End-to-end encryption
With end-to-end encryption, data is encrypted so that only the sender and intended recipients can read it. Not even the provider can access the content.
What is end-to-end encryption?
End-to-end encryption (E2EE) is a method in which data is encrypted at the sender and only decrypted again at the intended recipient. Along the entire path in between, including at the provider itself, the content remains unreadable.
How does end-to-end encryption work?
Encryption and decryption take place on the devices of the communication partners. Only they hold the keys. Even if data were intercepted or viewed at the provider, it would be worthless without the matching key.
Difference from transport encryption
Transport encryption (such as TLS) only protects data on the transmission path. At the provider it is often available in decrypted form afterwards. With end-to-end encryption, by contrast, the provider has no access to the plaintext content.
AES-256 as a standard
A widely used encryption standard considered secure is AES-256. By today's standards it is regarded as practically unbreakable and is used to protect sensitive data.
How SecureCloud encrypts
SecureCloud encrypts data both in transit and at rest. This protects company data both on the move and while stored, hosted in Germany and GDPR-compliant.
Frequently asked questions
What is the difference between transport and end-to-end encryption?
Transport encryption only protects data on the way between device and server. End-to-end encryption protects the content throughout, so that even the provider cannot read it.
Is AES-256 secure?
AES-256 is considered very secure by the current state of the art and is used worldwide to protect sensitive data.
Why is encryption important for the GDPR?
The GDPR explicitly names encryption as a suitable technical measure for protecting personal data.
