As data outsourcing services have been becoming common recently, developing skills to search over encrypted data has received a lot of attention. Order-revealing encryption (OREnc) enables performing a range of queries on encrypted data through a publicly computable function that outputs the ordering information of the underlying plaintexts. In 2016, Lewi et al. proposed an OREnc scheme that is more secure than the existing practical (stateless and non-interactive) schemes by constructing an ideally-secure OREnc scheme for small domains and a “domain-extension” scheme for obtaining the final OREnc scheme for large domains. They encoded a large message into small message blocks of equal size to apply them to their small-domain scheme, thus their resulting OREnc scheme reveals the index of the first differing message block. In this work, we introduce a new ideally-secure OREnc scheme for small domains with shorter ciphertexts. We also present an alternative message-block encoding technique. Combining the proposed constructions with the domain-extension scheme of Lewi et al., we can obtain a new large-domain OREnc scheme with shorter ciphertexts or with different leakage information, but longer ciphertexts.

Universal, predictive attractor patterns configured by Lyapunov exponents (LEs) as a function of the control parameter are shown to characterize periodic windows in chaos just as in attractors, using a coherent model of the laser with injected signal. One such predictive pattern, the symmetric-like bubble, foretells of an imminent bifurcation. With a slight decrease in the gain parameter, we find the symmetric-like bubble changes to a curved trajectory of two equal LEs in one attractor, while an increase in the gain reverses this process in another attractor. We generalize the power-shift method for accessing coexisting attractors or periodic windows by augmenting the technique with an interim parameter shift that optimizes attractor retrieval. We choose the gain as our parameter to interim shift. When interim gain-shift results are compared with LE patterns for a specific gain, we find critical points on the LE spectra where the attractor is unlikely to survive the gain shift. Noise and lag effects obscure the power shift minimally for large domain attractors. Small domain attractors are less accessible. The power-shift method in conjunction with the interim parameter shift is attractive because it can be experimentally applied without significant or long-lasting modifications to the experimental system.

Indonesian reformation era begins with the fall of President Suharto. Political transition and democratic transition impact in the religious life. Therefore, understandably, when the politic transition is not yet fully reflects the idealized conditions. In addition to the old paradigm that is still attached to the brain of policy makers, various policies to mirror the complexity of stuttering ruler to answer the challenges of religious life. This challenge cannot be separated from the hegemonic legacy of the past, including the politicization of SARA. Hegemony that took place during the New Order period, adversely affected the subsequent transition period. It seems among other things, with airings various conflicts nuances SARA previously muted, forced repressive. SARA issues arise as a result of the narrowing of the accommodation space of the nation state during the New Order regime. The New Order regime has reduced the definition of nation-states is only part of a group of people loyal to the government to deny the diversity of socio-cultural reality in it. To handle the inheritance, every regime in the reform era responds with a pattern and a different approach. It must be realized, that the post-reform era, Indonesia has had four changes of government. The leaders of every regime in the reform era have a different background and thus also have a vision that is different in treating the problem of racial intolerance, particularly against religious aspect. This treatment causes the accomplishment difference each different regimes of dealing with the diversity of race, religion and class that has become the hallmark of Indonesian society.

Copenhagen summit results could be called a failure. This is the failure of UN climate change policy management, but definitely the first step to a new order as well. The article reviews main characteristics of climate policy paradigm shifts. Russian interests in climate change policy and main threats are analyzed. Successful development and implementation of energy savings and energy efficiency policy are necessary and would sufficiently help solving the global climate change problem.

In line with the times demand, nationlism changes as a dynamic of dialectics proceeds with changes in social, political, and ekonomic in the country and global levels. Based on a review of historical chronology, this paper analyzed descriptively the relationship between Islam and nationalism in Indonesia. Since the early growth of nationalism and the Dutch colonization period in Indonesia, Islam became the spirit of sacrifice of lives and property of the Indonesian people's fighting to get independence and on the Japanese colonial period and the early days of independence, Islam through the muslim leaders founction as base of departure and developer awareness of nasionalism, patriotism and unity to defend the independence. Despite the authoritarian New Order ruler cope with Islam through the establishment of the Association of Indonesian Muslim Intellectuals (ICMI), but awareness of national Muslim leaders to build Indonesia managed to push governance reforms. And in this era of reform, the spirit of nationalism and the spirit of sacrifice of the Indonesian leaders increasingly eroded by corruption. Key words: proto-nationalism, political nationalism, cultural nationalism.

Points Of View

This article explores how gender representations are deployed in anthropological analysis with reference to female performers (ledhek) in rural Java during the last decades of Suharto's New Order Indonesia (1966–1998). 1 It shows how the negative ascriptions given to ledheks were consistent with state promulgated gender ideologies in Indonesia, and explores the women's experiences in performances and everyday life. This different standpoint allows us to understand their dancing from the performers’ points of view, rather than from that of official state endorsed ideas of acceptable performance culture.

This book explores the transformation of Turkey’s political regime from 2002 under the AKP rule. Turkey has been through a series of major political shifts historically, roughly from the mid-19th century. The book details the most recent change, locating it in its broader historical setting. Beginning with the AKP rule from late 2002, supported by a wide informal coalition that included liberals, it describes how the ‘former’ Islamists gradually acquired full power between 2007 and 2011. It then chronicles the subsequent phase, looking at politics and rights under the amorphous new order. This highly accessible assessment of the change in question places it in the larger context of political modernisation in the country over the past 150 or so years, covering all of the main issues in contemporary Turkish politics: the religious and secular divide, the Kurds, the military, foreign policy orientation, the state of human rights, the effective concentration of powers in the government and a rule by policy, rather than law, initiated by Erdogan’s increasingly authoritarian populism. The discussion at once situates Turkey in the broader milieu of the Arab Spring, especially in terms of Islamist politics and Muslim piety in the public sphere, with some emphasis on ‘Islamo-nationalism’ (Millî Görüş) as a local Islamist variety. Effortlessly blending history, politics, law, social theory and philosophy in making sense of the change, the book uses the concept of mimesis to show that continuity is a key element in Turkish politics, despite the series of radical breaks that have occurred.
