En teknisk och säkerhetsmässig utvärdering av två aggregat för maskinell röjning
- 1991
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- En jämförelse av slag- och klingaggregat vid maskinell röjning visar att klingaggregatet är säkrast mot olycksfall, vilket är speciellt viktigt om maskinell och motormanuell röjning sker samtidigt. Klingaggregatet har lika hög prestanda och ger ett godtagbart resultat ur ekologisk synpunkt.

A Host Interface to the DTM Network
- 1992. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- DTM, dynamic synchronous transfer mode, is a new time division multiplexing technique for fiber networks currently being developed and implemented at the Royal Institute of Technology in Stockholm, Sweden. This paper describes the hardware and software aspects of the design of an SBus host interface to the DTM network for a Sun SPARCstation. The interface is based on a dual port memory residing on the interface card and accesible over the SBus from the host CPU. The host operating system allocates message buffers directly in this memory. The interface has hardware support for segmenting and reassembling packets to and from the data units of the DTM. The software part of the interface manages the shared memory and the virtual circuits provided by the DTM network.

Multimedia transport service and protocol issues
- 1992. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper considers the issues of a real time transport service needed by multimedia applications for transferring digital video and audio. Three classes of transport service are defined with different levels of real time constraints. Methods for error control are considered for the classes, and the classes are discussed with respect to the application requirements.

SPION: Secure Protocols in OSI Networks
- 1989. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- SPION: Secure Protocols in OSI Networks This report describes how security services can be realized in a computer network using the protocols of the Open Systems Interconnection (OSI) reference model for communication. The report starts with defining security requirements for a "typical" local area network in a company, university or similar organization. It is assumed that the organization does not use the network for transfer of extremely sensitive information, such as military secrets. A set of security services, as specified in the OSI security architecture, are selected in order to satisfy the requirements. The selected services are then placed in suitable layers of the OSI model according to the criteria in the security architecture, and to the taste of the authors. The report concentrates on the transport layer. An extension of the OSI transport protocol, class 4, including security services is described in detail. The protocol is a fully compatible extension of the standard transport protocol. Key management is another topic which is included in the report. A key management system for handling public keys and digital signatures based on an article by Dorothy E. Denning is described. The system includes functions for distributing and validating public keys, and registering and later verifying digital signatures. A key management protocol supporting these functions is defined for communication between ordinary open systems and special key server systems.

State of the art in network security
- 1990. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report is an effort to describe the state-of-the-art in computer network security focusing on the OSI Security architecture. Other sources of information include the NCSC "Trusted Network Interpretation of the TCSEC". The report describes the security threats imposed on networks and the countermeasures available. It gives a detailed description of the security services defined in the OSI Security architecture and the mechanisms proposed for realizing these services. An overview of security management with emphasis on key management is also included. The report contains numerous references to books and articles in the field of network security.
