique insights into both the strengths and weaknesses of today’s commercial QKD implementations,” said Dr. LIM Han Chuen, co-founder of TTP. “Thanks to our white-box testing experience, our grey- and black-box evaluation methodologies are rigorous and comprehensive, delivering results that clients can trust. By offering white-box, grey-box, and black-box testing, we give our clients the flexibility to choose the type of evaluation that best matches their security needs.”
As an independent third-party with no connection to any QKD manufacturer, TTP is unbiased in its security evaluation and testing work. Beyond testing and identifying risks, TTP also provides actionable recommendations that help clients enhance their security and improve resilience. The combination of real-world experience and deep technical expertise has established TTP as a trusted partner for early adopters of QKD.
About TTP
The Thought Projects (TTP) is a Singapore-based data security technology company with deep expertise in future-proof data security, specializing in the security evaluation and vulnerability testing of commercial quantum key distribution (QKD) systems. TTP is also actively developing data protection solutions. TTP’s mission is to ensure future-proof data security in the post-quantum era.
From Quantum-Safe to Future-Proof
Revolutionizing Data Security with Quantum Technology
Quantum-Safe Data Protection
QUANTUM COMPUTING THREAT
Large-scale quantum computers would be capable of breaking most of the asymmetric cryptographic schemes in use today. This poses a serious threat to the security of our sensitive data.
HARVEST NOW, DECRYPT LATER
Attackers can harvest encrypted data transmitted over public networks today and decrypt it later using quantum computers, once they become available.
POST-QUANTUM CRYPTOGRAPHY
Post-quantum cryptography (PQC) consists of algorithms that are believed to be resistant against quantum computer attacks, and several have already been standardized. Organizations should begin migrating to PQC as soon as possible.
QUANTUM KEY DISTRIBUTION
Quantum key distribution (QKD) exploits quantum physics to distribute cryptographic keys with theoretically perfect security. Rigorous security evaluation and testing are essential to ensure the absence of side-channel vulnerabilities in QKD systems.
HYBRID SCHEME
The most effective strategy today is to combine PQC and QKD into a hybrid scheme for defense-in-depth. As long as one of them remains secure, sensitive information is protected. The likelihood of an attacker compromising both is extremely low.
SUPPORT
We do not sell QKD or PQC products. As an independent third-party, we are committed to providing unbiased guidance to our clients in selecting the most suitable quantum-safe solutions and in ensuring the security of their sensitive data.
