Cryptosystem

In cryptography, a cryptosystem is a suite of cryptographic algorithms needed to implement a particular security service, such as confidentiality. Typically, a cryptosystem consists of three algorithms: one for key generation, one for encryption, and one for decryption.

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, but not necessarily resistant to tampering (i.e., manipulating the content).
