Use an example in security design to demonstrate the use of the Separation of Privilege principle.
The main characteristic of the Public Key Infrastructure (ICP) – or Public Key Infrastructure (PKI) – is that it uses a pair of keys, public and private, to provide the underlying security services. Regarding aspects related to the security of a cryptographic system, analyze the following statements.
I. Typically, what compromises the security of a cryptographic model has less to do with the design of that model and more to do with poor key management.
II. Private keys must remain secret from all parties involved, throughout their lifecycle, including the owners of those keys, which is why they are also called secret keys.
III. Because public keys are in the open domain they can be tampered with, there is no guarantee that a public key is correct. The infrastructure by which they are managed must be trusted.
IV. A public key infrastructure (or Public Key Infrastructure - PKI) guarantees some aspects related to the life cycle of a public key, such as generation, installation and…
Is authentication needed in any unusual situations? When comparing authentication methods, which ones offer the biggest upsides and downsides?
