1 Objectives
* Confidentiality of the message. Only the authorized recipient should be able to extract the message content of the cypher. Furthermore, obtaining information about the content of the message is not possible once the cryptographic analysis becomes easier.
* Message integrity. The recipient must be able to determine if the message was altered during the transition.
* Authentication of the sender. The recipient should be able to identify the sender and verify who sent them the message.
* Irrevocability of the sender. It should not be possible to deny the authorship of the message.
2 How the objectives relate to information security management.
* Enhancing confidentiality by ensuring that only authorized recipient access the message so that it is not tempered with. It ensures that the message do not reach wrong people who may expose the message.
* Message integrity ensures that correct information is given and the same received without alteration.
* Authentication of the sender ensures that the information only come from the individuals who are authorized hence cannot insecure information to the company or an organization.
* Irrevocability of the sender determines the generator of the message. One should generate the relevant message needed by the organization.
