Natural language access control configuration
Patent published on the 2026-10-15 in WO under Ref WO2026214869 by DORMAKABA DEUTSCHLAND GMBH [DE] (FiÉvet Alexis [de], Appl Dominik [de], Schwarz Dieter [de], Kanstein Volker [de])
Abstract: A computer-implemented method manages an access control platform by receiving a natural language request from a user via a user interface. The request, formulated in natural language and describing a configuration operation relating to the access control platform, is processed by a language model that determines the intended configuration operation to be performed on the platform. The method causes the performing of the determined configuration operation on the access control platform. This enab[...]
Our summary: This method allows users to configure an access control platform using natural language requests. A language model processes these requests to determine the intended configuration operations. This approach simplifies management and automates configuration tasks, making it accessible to non-technical users.

Methods for identity attestation and devices thereof
Patent published on the 2026-10-15 in WO under Ref WO2026213765 by HUAWEI TECH CO LTD [CN] (Laitinen Pekka [cn], Li Qiming [cn], Lian Gang [cn], Tamrakar Sandeep [cn], Liu Zhiwei [cn])
Abstract: Embodiments of the invention relate to methods for identity attestation. Thus, a security system of a device transmits a certificate signing request to a public key infrastructure, the certificate signing request indicating at least one ID of the device. The public key infrastructure generates at least one first ID check value (IDcheck1) by inputting the at least one ID of the device and at least one nonce value into a function (fcheck); and thereafter transmits an attestation certificate to the[...]
Our summary: The invention describes methods for identity attestation using a security system that transmits a certificate signing request to a public key infrastructure. The infrastructure generates an ID check value and sends an attestation certificate back to the security system. This certificate can be utilized by applications on the device to request services.

Approaches for securing database management operations
Patent published on the 2026-10-15 in US under Ref US20260320211 by SALESFORCE INC [US] (Balaka Jyothi Babu [us])
Abstract: Methods and corresponding systems and apparatuses for securing database management operations are described. A request to propagate a database management operation through a first containerized database instance to one or more different containerized database instances may be determined. A determination may be made that the request satisfies at least one access control restriction to perform the database management operation. A determination may be made that the request to perform the database m[...]
Our summary: Methods for securing database management operations are outlined. The process includes determining access control restrictions for propagating operations between containerized instances. Execution is managed based on network scope configurations.

Patent
Electronic device and information security protection method thereof
Patent published on the 2026-10-15 in US under Ref US20260323302 by ASUSTEK COMPUTER INC [TW] (Liu I-hsien [tw], Shen Wei-jhih [tw], Wang Chih-kai [tw], Lu Chun-liang [tw], Syu Jhih-rong [tw])
Abstract: Provided are an electronic device and an information security protection method thereof. The method comprises the following steps. A pairing procedure between the electronic device and an external electronic device is performed. Through a first ultra-wideband device of the electronic device, a distance between the external electronic device including a second ultra-wideband device and the electronic device is detected. The electronic device is controlled to operate in a locked state or an unlock[...]
Our summary: The method involves pairing an electronic device with an external device. It uses ultra-wideband technology to measure the distance between the devices. Based on this distance, the electronic device is controlled to be either locked or unlocked.

Methods for edge analytics in open radio access network
Patent published on the 2026-10-15 in WO under Ref WO2026217495 by MAVENIR SYSTEMS INC [US] (Taneja Mukesh [in], Kinnavy Michael [us])
Abstract: The present disclosure pertains to Open Radio Access Network (O-RAN) systems, addressing the technical challenge of managing increased uplink (UL) data traffic load over the backhaul and elevated control loop latency for applications such as video surveillance and IoT. The described method and system enable performing edge analytics at or near the Centralized Unit-User Plane (CU-UP). The UL Media Access Control (MAC) Protocol Data Units (PDUs) are processed through MAC, Radio Link Control (RLC),[...]
Our summary: The method enhances edge analytics in O-RAN systems by processing uplink data traffic at the CU-UP. It routes selected IP packets to a RAN Edge Compute node for analytics and re-encryption. This approach reduces backhaul traffic and supports low-latency applications like video surveillance and IoT.

Secure and verifiable coercion-resistant electronic exam
Published on 2026-08-27 by @OXFORD
Abstract: AbstractSince they enable efficient assessment of large cohorts of students and test-takers, electronic exams (e-exams) have become popular. However, the transition from pencil-and-paper tests to e-exams comes with challenges: researchers needed to ensure a comparable level of security and privacy as that enjoyed before the transition; at the same time, they have to address threats due to the use of information and communication technology. Research has shown that, for the reason of assessment f[...]
Our summary: This work addresses the challenges of coercion-resistance in electronic exams. A novel definition of coercion is proposed, revealing vulnerabilities in existing protocols. The improved protocol maintains essential security properties and is formally verified using ProVerif.

Enhancing grayscale image encryption through Petri net dynamics and hash-extracted keystreams
Published on 2026-07-08 by @OXFORD
Abstract: AbstractThe rapid advancement of digital communication underscores the necessity for secure image transmission. Traditional encryption methods often fall short in addressing the unique challenges posed by image data, such as high redundancy and interpixel correlations. This study introduces a novel Petri net-based encryption scheme for grayscale images, leveraging the deterministic evolution of Petri nets to generate high-entropy keystreams. By integrating the SHA-256 hash function, the scheme e[...]
Our summary: This study presents a Petri net-based encryption scheme for grayscale images that generates high-entropy keystreams. It utilizes the SHA-256 hash function to extract keystream bytes and enhances diffusion through a cipher-feedback mechanism. Evaluations show strong resistance to attacks and confirm the method s practicality and security.
