GCM
Abbreviation for Galois/Counter Mode
In short and in plain language
GCM is a mode used by methods that encrypt data.
It encrypts the data and at the same time makes it possible to notice changes.
It is often used for encrypted web connections.
Many processors support it directly. This can keep the work load of the server low.
Definition
GCM is a mode of operation for encryption methods that encrypts data and at the same time makes tampering detectable. It is widely used for encrypted web connections. Many processors support it directly, which can keep the server's computing load low.
