“…Many present-day widely used cryptosystems could collapse (Alyami et al 2022). This makes a transition to new systems necessary that has a far greater scope and implications as classical security transitions (Joseph et al 2022).…”

“…If the migration to quantum computer safe cryptography takes too long, data that has to be kept safe for a certain time might be left unprotected when quantum computers are available (Mosca 2018). However, quantum computers are not only relevant in the future, but also already pose an active threat (Joseph et al 2022). Attacks can be realized by storing encrypted data now and decoding it as soon as quantum computers become available, also called a store-now-decrypt-later attack (Cesare 2015;Joseph et al 2022).…”

Because of this, appropriate quantum-secure cryptography measures should be used sooner rather than later and strategic planning by companies should have already begun if data must be protected for more than five years or is used in the long-term planning of projects.…”

“…Because of this, appropriate quantum-secure cryptography measures should be used sooner rather than later and strategic planning by companies should have already begun if data must be protected for more than five years or is used in the long-term planning of projects. Because of this, most companies can already be considered late (Joseph et al 2022).…”

“…While quantum cryptography works with quantum phenomena and thus is suited for quantum computers, post-quantum cryptography aims to encrypt with algorithms on classical computers in a way it can't be decrypted by quantum computers. Especially post-quantum cryptography is seen as suitable for companies because it is easier to establish in a conventional infrastructure (Joseph et al 2022). The development of these measures and their international standardization is underway (National Institute of Standards and Technology 2022) and has already produced four algorithms that are planned to be included in future standards (NIST 2022).…”

Quantum computers are currently in development. As soon as they are available for widespread use, they can offer great benefits for companies. However, they can also pose dangers to information security. Because of this, protection measures are needed. To gain an insight into the outlook and knowledge of companies on quantum computing and their internal decision processes when establishing new technologies, qualitative interviews were conducted. Because not all companies know about quantum computing, the questions were designed without necessary previous knowledge in mind. Additionally, an employee of the German Federal Office for Information Security (BSI) was asked for their opinions. Many of the interviewed companies were not well informed about quantum computing and some lacked preparation of their general IT security. However, they had ideas how they could utilize such a much more powerful computer in the future. To gauge how quantum-secure measures could be implemented among companies, the companies were asked about their decision criteria when deciding on implementing a new technology. Their answers often included price and distribution, functions of the technology and external influences like other companies or guidelines from the government. To support the transition to quantum computer-safe cryptography in companies, different areas of action are examined. Supporting the availability of relevant use cases, market incubation and standards, collaboration between companies and education among them can help in pushing the spread of post-quantum security in companies in the future.

Optical grating devices based on micro/nanostructured functional surfaces are widely employed to precisely manipulate light propagation, which is significant for information technologies, optical data storage, and light sensors. However, the parameters of rigid periodic structures are difficult to tune after manufacturing, which seriously limits their capacity for in situ light manipulation. Here, a novel anti‐eavesdropping, anti‐damage, and anti‐tamper dynamic optical encryption strategy are reported via tunable mechanical composite wrinkle micrograting encryption systems (MCWGES). By mechanically composing multiple in‐situ tunable ordered wrinkle gratings, the dynamic keys with large space capacity are generated to obtain encrypted diffraction patterns, which can provide a higher level of security for the encrypted systems. Furthermore, a multiple grating cone diffraction model is proposed to reveal the dynamic optical encryption principle of MCWGES. Optical encryption communication using dynamic keys has the effect of preventing eavesdropping, damage, and tampering. This dynamic encryption method based on optical manipulation of wrinkle grating demonstrates the potential applications of micro/nanostructured functional surfaces in the field of information security.
