Abstract: This invention concerns methods for the protection of resources in an open digital communication system, which resources are residing in or owned by physically and organizationally distributed, independent entities connected through that system, e.g. the Internet. Since, in such an open system, any entity can in principle access any resource of any other entity, precautions must be taken to avoid or minimize the danger of resource corruption and destruction, to maintain privacy and, where necessary, confidentiality. Thus, protection of resources is of ultimate importance to warrant integrity and function of an entity. For the intelligent protection of such resources, in particular against unauthorized access, a variable-grained control of the name space (consisting of all names an entity provides) and/or the provision of attachable and detachable guards accompanying each call for a file and/or service is provided.

Abstract: The present invention provides methods, apparatus, and communication systems for the exchange of information in a networked pervasive environment. Therewith an authenticated and secure session can be achieved. Therefor are used a first device and at least a remote seco nd device. A unidirectional wireless communication channel between the first device and t he remote second device is initiated, whereby a sequence via the unidirectional wireless communication channel from the first device to the remote second device is sent in order to furnish the remote second device with encryption information. An encrypted response is sent via a wireless broadca st medium to the first device by using said encryption information for encryption.

Abstract: Scheme for advertising service offerings in a communications system comprising two devices, wherein a first of said two devices a. sends service information, comprising information about itself and/or other known devices i. chose timeout value TA, ii. listen for up to maximum time TA for service information sent by another device, iii. if TA timed out, continue with step a. otherwise, check whether said service information sent by another device comprises information about itself (local services); if yes, then continue with step i.; if no, then continue with step a.

Abstract: A computing device comprises a processor, a memory connected to the processor, and an application program stored in the memory and executable by the processor for generating data for communication to a remote computer system via a network based on a symbolic control information. A communications protocol stack is stored in the memory and executed by the processor for effecting communication of the data from the mobile device to the remote system. The protocol stack has an application layer for receiving the data from the application program and locating the data received in an application layer protocol data unit, and a network layer for receiving the application layer protocol data unit from the application layer, locating the application layer protocol data unit in a network layer protocol data unit, locating the symbolic control information in the network layer protocol data unit separately from the application layer protocol data unit, and forwarding the network layer protocol data unit to the network for transmission to the remote system.
