Landmark Cases in Property Law

This book explores the development of basic principles of property law in leading cases. Each paper considers a case on land, personal property or intangibles, discussing what that case contributes to the dominant themes of property jurisprudence - how are property rights acquired? What is the content of property rights? What are the limits or boundaries of property? How are property rights extinguished? Individually and collectively, the papers identify a number of important themes for the doctrinal development of property institutions and their broader justification. These themes include: the obscure and incremental development of seemingly foundational principles, the role of instrumentalism in property reasoning, the influence of the law of tort on the scope of property doctrines, and the impact of Roman legal reasoning on the common law of property. One or more of these themes (and others) is revealed through careful case analysis in each paper and they are collected and critically explored in the editors' introduction. This makes for a coherent and provocative collection.

Very high speed 17 Gbps SHACAL encryption architecture

Very high speed and low area hardware architectures of the SHACAL-1 encryption algorithm are presented in this paper. The SHACAL algorithm was a submission to the New European Schemes for Signatures, Integrity and Encryption (NESSIE) project and it is based on the SHA-1 hash algorithm. To date, there have been no performance metrics published on hardware implementations of this algorithm. A fully pipelined SHACAL-1 encryption architecture is described in this paper and when implemented on a Virtex-II X2V4000 FPGA device, it runs at a throughput of 17 Gbps. A fully pipelined decryption architecture achieves a speed of 13 Gbps when implemented on the same device. In addition, iterative architectures of the algorithm are presented. The SHACAL-1 decryption algorithm is derived and also presented in this paper, since it was not provided in the submission to NESSIE. © Springer-Verlag Berlin Heidelberg 2003.
