End-to-end encryption

In end-to -end encryption (English "end -to-end encryption", " E2EE " ) means away the encryption of transmitted data over all transmission stations.

The data to be transmitted and are ver - decrypted only on the transmitter side again at the receiver. This allows side-channel information as they partly arise, for example, to control the transfer process, are not encrypted, on the other hand will connive at intermediate stations at which there are content being transferred in plain text, eliminated.

A counterpart is the point-to- point encryption, with which it can be nested in combination. Common technique for end-to -end encryption, for example, OpenPGP and S / MIME for e -mail traffic or OTR for instant traffic and ZRTP / SRTP in Audio-/Video-Chats and SIP telephony.
