Cryptovision TSEv2 receives BSI certificate

Cryptovision TSEv2 receives BSI certificate

The new version 2 of Eviden’s cryptovision TSE has been certified by the German Federal Office for Information Security (BSI).

A TSE (Technical Security Equipment) is a security module for cash registers designed to prevent tax fraud. It ensures that every transaction is logged and digitally signed. Since January 1, 2020, every electronic or computerized cash register in Germany must be equipped with a TSE. From 2024, the TSE obligation will also apply to taximeters. The structure and functionality of a TSE are described in the Technical Guideline TR-03153 (Technical Security Device for Electronic Recording Systems) of the BSI.

The cryptovision TSE is an established TSE implementation from Eviden, version 2 of which has now been certified. It enables retail, catering and cab companies to record their transactions in a legally compliant manner in accordance with legal requirements and BSI specifications.

Newly published: Atos whitepaper on post-quantum cryptography

Newly published: Atos whitepaper on post-quantum cryptography

Everything you need to know as a beginner on the subject of post-quantum cryptography, explained in an understandable way on 24 pages, in a German and an English version – this is the concept of the new Atos whitepaper on the subject of post-quantum cryptography. It explains the most important algorithms in a clear manner, avoiding overly complicated mathematics. Since the year 2022 will go down in history as the one in which the standardization of post-quantum cryptography first took concrete shape, this aspect is also highlighted. And finally, the white paper addresses the challenges of the coming years. These include bringing the new methods into the existing chip architectures despite long keys and, in some cases, poorer performance. If you want to know more about these topics, you can download the Atos whitepaper on post-quantum cryptography here.

Newly published: cryptovision special issue of “The Vault” magazine

Newly published: cryptovision special issue of “The Vault” magazine

For more than a year cryptovision has been a part of the Atos family. For all those who want to know how the company has developed during this time, a special issue of the ID Security magazine “The Vault” has now been published. All articles in this magazine were written by Atos employees with cryptovision past. The special issue is available for download free of charge.

An interview with Benjamin Drisch, Senior Vice President Government ID, is not called “From hidden champion to global player” for nothing. In fact, cryptovision has developed from a small specialist into a leading international provider in the Government ID segment under the Atos umbrella. The previous Government-ID service portfolio has been expanded to include PKI solutions, a smart card operating system and hardware security modules (HSMs), while the opportunities for project implementation have increased significantly thanks to numerous new colleagues. And, of course, the globally active Atos sales force ensures that cryptovision now has much better access to its customers.

However, the cryptovision special edition of “The Vault” not only reports on cryptovision itself, but also on some exciting developments in the field of digital identities. Among other things, it is about Non-Fungible Tokens, how they are stolen and how this can be prevented – True Crime once again. Fido tokens and smartcard middleware also come up. Also worth reading is an interview with Holger Roessner, CEO of cryptovision partner Advanide.

Finally, there is something to smile about. Adam Ross, an expert in beer and digital identities, reports on an interesting point of contact between his two areas of expertise. Cryptovision says “Cheers” and hopes you enjoy reading!

US standards body NIST announces four winners in post-quantum competition

US standards body NIST announces four winners in post-quantum competition

Do you know CRYSTALS-Kyber? If not, you will certainly get to know this post-quantum encryption method soon, because it was declared one of four winners from an original 69 candidates by the US standardization authority NIST. The other three winners in this multi-year competition are the CRYSTALS-Dilithium, FALCON and SPHINCS+ post-quantum signature methods.

The background is that the asymmetric crypto methods used so far, including RSA and Diffie-Hellman, can be broken with quantum computers. Although usable quantum computers have so far only existed in science fiction, NIST wanted to respond to the looming threat at an early stage and therefore organized a competition in which methods considered to be quantum-safe were to be evaluated and some standardized at the end.

Experience shows that other standardization bodies around the world are adopting NIST’s crypto standards. The announcement of the first four winners – with a few more to follow – is therefore tantamount to a go-ahead, because after years of uncertainty, it is now foreseeable which post-quantum methods will prevail in practice. Crypto vendors around the world will now have to implement these methods, universities will have to change their curricula.

It won’t be easy for crypto enthusiasts, however, because there is higher mathematics behind post-quantum cryptography. While SPHINX+ is based on the comparatively easy-to-understand principle of one-way functions, CRYSTALS-Kyber, CRYSTALS-Dilithium and FALCON are mathematically much more sophisticated. All three belong to the so-called lattice methods and therefore require arithmetic operations in multi-hundred-dimensional lattices – not exactly what the average person learned in school.

Of course, the new post-quantum methods are now also on the roadmap at cryptovision and its parent company Atos. Cryptovision will also continue to dedicate itself to the task of explaining post-quantum cryptography clearly, be it through the popular cryptovision post-quantum whitepaper or comic-style conference presentations. The age of post-quantum cryptography can come, cryptovision and Atos are prepared.

Mindshare 2022 video: Two great days in 70 seconds

Mindshare 2022 video: Two great days in 70 seconds

Already for the tenth time cryptovision invited to Mindshare. After two years of Corona break, the two-day congress fair was awaited with particular excitement, and those who came to Gelsenkirchen were once again not disappointed.

In four tracks there were top-class presentations to follow, plus keynotes, live hacking, tutorials and panel discussions. In addition to the latest developments on eID, Internet of Things and email encryption, post-quantum cryptography and user-friendly security solutions were also discussed. Of course, cryptovision also provided information about its strategy following the acquisition by Atos, which offers fascinating new opportunities for customers of both companies.

For the first time, cryptovision also presented a Crypto Cave, where a real Enigma as well as other encryption machines could be marveled at. The Crypto Museum in Eindhoven provided these rare exhibits.

And of course the Mindshare wouldn’t be the Mindshare without the great Cryptonite party on the evening of the first conference day. Besides buffet, bar, live music and photo ball, fireworks were not to be missed.In this pleasant atmosphere there was ample opportunity for exchange of ideas and networking, which 450 participants did not miss.

For all those who missed the Mindshare and for all visitors who want to review the two days, cryptovision has published a video. In a good minute it faithfully reproduces the great Mindshare atmosphere:
