Question: I want to know what kind of Master Key sharing process is pursuit on Symmetric encryption environments (strictly symmetric, also in the key sharing scheme).
As I am aware there are several ways to establish the Master Key transportation and storage between two entities. The processes can pursuit a Key-Agreement or a Key-Transport scheme.
In key transportation a key wrapping function is used to protect the shared secret, then I assume that we do not need any public-key system such as DHKE or ECDH.
In key agreement asymmetric encryption processes are used to transport master keys between entities, then this is not a full symmetric master key exchange, correct?
Thanks in advance.
