Abstract
A portable communications device adapted to provide communications security and user identification, and authentication. In one embodiment, the device is useful with an untrusted network, and comprises security apparatus adapted to create associations with one or more security devices on the network. Traffic between the associated devices may be encrypted and residue-protected for e.g., data confidentiality and integrity protection. In one variant, the security apparatus comprises a software entity disposed at least partly within the software stack of a host. A security card may also be used as part of the security apparatus. The portable device may be untrusted (e.g., have an untrusted operating system) and also be physically unsecure. In one variant, the security apparatus is also agnostic to the portable device with which it is used.
