Abstract The Internet of Things (IoT) has experienced rapid development in area-specific applications, including smart transportation systems, healthcare, industries, and smart agriculture, to enhance socio-economic development over the past few years. This IoT system includes different actuators, interconnected sensors, and network-enabled devices that exchange various data through private networks and the Internet infrastructure. The intrusion detection system (IDS) is deployed with preventive security mechanisms, namely access control and authentication. The usual behaviors of the mechanism distinguish malicious and normal activities based on specific patterns or rules of IDSs. Therefore, this article focuses on developing IDS using Double Adaptive Weighting Arithmetic Optimization Algorithm with Deep Learning (DAWAOA-DL) approach in the IoT environment. The DAWAOA-DL methodology's objective is to recognise and classify intrusions in the IoT platform accurately. To execute this, the presented DAWAOA-DL approach involves the design of the DAWAOA technique for the feature selection procedure. Next, the convolutional neural network-gated recurrent unit (CNN-GRU) technique is used for the intrusion detection task. Finally, the Adam optimizer is exploited as a hyperparameter optimizer of the CNN-GRU methodology. A series of simulations were performed on the BoT-IoT dataset to exhibit the effectual detection performance of the DAWAOA-DL method. A widespread experimental validation demonstrated the betterment of the DAWAOA-DL method over other recent models under several metrics.

Abstract The Trust-Aware Aggregation Authentication Protocol for SIoT Networks is a security process intended for SIoT platforms. It concentrates on ensuring the reliability of communication and data aggregation between interrelated IoT devices. This protocol deploys authentication systems for verifying the identities of devices and integrates trust-aware mechanisms to estimate the trustworthiness of data exchanged from the social environment of SIoT. By establishing a trustworthy and secure communication structure, this protocol improves the entire integrity and security of SIoT networks, addressing potential vulnerabilities connected with social communications between IoT devices. Therefore, this study develops an enhanced Trust Management using Locally Weighted Salp Swarm Algorithm with Deep learning (ETM-LWSSADL) technique for SIoT Networks. The ETM-LWSSADL technique computes direct and indirect trust values and is assessed depending upon different weighing factors for maximizing the application performance and creating a secure data transmission process. During authentication process, when the SIoT device with total trust value (TTV)is not greater than the threshold value (THV) or authentication token is invalid, the gateways then disregard the node. Besides, bidirectional gated recurrent unit (BiGRU) model is applied to generate a THV on collected traffic data. Moreover, the ETM-LWSSADL technique exploits the LWSSA technique for optimum hyper parameter selection of the BiGRU algorithm. To highlight the enhanced performance of the ETM-LWSSADL methodology, an extensive range of simulations can be involved.

NoSQL databases have gained a lot of popularity over the last few years. They are now used in many new system implementations that work with vast amounts of data. Such data will typically also include sensitive information that needs to be secured. NoSQL databases are also underlying a number of cloud implementations which are increasingly being used to store sensitive information by various organisations. This has made NoSQL databases a new target for hackers and other state sponsored actors. Forensic examinations of compromised systems will need to be conducted to determine what exactly transpired and who was responsible. This paper examines specifically if NoSQL databases have security features that leave relevant traces so that accurate forensic attribution can be conducted. The seeming lack of default security measures such as access control and logging has prompted this examination. A survey into the top ranked NoSQL databases was conducted to establish what authentication and authorisation features are available. Additionally the provided logging mechanisms were also examined since access control without any auditing would not aid forensic attribution tremendously. Some of the surveyed NoSQL databases do not provide adequate access control mechanisms and logging features that leave relevant traces to allow forensic attribution to be done using those. The other surveyed NoSQL databases did provide adequate mechanisms and logging traces for forensic attribution, but they are not enabled or configured by default. This means that in many cases they might not be available, leading to insufficient information to perform accurate forensic attribution even on those databases.

In almost all watermarking-based document authentication systems, the documents are considered as binary images and then, the watermark is embedded using some image watermarking algorithm. However actually important documents are saved using document file formats, such as Portable Document Format (PDF) or Open Document Format (ODF), among others, because in general the file size is smaller compared with an image file, and also these are considered as more secure than other types of file format. However, the documents with these formats can also be maliciously modified for illegal purposes, making necessary the development of mechanisms that are able to detect such modifications. Considering the situations mentioned above, this paper proposes a document authentication scheme in which a watermark is directly embedded into the document file format as part of the document itself. The experimental results show a desirable performance of the proposed algorithm.

Nowadays, we can easily obtain variety of services through networks. But due to the open environment, networks are vulnerable to many security threats. The remote user authentication scheme is one of the most widely used mechanisms for servers to authorize users to access the services. In 2009, Ramasamy and Muniyandi proposed a discrete logarithm based remote authentication scheme with smart cards. Their scheme provides mutual authentication and withstands the denial of service attack, forgery attack and parallel session attack. In this article, we show that their scheme is not a practical solution for remote access. It lacks key agreement mechanism and users cannot choose or update passwords freely. Moreover, their scheme cannot resist the stolen-verifier attack, off-line guessing attack, impersonation attack and smart-card-loss-attack. We propose an improved scheme to remedy the drawbacks. The improved scheme has the merits of providing mutual authentication and key agreement, while forward and backward secrecy are ensured as well. The users can choose and update their passwords freely. Furthermore, the scheme can also withstand many attacks such as the smart-card-loss-attack, the replay attack, the off-line guessing attack, the insider attack, the impersonation attack and the parallel session attack.

In January 2005, the Mexican Tributary Administration System (SAT) introduced an official norm that stipulates how to generate electronic invoices that were termed by SAT, Comprobante Fiscal Digital (CFD). Supporting the CFD service implies the exchange of confidential information over Internet and other communication channels that are intrinsically highly vulnerable. Therefore, it becomes indispensable to incorporate to this service reliable and sound information security mechanisms. In the case of SAT's CFD, its security guarantees depend on customary cryptographic mechanisms such as, digital signatures, hash functions, etc. In this paper we point out several security flaws in the procedure specified by SAT for generating such electronic invoices. Furthermore, we provide recommendations for avoiding the security problems detected, which include the usage of more robust cryptographic mechanisms, alternative authentication protocols, time stamps authorities and a safe storage system.

En enero de 2005, el Gobierno mexicano a través del Servicio de Administración Tributaria (SAT), presentó una norma oficial que estipula cómo generar facturas electrónicas, las cuales recibieron el nombre oficial de Comprobante Fiscal Digital (CFD). El hecho de ofrecer el servicio de CFD implica el intercambio de información confidencial que debe viajar por Internet y otros canales de comunicación que son intrínsecamente altamente vulnerables. Por lo tanto, es indispensable incorporar a dicho servicio, herramientas de seguridad confiables y técnicamente sólidas. En el caso de los comprobantes fiscales digitales del SAT, su seguridad depende de mecanismos criptográficos tradicionales tales como, firmas digitales, funciones picadillo, etc. En este artículo se señalan fallas de seguridad en el procedimiento especificado por el SAT para la generación de sus facturas electrónicas. Aunado a esto, en este trabajo se dan algunas recomendaciones para eliminar los problemas de seguridad detectados, lo cual incluye, el uso de mecanismos criptográficos más robustos, protocolos de autentificación alternativos, autoridades que emitan estampillas de tiempo y un sistema de almacenamiento a largo plazo seguro.
