This thesis describes hyper-encryption in the limited access model, a system that provides perfect secrecy and authentication against an adversary who possesses unbounded computational power, but who is limited in the ability to eavesdrop on more than a fraction of computers in a large network, such as the Internet. This thesis also presents an implementation of hyper-encryption in the limited access model, discusses areas where the theoretical system differs from the practical implementation, and analyzes their impact on the security of the system.</dim:field>
