The Cultural Heritage of Pilgrim Itineraries: The Camino de Santiago

The Camino de Santiago comprises a lattice of European pilgrimage itineraries which converge at Santiago de Compostela in north-west Spain. This Working Paper introduces the historical and contemporary representation of these routes as a heritage complex that is imagined and codified within varied cultural meanings of a journey undertaken. Particular attention is given to the Camino Frances and the Via de la Platawhich contrast as mature and formative pilgrimage settings. Within this spatial sphere, the analysis deals with the Camino de Santiago as official heritage, as development instrument, as civil society, and as personal experience. The paper concludes by critically reviewing a previous conceptualisation of pilgrim route-based tourism, derived from fieldwork completed in 1994. Some substantive additions to that model are then advanced which arguably fit better with the many context changes that have occurred over the past two decades.

The Cultural Heritage of Pilgrim Itineraries: The Camino de Santiago

The Camino de Santiago comprises a lattice of European pilgrimage itineraries that converge at Santiago de Compostela in northwest Spain. This article introduces the historical and contemporary representation of these routes as a heritage complex that is imagined and codified within varied cultural meanings of a journey undertaken. Particular attention is given to the Camino Frances and the Via de la Plata, which contrast as mature and formative pilgrimage settings. Within this spatial sphere, the analysis deals with the Camino de Santiago as official heritage, as development instrument, as civil society, and as personal experience. The article concludes by offering a contemporary conceptualization of the evolving Camino de Santiago cultural heritage complex.

Improving RO PUF design using frequency distribution characteristics

A Physical Unclonable Function (PUF) can be used to provide authentication of devices by producing die-unique responses. In PUFs based on ring oscillators (ROs) the responses are derived from the oscillation frequencies of the ROs. However, RO PUFs can be vulnerable to attack due to the frequency distribution characteristics of the RO arrays. In this letter, in order to improve the design of RO PUFs for FPGA devices, the frequencies of RO arrays implemented on a large number of FPGA chips are statistically analyzed. Three RO frequency distribution (ROFD) characteristics, which can be used to improve the design of RO PUFs are observed and discussed.

RO PUF Design in FPGAs with new comparison strategies

A Physical Unclonable Function (PUF) can be used to provide authentication of devices by producing die-unique responses. In PUFs based on ring oscillators (ROs), the responses are derived from the oscillation frequencies of the ROs. However, RO PUFs can be vulnerable to attack due to the frequency distribution characteristics of the RO arrays. In this paper, in order to improve the design of RO PUFs for FPGA devices, the frequencies of RO arrays implemented on a large number of FPGA chips are statistically analyzed. Three RO frequency distribution (ROFD) characteristics are observed and discussed. Based on these ROFD characteristics, two RO comparison strategies are proposed that can be used to improve the design of RO PUFs. It is found that the symmetrical RO comparison strategy has the highest entropy density.
