El secuestro de la justicia: Virtudes y problemas del sistema judicial

by Ignacio Escolar Joaquim Bosch Grau

¿Está la justicia española secuestrada por los políticos? Joaquim Bosch (ex portavoz de Juezas y Jueces para la Democracia) e Ignacio Escolar (director de eldiario.es) han unido fuerzas para escribir un libro necesario, incisivo y pedagógico sobre la Justicia. El sistema judicial está en crisis. Así lo denuncia esta reflexión crítica sobre un deterioro que afecta profundamente a nuestra democracia. En una escalada sin precedentes, las injerencias políticas son muy visibles, se concentran en la cúpula judicial y son especialmente peligrosas en los casos de corrupción. Por otro lado, la ciudadanía percibe que las leyes no siempre son iguales para todos. Las maniobras que tratan de capturar las instituciones judiciales están relacionadas con un fenómeno más amplio: los intentos de secuestro de la Justicia como valor. Por eso los autores también estudian: las injusticias que padecen las víctimas de violencia machista, y los que padecen abusos bancarios; los problemas en la aplicación de la prisión provisional o los excesos en los límites de la política de penas de privación de libertad; el drama de los refugiados y la criminalización de los inmigrantes; la falta de reparación de las víctimas del franquismo; la actuación de la justicia en el conflicto catalán; y los crecientes recortes de libertades. Pero El secuestro de la Justicia es también una defensa de la magnífica base del sistema judicial, esa inmensa mayoría de magistrados que no se ha dejado contaminar. Como los que llevaron los abusos bancarios a la jurisdicción europea y vencieron. O los que, sin medios suficientes, investigan la corrupción y ponen contra las cuerdas a políticos y a empresarios. La crítica ha dicho...«Relato pedagógico sobre separación de poderes.»EFE «Un texto ensayístico, pero escrito con estilo periodístico, orientado a plantear una larga serie de reflexiones y dudas sobre el llamado tercer poder.»Juan Bolea, El Periódico de Aragón «Un libro fundamentalpara entender nuestro país. No solo recomendable, sino imprescindible.»Carlos Ávila, Andamios (y la vida sigue)

Secure, Low-Power IoT Communication Using Edge-Coded Signaling

by Shahzad Muzaffar Ibrahim (Abe) Elfadel

This book discusses single-channel, device-to-device communication in the Internet of Things (IoT) at the signal encoding level and introduces a new family of encoding techniques that result in significant simplifications of the communication circuitry. These simplifications translate into lower power consumption, smaller form factors, and dynamic data rates that are tolerant to clock discrepancies between transmitter and receiver. Readers will be introduced to signal encoding that uses edge-coded signaling, based on the coding of binary data as counts of transmitted pulses. The authors fully explore the far-reaching implications of these novel signal-encoding techniques and illustrate how their usage can help minimize the need for complex circuitries for either clock and data recovery or duty-cycle correction. They also provide a detailed description of a complete ecosystem of hardware and firmware built around edge-code signaling. The ecosystem comprises an application-specific processor, automatic protocol configuration, power and data rate management, cryptographic primitives, and automatic failure recovery modes. The innovative IoT communication link and its associated ecosystem are fully in line with the standard IoT requirements on power, footprint, security, robustness, and reliability.

Securing Electricity Supply in the Cyber Age: Exploring the Risks of Information and Communication Technology in Tomorrow's Electricity Infrastructure

by Margot P. Weijnen Zofia Lukszo Geert Deconinck

The electricity infrastructure is one of society's most critical infrastructures. The complexity of the electricity infrastructure system is increasing quickly, due to the increasing intensity of market-based power exchanges between electricity systems, the associated market restructuring and an increasing share of decentralized generation. As a consequence, the organizational complexity of power systems has exploded. At the same time, there is a shift in public and societal goals towards low-carbon and sustainable power generation. This will eventually require a drastic transformation of the industry. Increasingly, ICT is being depended upon for managing this infrastructure, for technical control and operation and for facilitating markets. A recent example is demand-side management, based on detailed metering of consumption and decentralized electricity generation. The mutual dependence of the electricity and the ICT infrastructures raises challenging questions in the areas of dependability, security and resilience. Examples include vulnerability to (cyber) attacks, avoiding and repairing technical failures and protecting data confidentiality, while guaranteeing accessibility. Therefore, better models and methods for protection against exploits of system vulnerabilities, whether accidental or intentional such as in cyber attacks, are called for. To address the above mentioned problems an advanced research workshop: "Electricity security in the cyber age: Managing the increasing dependence of the electricity infrastructure on ICT" was organized in the Netherlands in May 2009. The objective of the workshop was to contribute to the security of current and future electricity infrastructures by analyzing the risks that are caused by the increasing reliance upon ICT and investigating options for managing these risks. The book presents the contributions to the workshop by distinguished invited keynote speakers and participants from the international scientific and industrial community.

