Smart cities, epistemic communities, advocacy coalitions and the 'last mile' problem Kitchin, Rob; Coletta, Claudio; Evans, Leighton; Heaphy, Liam; MacDonncha, Darach We argue that the ideas, ideals and the rapid proliferation of smart city rhetoric and initiatives globally have been facilitated and promoted by three inter-related communities: (i) `urban technocrats'; (ii) a smart cities `epistemic community'; (iii) a wider `advocacy coalition'. We examine their roles and the multiscale formation, and why despite their influence they encounter a `last mile problem'; that is, smart city initiatives are yet to become fully mainstreamed. We illustrate this last mile problem through a discussion of plans to introduce smart lighting in Dublin.

Nonanthropocentric design and smart cities in the anthropocene Luusua, Anna; Ylipulli, Johanna; Rönkkö, Emilia While the smart city agenda is critiqued for its focus on technology and business led solutions, a new approach to design has been introduced: nonanthropocentric design aims to decenter the human as the focus of design. We build on relevant works in Human-Computer Interaction (HCI) through discussing and comparing relevant theories in the social sciences and by analyzing design examples. This approach to HCI is necessary if humanity is to meet the challenges of the Anthropocene, the era in which human activity affects the Earth on a geological scale.

Blockchains and the crypto city Potts, Jason; Rennie, Ellie; Goldenfein, Jake Drawing on economic transaction cost theory, this paper explores how blockchain and distributed ledger technology could shift the smart city agenda by altering transaction costs with implications for the coordination of infrastructures and resources. Like the smart city the crypto city utilizes data informatics, but can be coordinated through distributed rather than centralized systems. The data infrastructure of the crypto city can enable civil society to run local public goods and services, and facilitate economic and social entrepreneurship.

Efficient implementation of ideal lattice-based cryptography Pöppelmann, Thomas Almost all practically relevant asymmetric cryptosystems like RSA or ECC are either based on the hardness of factoring or on the hardness of the discrete logarithm problem. However, both problems could be solved efficiently on a large enough quantum computer. While quantum computers powerful enough to break currently used parameter sets are not available yet, they are heavily researched and expected to reach maturity in 15 to 20 years. As a consequence, research on alternative quantum-safe cryptosystems is required. One alternative is lattice-based cryptography which allows the construction of asymmetric public-key encryption and signature schemes that offer a good balance between security, performance, and key as well as ciphertext sizes.
