Secure channel

In cryptography, a secure channel is a way of transferring data that is very difficult (called r"esistant") to overhear or copy (called "interception") and understand (called "decrypt") or change (called "tampering").
A confidential channel is a way of transferring data that is resistant to interception, but may not be resistant to tampering and may not be resistant to impersonation by someone else (called "spoofing").
An authenticatable channel is a way of transferring data that is resistant to spoofing but may not be resistant to interception or tampering.
