In a wireless communications network including at least one authenticator and at least one authentication server, wherein the authenticator is adapted to interact with the authentication server for authenticating supplicants in order to conditionally grant thereto access to the wireless communications network, a short authentication method for authenticating a supplicant, the method including: providing a shared secret, shared by and available at the supplicant and the authentication server; having the supplicant provide to the authenticator an authentication token, wherein the authentication token is based on the shared secret available thereat; having the authenticator forward the authentication token to the authentication server; having the authentication server ascertain an authenticity of the received authentication token based on the shared secret available thereat; in case the authenticity of the authentication token is ascertained, having the authentication server generate a first authentication key based on the shared secret available thereat, and provide the generated authentication key to the authenticator; having the supplicant generate a second authentication key based on the shared secret; and having the supplicant and the authenticator exploit the generated first and the second keys for communicating with each other. The short authentication method is particularly useful in situations of handoff of the supplicant from an authenticator to another.

A method of detecting attacks in a wireless data communications network, includes: monitoring wireless traffic over the wireless data communications network; deriving a first network state from the monitored wireless traffic; acquiring trusted information indicative of a wireless network state from at least one apparatus of a network infrastructure; establishing a second network state based on the acquired trusted information; comparing the derived first network state with the second network state, and determining a wireless network attack in case of incoherence between the derived first network state compared to the second network state.

A method of enforcing security policies in a mobile ad-hoc network, includes: entrusting at least one first network node along a data traffic route from a data traffic origin node to a data traffic destination node, with the enforcing of predefined security policies on the data traffic; and entrusting at least one second network node, distinct from said first network node, with the control of the enforcement of the security policies by the first network node.
