The invention provides a vehicle security device with an electronic use-authorization coding arrangement for preventing unauthorized access to the vehicle. The vehicle security device utilizes digital signature algorithm for encrypting and transmitting authorization and synchronization information, so that the storage of secret information is essential only at the key unit in order to transmit authorization and/or synchronizing information from the key unit to the vehicle unit in a way which is very effectively protected against falsification. Thus, reading out vehicle unit information does not permit unauthorized manufacture of a copied key.

Vehicle security device with electronic use authorization coding

This paper provides an overview of the LOKI encryption primitive which may be used to encrypt and decrypt a 64-bit block of data using a 64-bit key. The LOKI primitive may be used in any mode of operation currently defined for ISO DEA-1, with which it is interface compatible [AAAA83]. Also described are two modes of operation of the LOKI primitive which compute a 64-bit, and 128-bit, Message Authentication Code (or hash value). These modes of operation may be used to provide authentication of a communications session, or of data files.

LOKI—a cryptographic primitive for authentication and secrecy applications

The hash functions MD5, RIPEMD-160, and SHA-1/224/256/384/512 were implemented by using a 0.13/spl mu/m CMOS standard cell library with two synthesis options, area and speed optimizations, and their performances were evaluated. The smallest circuit of 8.0 Kgates with a throughput of 929 Mbps, and the highest throughput of 2.9 Gbps with 27.3 Kgates were obtained for SHA-1 and SHA-384/512 respectively. In terms of overall performance with consideration of the security levels, we conclude that SHA-256 is the best algorithm, with compact circuits of 11.5 /spl sim/ 15.3 Kgates and high throughputs of 1.1 /spl sim/ 2.4 Gbps. Our implementations also showed the highest throughputs for all of the hash functions in comparison with the state of the art.

The first aim of this paper is to situate the call for integrity and authentication algorithms within research on cryptography and within evolution of telecommunication. Motivations for submitting primitives and details on the submission process are also given.

A European call for cryptographic algorithms: ripe, race integrity primitives evaluation

Early in 1989, a call for integrity primitives was disseminated within the cryptographic community by the RIPE consortium. The goal of this consortium is to put forward an ensemble of techniques to meet the anticipated requirements of the future Integrated Broadband Communication Network in the European Community. The aim of this paper is to describe the status of the RIPE project.

Race integrity primitives evaluation (RIPE): a status report

Race Integrity Primitives Evaluation (RIPE): A Status Report

RIPE integrity primitives Part II Final report of RACE 1040

Due to security requirements, services and management of Integrated Broadband Communication (IBC) are crucially dependent on the use of cryptographic techniques. Within the RACE program (Research and Development in Advanced Communications Technologies in Europe), the RIPE project (RACE Integrity Primitives Evaluation) aims to put forward a portfolio of such techniques to meet the anticipated security requirements of IBC. The goal of this contribution is to describe background and status of the RIPE project.
