This article aims to contribute to recent debates on the politics of smart grids by exploring their installation in low-income areas in Kingston (Jamaica) and Rio de Janeiro (Brazil). To date, much of this debate has focused on forms of smart city experiments, mostly in the Global North, while less attention has been given to the implementation of smart grids in cities characterised by high levels of urban insecurity and socio-spatial inequality. This article illustrates how, in both contexts, the installation of smart metering is used as a security device that embeds the promise of protecting infrastructure and revenue and navigating complex relations framed along lines of socio-economic inequalities and urban sovereignty – here linked to configurations of state and non-state (criminal) territorial control and power. By unpacking the political workings of the smart grid within changing urban security contexts, including not only the rationalities that support its use but also the forms of resistance, contestation and socio-technical failure that emerge, the article argues for the importance of examining the conjunction between urban and infrastructural governance, including the reshaping of local power relations and spatial inequalities, through globally circulating devices.

ABSTRACT Objetive: to problematize the home care proposed by the Melhor em Casa Program as a safety device for understanding knowledge and conditions of possibility that support its discoursive network. Method: it is a study of genealogical inspiration about home care. The empirical material was constituted by legal documents about the theme, published in the Diário Oficial. The extracts that supposingly had the power to extract truth were organized in a spreadsheet. The analytic units were constructed, and instruments proposed by Foucault, such as power, biopolitics and device, were used for document analysis. Results: two analytic categories were elaborated: "From hospital to home", and "Home care: safety for the patient or for the State?". Conclusion: Home care, as a security device, proposes home as a safer and better place for the patient, who is close to the family, with no risk of hospital infection, cared by the health team, with the necessary technology.

Cryptography, which involves the use of a cipher, describes a process of encrypting information so that its meaning is hidden and thus, secured from those who do not know how to decrypt the information. Cryptography algorithms come with the various types including the symmetric key algorithms and asymmetric key algorithms. In this paper, the authors applied the most commonly used algorithm, which is the RSA algorithm together with the Chaos system and the basic security device employed in the worldwide organizations which is the Data Encryption Standard (DES) with the objective to make a hybrid data encryption. The advantage of a chaos system which is its unpredictability through the use of multiple keys and the secrecy of the RSA which is based on integer factorization’s difficulty is combined for a more secure and reliable cryptography. The key generation was made more secure by applying the DES schedule to change the keys for encryption. The main strength of the proposed system is the chaotic variable key generator that chages the value of encrypted message whenever a different number of key is used. Using the provided examples the strength of security of the proposed system was tested and demonstrated.

Security is needed in all places, especially in an institution where there are expensive and important equipment, therefore we need a security device system to facilitate handling as early as possible. In this case we can take advantage of technology that contains the concept of smart laboratory which is applied to the laboratory room of the electrical engineering faculty of Muhammadiyah University of Sidoarjo. By utilizing NodemCU as a microcontroller combined with a mini Arduino, RFID is a laboratory user identification that is used as a trigger for the locked or opening of the Doorlock solenoid, monitoring the opening and closing of the doorlock solenoid can be monitored or via a smartphone via a notification sent by nodemCU via the Blynk application platform, that the device create an internet of things system and monitor laboratory conditions in real time
