Crunchfish makes Digital Cash quantum safe

2022-04-01|

Crunchfish has applied for a patent that makes Digital Cash resistant to attacks by classical and quantum computers, keeping payment information secure even after large-scale quantum computers has been built. The present invention offers a new paradigm for offline payments that addresses the challenges which can be expected in the era of quantum computing.

The advent of large-scale quantum computing offers great promise to science and society, but brings with it a significant threat to our 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 available now and in the medium term. However, popular cryptographic schemes based on these hard problems, 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.

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. Quantum computing is still a few years into the future. However, the timing when technical innovation leapfrogs are hard to predict and there are already several initiatives taken world-wide on how to address the perceived threat. For instance, The US government has issued a memorandum to define a plan by Q3 2022 to mitigate the risk.

Crunchfish has applied for a Swedish patent protecting Digital Cash by combining two different data integrity schemes. First, payments are negotiated offline by short-range data communication between payer and payee communication devices using a quantum-secure cryptographic key as a shared secret. Successfully negotiated offline payments are stored locally and securely in the devices. Subsequently, payment settlement by broadband data communication is secured by signing the settlement request with another quantum secure cryptographic key.

 

“Crunchfish demonstrates leadership in offline payments by making Digital Cash secure for quantum computing attacks. It may not be a problem that needs to be addressed today, but a patent application positions the company for the future when the problem becomes acute to solve”, says Joachim Samuelsson, CEO of Crunchfish.

Crunchfish prevents fraudulent cloning and Digital Cash double spending

2022-03-04|

Crunchfish has applied for a patent for a logical lock that protects against fraudulent use by cloning of Trusted Applications, which significantly enhances the security of any Trusted Applications running in hardware based as well as software based secure execution environments. For instance, double spending may occur if a clone of the Digital Cash offline Trusted Application is generated and continues to operate offline. This patent pending innovation prevents such double spending with Digital Cash offline.

Cloning is a technique wherein an additional identical instance of the entire host device or the trusted application running therein, depending on the security arrangement, is created. The clone may act as the original trusted application or host device. A malicious user attempting to hack the host device, or with the intent of being able to fully access all of the functionality of the host device.

Cloning a host device may give rise to critical security vulnerabilities relating to fraudulent use by cloning of a trusted application. For instance, double spending may occur if a clone of the Digital Cash offline Trusted Application is generated and continues to operate offline. Then digital currency can be consumed from the secure digital wallet of the clone. If the currently executing trusted application is subsequently switched from the clone back to the original trusted application instance, while the secure digital wallet is still offline, the original trusted application instance may once more consume the same digital currency already consumed by the cloned instance. Other related security vulnerabilities may be realized in other scenarios, for instance multi-usage of any finite resource, exploiting license timers for subscriptions or accounts or exploiting expiry timers, to name a few.

Crunchfish has applied for a Swedish patent for a method to address fraudulent use by cloning of a Trusted Applications executable in a secure execution environment of a host device by starting the Trusted Application in a locked mode. The trusted application performs a handshake procedure with a computerized backend resource to verify that a current execution state of the trusted application has not already been occupied by another instance of the trusted application. Only upon successful verification by the handshake procedure, the trusted application switches to an unlocked mode in which access to the protected functionality and data is permitted. 

This is an extremely important innovation that carries the signature of Crunchfish founder and CTO Paul Cronholm all over. It is a surprisingly simple solution with wide applicability to the security of Trusted Applications and may very well be implemented in iOS and Android. For Crunchfish it provides an important additional level of security protecting against double spending by fraudulent use of jailbroken or rooted devices”, says Joachim Samuelsson, CEO of Crunchfish.

At the moment of payment the transaction is digitally signed by the payer and transmitted locally to the payee as a message providing the payee with a digitally signed commitment, similar to a guaranteed check. If both parties are offline at the moment of payment, settlement will take place later when one of the parties has internet connection and access to the payment service’s back-end. All the transactions are logged locally by both the payer and the payee. It debits the payer’s Digital Cash offline balance and could either credit the payee’s Digital Cash offline balance or demand that the incoming payment is banked before it may be used. 

 

”It is extremely pleasing that our very first Digital Cash patent application for offline payments receives such a clean slate on patentability. This is strategically important for several reasons; the patent application has an early priority date and a very wide scope. It also raises our expectations that our many other Digital Cash patent applications may also be granted later, as they are based on the same core principles”, says Joachim Samuelsson, CEO of Crunchfish.

 

This clean report of the initial Digital Cash patent application follows the announcement of the first granted patent regarding interoperable offline payments in December 2021.

Crunchfish announces 12th Gesture Interaction patent

Augmented and Virtual Reality (AR/VR) are two important market segments for Crunchfish and entering PIN codes or passwords securely is a key problem to solve for providers of wearables and AR/VR platforms. Gesture interaction is the preferred way to enter a PIN code or password. Voice control is not an option and the use of physical buttons, if at all available, is often time consuming.

All wearables need a PIN code or password protection from unauthorized usage. As gestures are visible to people around the user, a smart mechanism protecting the PIN code or password is needed. This innovation solves it by re-arranging the letters and numbers in the virtual display. In that way, the hand movements will be different every time a PIN code or password is entered, which provides the desired protection. The patent covers both locking and unlocking of a device using gesture interaction on a scrambled virtual display.

This is Crunchfish’s 12th innovation in the area of Gesture Interaction and completes the patent portfolio as all 12 unique innovations have now been granted patents.

“This is a key patent for our gesture business that protects locking and un-locking of a wearable device in AR/VR, two of our focus markets”, says Joakim Nydemark, CEO of Crunchfish Gesture Interaction AB.