The Securitisation of News in Turkey: Journalists as Terrorists? (The Palgrave Macmillan Series in International Political Communication)

by Natalie Martin

This book examines why Turkey has become infamous as a repressor of news media freedom. For the past decade or so it has stood alongside China as a notorious jailer of journalists – at the same time as being a candidate state of the EU. The author argues that the reasons for this conundrum are complex and whilst the AKP is responsible for the most recent illiberality, its actions should be taken in the wider context of Turkish politics – and the three way battle for power which has been raging between Kemalists, Kurds and Islamists since the republic was founded in 1923. The AKP are the current winners of this tripartite power struggle and the securitisation of journalists as terrorists is part of that quest. Moreover, whilst securitisation is not new, it has intensified recently as the number of the AKP’s political opponents has proliferated. Securitisation is also a means of delegitimising journalism – and neutralizing any threat to the AKP’s electoral prospects – whilst maintaining a democratic façade on the world stage. Lastly, the book argues that whilst the AKP’s securitisation of news began as a means of quashing the reporting of illiberality against wider political targets, since 2016 it has become a target in its own right. In the battle for power in Turkey, journalism is now one of the many losers.

Security and Privacy in Smart Grid (SpringerBriefs in Electrical and Computer Engineering)

by Asmaa Abdallah Xuemin Shen

This SpringerBrief addresses the main security concerns for smart grid, e.g., the privacy of electricity consumers, the exchanged messages integrity and confidentiality, the authenticity of participated parties, and the false data injection attacks. Moreover, the authors demonstrate in detail the various proposed techniques to secure the smart grid’s different communication networks and preserve the privacy of the involved. Over many years, power grid has generated electricity from central generators and distributed it in one direction from the generation stations to end-users; also, information is one directional so that the grid’s control center doesn’t get enough information about customers’ requirements and consequently can’t prevent electricity losses. So, the electricity grid is merged with information and communication technology to form smart grid. The main target of this incorporation is to connect different parties of power grid to exchange information about grid conditions and customers’ requirements, and consequently, improve the reliability and efficiency of electricity generation and distribution. That upgrade of the power grid exposes it to the cyber security threats that the communication networks suffer from, such as malicious attacks to forge the electricity consumption readings or price, extract personal information for residential consumers, such as daily habits and life style, or attack some grid’s resources and equipment availability using denial-of-service attacks. Also, novel threats are introduced in smart grid due to the power grid nature, such as false data injection attack, in which the adversary compromises several measurement units and injects false information about the grid conditions that mislead the grid’s control center to make wrong decisions for the grid and consequently impact on its stability and efficiency.

Security Assessment in Vehicular Networks

by Suguo Du Haojin Zhu

This book presents several novel approaches to model the interaction between the attacker and the defender and assess the security of Vehicular Ad Hoc Networks (VANETs). The first security assessment approach is based on the attack tree security assessment model, which leverages tree based methods to analyze the risk of the system and identify the possible attacking strategies the adversaries may launch. To further capture the interaction between the attacker and the defender, the authors propose to utilize the attack-defense tree model to express the potential countermeasures which could mitigate the system. By considering rational participants that aim to maximize their payoff function, the brief describes a game-theoretic analysis approach to investigate the possible strategies that the security administrator and the attacker could adopt. A phased attack-defense game allows the reader to model the interactions between the attacker and defender for VANET security assessment. The brief offers a variety of methods for assessing the security of wireless networks. Professionals and researchers working on the defense of VANETs will find this material valuable.
