Remarks
Combination of;
- Entity AuthenticationMechanisms that allow for checking the integrity of the data transmitted.
- Key Exchange DICOM calls this “Exchange of Master Secrets”. This is the method that is used to exchange the symmetric key to be used for encoding the messages
- Data IntegrityMechanisms that allow for checking the integrity of the data transmitted.
- PrivacyMechanisms that allow for encrypting the data sent.
