Abstract
A communication apparatus and authenticating method prevent mistaken authentication at initial authentication in a connection between communication apparatuses. The communication apparatus includes an authentication processing unit which manages each state of the communication apparatus. The states include an authentication initiation permissible state, an authentication initiation impermissible state, an authentication initiation state, an authenticating state, an authentication successful state, an authentication unsuccessful state and an authentication completed state. Additionally, the authentication processing unit performs authentication with another communication apparatus, and stops the authentication when a plurality of authentication messages is received while in the authentication initiation state and the authenticating state. A conflict detection unit detects that a plurality of authentication messages has been received; a display unit displays each state; and an input unit accepts the state change from authentication initiation permissible to authentication initiation (an authentication initiation operation), and from authentication successful to authentication completed (an authentication completion operation).
