All protocols currently used for secure communications are threatened by quantum computers. According to experts at NIST(National Institute of Standards and Technology) in the near future, current asymmetric key encryption techniques will be completely breached by quantum computers. But not only data in transit, but also data at rest such as, e.g. your most sensitive data stored in large databases.
These threats force governments, individuals and businesses to explore more secure ways of handling and storing information. The best way to protect our files is to use post-quantum cryptography (PQC); new encryption algorithms, based on mathematical problems, which would be an obstacle for both conventional and quantum computers.
Along these lines, NIST has standardised three post-quantum encryption methods. One of them, CRYSTALS-Kyber, is the one used in Quantum Drop Beta. The goal is for users to store and share their sensitive information 100% securely now and in the future.
Why is post-quantum cryptography so necessary?
Quantum computers can make calculations using the rules of quantum physics. Instead of using traditional bits like classical computers, which can be 0 or 1, they use quantum bits or qubits, which can be 0, 1, or both at the same time. This ability to be in multiple states simultaneously is called quantum superposition. This allows complex problems to be solved in a matter of seconds, calculations that a current computer would take years to perform, and it is precisely this capability that puts information security most at risk. The use of post-quantum cryptography is the best way to protect against these threats.

What is TU Quantum Drop Beta and what is it for?
Along these lines, the TU brand has developed a new service that is ahead of quantum technology: Quantum Drop Beta. This solution allows you to encrypt, decrypt, store and share files with complete security and confidentiality. You will havetotal control of information as encryption occurs locally, i.e. nothing leaves of the servers without being encrypted (zero-knowledge proof). This concept ensures data checks without the server having access to the sensitive information itself. This is particularly useful for security and privacy in transaction services and data storage.
Whit Quantum Drop Beta, your files are stored in the cloud using PQC communications algorithms and are shared only with whomever you want using tamper-proof encryption keys. Now you can try the Beta version completely free of charge. To do this, you just have to sign up with your Google account.
Quantum Drop Beta is one more of TU projects with which we want to anticipate the risk posed by the arrival of quantum computers. At TU we want to be a global benchmark in digital innovation for individuals and companies looking for technological solutions that add value and improve their quality of life and connection with the world. Therefore, we have developed products such as Latch, the security switch for digital life, Metashield, the metadata manager to control the documentary information of companies and VerifAI, the tool that identifies whether the files analysed are created or manipulated by artificial intelligence.
