stashcat® - The technology behind schul.cloud®

The technology behind schul.cloud® is based on the high-secure messenger stashcat®, which is currently being used by many authorities and companies. Read more about the security concept of stashcat® technology here.

End-to-end encryption

When sending messages, encryption is performed on the user's terminal, where the data is encrypted using a combination of AES (256-bit) and RSA (4096-bit) algorithms. All relevant data is  transmitted encrypted on the way to and from the server and stored there also encrypted.

  • Encrypted server
    The provisioning takes place centrally on encrypted, redundant servers, which are operated by MIVITEC GmbH in a high-security center in Munich. Regular, automatic online backups prevent data loss due to hardware failure, virus attack or force majeure.

  • Encrypted data exchange
    All relevant data is backed up in the second step by the latest SSL encryption methods. The backup takes place using a 256-bit AES SSL / TLS encryption on the way to our servers and encrypts the data exchange between server and terminal.
  • Encrypted messages
    In the third step, encryption is performed on the user's terminal, where the data is encrypted by a combination of AES and RSA algorithms. All relevant data is thus encrypted transmitted on the way to and from the server and stored there also encrypted.

Authorities that are using our stashcat® technology

Our highly secure technology is already being used by three state police forces - including the state police of Bremen and the state police of Lower Saxony (as NIMes).

With stashcat® 2016, a data protection compliant and secure Messenger for businesses and government agencies was created to close the need for confidential communication with file sharing.

Similar to educational institutions, there is a lack of a secure and valid alternative to WhatsApp for public authorities (especially BOS) such as police forces and companies. For example, companies use freely accessible messengers to engage in discussions with colleagues during a project and police to send wanted photos.

Problems such as industrial espionage, sabotage, data theft, abuse of privacy, lack of separation of professional and private communications as well as concerns about the privacy of personal data in particular, are an underestimated dangers of use.
