Secure channel
Return to Unsecure channel, confidential channel
- Snippet from Wikipedia: Secure channel
In cryptography, a secure channel is a means of data transmission that is resistant to overhearing and tampering. A confidential channel is a means of data transmission that is resistant to overhearing, or eavesdropping (e.g., reading the content), but not necessarily resistant to tampering (i.e., manipulating the content). An authentic channel is a means of data transmission that is resistant to tampering but not necessarily resistant to overhearing.
In contrast to a secure channel, an insecure channel is unencrypted and may be subject to eavesdropping and tampering. Secure communications are possible over an insecure channel if the content to be communicated is encrypted prior to transmission.
