Crunchfish released today an upgraded version of the Digital Cash SDK which enables privacy by design for offline payments in CBDC and commercial payment systems. In parallel, Crunchfish has applied for a patent for its innovative privacy feature, balancing privacy with regulatory requirements for transactional traceability. Privacy is deemed a key feature in CBDC systems to be adopted by the public.

Privacy is a key feature for CBDC systems to be adopted by the public. Several ongoing CBDC initiatives across the world place privacy very high on the agenda, e.g. the Digital Euro project and the Brazilian CBDC pilot Drex. Crunchfish’s innovative privacy by design feature enables payers to make completely private payments for amounts below defined thresholds. A consumer who pays a merchant below a defined threshold amount would not disclose any personal information, neither to the merchant nor the intermediary or Central Bank. With Crunchfish Digital Cash the payer enjoys a similar level of privacy as paying with physical cash.

Highlights in the upgraded Digital Cash SDK version 2.5 include:

• Privacy by design – Balancing privacy with regulatory transactional traceability requirements
• Secure time – Increasing security in the payment timestamp and preventing users from changing the device time to use expired or not yet valid certificates
• Improved certificate management 
• Enhanced fraud detection capability and fraud management
• Increased security
• Improved integration support – enriched documentation and new backend components

“We have released many new features based on requirements from CBDC and other offline projects. Our development team has been working hard to meet the requirements from the market and the pilots we have been running. I’m really proud that we now can offer privacy by design as we know this is a key requirement in many CBDC projects.” says Magnus Lageson, CPO at Crunchfish Digital Cash.

The upgraded Digital Cash version 2.5 will be made available for all customers through the Crunchfish Developer portal. 

In parallel with making this upgrade Digital Cash version available, Crunchfish applied yesterday for a Swedish patent for balancing regulatory requirements for transactional traceability with true privacy through encryption of transactional information for amounts below defined thresholds, defined by the issuer and the regulator, using wallet keys. The patent if granted is valid for 20 years until April 2044.

As further background on privacy Lipis Advisors in collaboration with Crunchfish released in May 2023 this whitepaper on privacy considerations in offline payments systems.

Crunchfish introduces App-integrated Card Emulation (ACE) offering the security of Mobile Card Emulation (MCE) without sacrificing the scalability provided by tokenized card payments with Host-based Card Emulation (HCE).

Card payments is a common payment method that banks offer their customers. To enable card payments from a mobile device in a secure way that is scalable to all customers have proven to be difficult. It is either limited to users of select mobile devices or operators (MCE) or alternatively only available for e-commerce or terminal purchases that requires online clearing. The ground-breaking mobile technology that Crunchfish has developed for offline payments is also applicable for mobile card payments.

This whitepaper by Crunchfish introduces App-integrated Card Emulation (ACE) as a novel way of card emulation. The initial section relates ACE to other ways of Card Emulation (CE) – Mobile Card Emulation (MCE) using a hardware-based Secure Element (SE) and Host-based Card Emulation (HCE) with tokenized payment credentials. The second section discusses Implementation Architectures using hardware-based as well as software-based protection. The third section discusses Data Integrity during runtime operation, for stored data at rest and for data in transit. The conclusion includes a comparison table of MCE, HCE and ACE that summarizes the points raised in the three sections of this whitepaper.

Crunchfish Digital Cash AB (“Crunchfish”) has received an International Preliminary Report on Patentability (IPRP) in Chapter II of the Patent Cooperation Treaty (PCT) for a key Digital Cash patent application PCT/SE2023/050294 with a focus on making Digital Cash quantum-safe, indicating that all claims 1 – 45 are deemed patentable. This patent makes Crunchfish Digital Cash future-proof and secured for attacks by quantum computing and extends Crunchfish extensive patent portfolio within the Digital Cash business area.

Crunchfish has applied for a patent that makes Digital Cash resistant to attacks by quantum computing, keeping payment information secure even after large-scale quantum computers has been built. The advent of large-scale quantum computing offers great promise to science and society but brings also significant threats to the global information infrastructure. Public-key Infrastructure, widely used on the internet today, relies upon cryptography that is believed to be secure given the computational power currently available. However, popular cryptographic schemes, including RSA and Elliptic Curve Cryptography, will be easily broken by a quantum computer. This will rapidly accelerate the obsolescence of our currently deployed security systems and will have dramatic impacts on any industry, including payments, where information needs to be kept secure.

The innovation is based on combining two different data integrity schemes and offers a new paradigm for offline payments that addresses the challenges which can be expected in the era of quantum computing. A two-step process is applied. Payments are first negotiated offline by short-range data communication using a quantum-secure cryptographic key as a shared secret. Subsequently, payment settlement by broadband data communication is secured by signing the settlement request with another quantum secure cryptographic key.

With quantum computing, all information that is transmitted on public channels is vulnerable to eavesdropping. Encrypted data can also be stored for later decryption once quantum computing becomes available. Bitcoin is one example where previously made transactions are accessible by anyone and puts a substantial amount of Bitcoin at risk. Even if large-scale quantum computers are still a few years into the future, preparations must be made now, as the timing when technical innovation leapfrogs is hard to predict.

“We are extremely happy that yet another innovation has been deemed patentable. It strengthens Crunchfish leadership in offline payments by making Digital Cash safe for quantum computing attacks. It solves a key problem that must be addressed in the advent of quantum computing”, says Joachim Samuelsson, CEO of Crunchfish.

The patent has priority from a Swedish patent application filed in March 2022. The next step is to enter the phase of nationalization by September 2024 when Crunchfish must decide which markets to protect this important innovation. A patent would be valid until March 2042, 20 years from the original filing date.

Crunchfish Digital Cash (“Crunchfish”) has received a positive International Search Report in the international patenting process for its strategically important Trusted Application Protocol (TAP) patent application. Crunchfish’s communication security protocol for mobile applications is based on TAP as it provides end-to-end integrity if internet access is available and enables communication over alternative networks if internet is not available.

Digital payments are not as robust as required given its critical role as a public good in the modern society. This is also true for digital applications in general. Typically implemented using a client server network model, the TAP enables digital service without internet access. Crunchfish’s innovative product Digital Cash telecom is an example of the use of TAP when internet access is not available. This will be piloted for the Digital Rupee, the Central Bank Digital Currency (CBDC) in India. When the internet TCP/IP communication is available the TAP enables end-to-end integrity for client server communications.

The International Search Report (ISR) is the first feedback round in the international PCT patenting process. This has now been issued for Crunchfish’s strategically important TAP patent application with international patent application number PCT/IB2024/051131. The PCT-process and its milestones was described in more detail in the Crunchfish press release from April 2021 when Crunchfish received the ISR for its initial patent application within Digital Cash. 

“The Trusted Application Protocol is a strategically important innovation for Crunchfish as our communication security protocol for mobile applications is based on TAP. Whereas the internet TCP/IP protocol provides survivability in the face of failures between networks, Crunchfish’s TAP provides integrity and robustness for communications between client applications and host servers as well as between applications in proximity”, says Crunchfish CEO and inventor Joachim Samuelsson.
