Abstract
A portable communications device adapted to provide communication security in, for example, an ad hoc or temporary networked environment. In one embodiment, the network comprises an untrusted medium, and the device includes network security apparatus adapted to create security associations between devices on the network, including mutual authentication. Traffic between the associated devices may be encrypted for e.g., data confidentiality and integrity protection. In one variant, the network security apparatus comprises a software entity disposed at least partly within the software stack of the device. The device may be untrusted (e.g., have an untrusted operating system). User identification or validation may also be provided, for example via inputs received via a user interface.
