Definition Edit

Identity confidentiality is

[a] property of an individual where only the recipient can sufficiently identify the individual within a set of other individuals. This can be a desirable property of authentication protocols.[1]

Overview Edit

"An initiator has identity confidentiality when any party other than the recipient cannot sufficiently identify the initiator within the anonymity set. The size of the anonymity set has a direct impact on identity confidentiality, since the smaller the set is, the easier it is to identify the initiator. Identity confidentiality aims to provide a protection against eavesdroppers and intermediaries rather than against the intended communication endpoints."[2]
