Masquerade

Public Announcement is a way of #public key distribution method where users directly distribute the public keys to recipients or broadcast over the Internet. It is susceptible to forgery as people could create a key and claiming to be someone else#.

Peer Entity Authentication is a kind of #Security Service that utilises encryption#, Digital Signature# and Authentication Exchange# in order to counter Masquerade#.

Fabrication is a form of #Security Attack aims at forging an identity, pretending to be an authenticated entity. It undermines the authenticity# of the system. Masquerade# and Server-Side Request Forgery (SSRF)# are one of the example.

Data Origin Authentication is a kind of #Security Service that utilises encryption# and Digital Signature# in order to counter Masquerade#.

Authenticity is a quality of how true or authentic the entity is the one as claimed. There are several threats to Authenticity such as physical access to authenticated device, impersonation of authenticated device by masking its Media Access Control Address (MAC) (Masquerade), and gaining entrance to server or disrupting operations with Replay Attack. This could be avoid with cryptographic techniques.

It could be used as a counter of Masquerade# so that none of the unauthorised source could access resources without permission.
