The Corona break was long, but since autumn 2021 trade fairs and congresses have been held again in the computer industry. Also cryptovision is happy about this piece of regained normality. Last week cryptovision employee Klaus Schmeh took the opportunity and made his way to Berlin for a lecture. At the Signaturtag, organized by TeleTrusT and VOI, he gave a presentation on the topic “The three most important post-quantum signature procedures explained clearly”.
Schmeh’s goal of making the subject of post-quantum cryptography understandable to laypersons is no easy task, because the various procedures are mathematically extremely demanding. In the meantime, it has become clear which of the many dozens of post-quantum methods will prevail in practice. Among the favorites are also five signature methods that have already been standardized or have reached the final round in the post-quantum competition of the U.S. authority NIST. Schmeh presented three of these algorithms in his talk.
For his presentation, the long-time cryptovision employee used, as usual, his original slides in cartoon design and vivid analogies from everyday life. Even listeners without a mathematics or computer science degree got an idea of how CRYSTALS-DILITHIUM, Rainbow or extended Merkle signatures work.
After the successful start, the trade fair and congress autumn continues for cryptovision. From October 12 to 14, it-sa in Nuremberg is on the agenda.

The IT system house of the German Armed Forces, BWI, has concluded a contract with cv cryptovision GmbH for the use of the GreenShield e-mail security software. Based on a corporate license, more than 160,000 communication subscribers will be successively equipped with the security software for e-mail encryption and digital signature. Cryptovision has been supplying the Bundeswehr with email security software for the electronic processing of classified information up to the classification level “VS-Nur den Dienstgebrauch” (VS-NfD) since 2004.
GreenShield protects e-mails and files on the basis of end-to-end encryption and enables the recipient to verify the integrity of the content and the sender by means of digital signatures. A decisive unique selling point is the interoperability of the cryptovision solution: GreenShield is the only email encryption solution for IBM / HCL Notes on the German market that has been approved by the German Federal Office for Information Security (BSI). The solution’s multi-client capability is also unique: it supports both Outlook and Notes on the same device. Thus, GreenShield enables a smooth migration from Notes to Outlook.
The encryption of files and e-mails is done with just a few clicks and intuitively for the user in the familiar environment of his e-mail program. The GreenShield plug-in integrates seamlessly into the email program as an additional layer of security and offers both users and administrators many additional convenience features.
In NATO jargon, information security is referred to as “Information Assurance” (IA), and it is not surprising that the military alliance places great emphasis on this topic. Members of the organization are only allowed to use IA solutions that are specifically approved for NATO. Which products have cleared the high approval hurdles can be found in the “NATO Information Assurance Product Catalogue” (NIAPC), which is available online. Since last week, NATO has also listed GreenShield from cryptovision there.
GreenShield is one of the few encryption solutions approved in Germany for information classified “Verschlusssache – Nur für den Dienstgebrauch” (VS-NfD). This applies to both email encryption with GreenShield Mail and file encryption with GreenShield File. Both versions also have the “NATO RESTRICTED” (NR) approval.
By receiving NR approval, GreenShield also qualified for the NATO product catalog. GreenShield Mail and GreenShield File are listed with two separate entries, including screenshots and brochures.
cryptovision is well known in the exclusive NATO catalog. The predecessor product s/mail has been there for years, it also has the necessary NR approval.

The damage caused by cyber attacks on German companies is increasing at an alarming rate. While it was still 103 billion euros per year in 2018/2019, the German economy already had to accept 223 billion in damage from digital attacks in 2020/21. This is the result of a representative study by the digital association Bitkom, for which more than 1,000 companies across all industries were surveyed.
According to the study, ransomware attacks are particularly frequent and dangerous. The criminals now not only threaten to destroy the affected data if the victim does not pay. Rather, it is also popular to publish the data if the ransom is refused – for many companies, this is an even bigger nightmare than data loss. In addition to ransomware, other forms of cybercrime are booming, including cyber espionage and data theft.
The Bitkom study makes it clear once again that every company should encrypt important files and e-mails. Because as soon as information is reliably encrypted, it becomes virtually worthless to cyber spies and data thieves. The ransomware threat to publish the stolen data if the ransom is not paid also comes to nothing if the data is encrypted.
The frightening increase in cyber attacks is one more reason to choose cryptovision’s GreenShield software. GreenShield offers both email and file encryption at the highest level. The product can look back on a 15-year development history, during which cryptovision has always placed great emphasis on user-friendliness. The two formats S/MIME and PGP are equally supported. GreenShield is therefore extremely easy and intuitive to use. Furthermore, GreenShield is one of the very few encryption solutions that have been approved by the German Federal Office for Information Security (BSI) for data of the security level “Classified Information – For Official Use Only” (VS-NfD). This approval proves that the product meets the highest security requirements. NATO also lists GreenShield File and GreenShield Mail on its website.
It is not only the Bitkom study that shows that IT security measures are becoming increasingly important. A look at the GreenShield website is therefore worthwhile.
