Publication number: 20230370245Abstract: Described systems and methods allow carrying out privacy-preserving DNS exchanges. In some embodiments, a client machine engages in a private information retrieval (PIR) exchange with a nameserver. In response to receiving an encrypted query from the client, the query formulated according to a domain name, the nameserver may extract a record (e.g., an IP address) from a domain name database without decrypting the respective query. Some embodiments achieve such information retrieval by the use of homomorphic encryption.Type: ApplicationFiled: July 24, 2023Publication date: November 16, 2023Inventors: Bogdan C. CEBERE, Elena BURCEANU, Madalina BOLBOCEANU, Emanuela HALLER, Georgiana M. ROSCA, Radu TITIU

Patent number: 11706051Abstract: In some embodiments, a network regulator device protects a local network of client systems (e.g. Internet-of-things devices such as smartphones, home appliances, wearables, etc.) against computer security threats. When introduced to the local network, some embodiments of network regulator take over some network services from a router, and automatically install the network regulator as gateway to the local network. The network regulator then carries out an automatic device discovery procedure and distribute device-specific utility agents to the protected client systems. An exemplary utility agent detects when its host device has left the local network, and in response, sets up a virtual private network (VPN) tunnel with a security server to maintain protection of the respective device.Type: GrantFiled: September 17, 2018Date of Patent: July 18, 2023Assignee: Bitdefender IPR Management Ltd.Inventors: Cosmin C. Stan, Andrei Rusu, Bogdan C. Cebere, Alexandru I. Achim

Patent number: 10644949Abstract: Described systems and methods enable an automatic device detection/discovery, particularly of ‘Internet of Things’ client devices such as wearables, mobile communication devices, and smart home appliances, among others. Device detection comprises assigning a target device to a device category, such as “tablet computer from an unknown manufacturer, running Android®”. Some embodiments determine multiple preliminary category assignments according to distinct inputs such as HTTP user agent data, DHCP data, mDNS data, and MAC data. Each preliminary category assignment may come with an associated score. A definitive category assignment may be made according to an aggregate score. Applications include computer security, software provisioning, and remote device management, among others.Type: GrantFiled: March 29, 2017Date of Patent: May 5, 2020Assignee: Bitdefender IPR Management Ltd.Inventor: Bogdan C.

Patent number: 10375572Abstract: In some embodiments, a network regulator device protects a local network of client systems (e.g. Internet-of-things devices such as smartphones, home appliances, wearables, etc.) against computer security threats. Various aspects of the operation of the network regulator may be managed remotely via a graphical user interface (GUI) executing on an administration device, such as a mobile phone. The GUI is further configured to display a security notification to a user of the administration device, the security notification indicating the occurrence of a security event caused by an action of a protected client system.Type: GrantFiled: December 11, 2015Date of Patent: August 6, 2019Assignee: Bitdefender IPR Management Ltd.Inventors: Alexandru I.
