  • Publication number: 20240137760
    Abstract: A device and method and computer readable medium for resisting downgrade attacks. User equipment includes a memory having instructions stored thereon and a processor configured to execute the instructions stored on the memory to cause the user equipment to perform the following operations: determining a security authentication type when the user equipment is connected to a network device for the first time; and in response to determining that the security authentication type when the user equipment is connected to the network device for the first time is WPA3, applying the only-WPA3 rule; where the only-WPA3 rule only allows the user equipment to use WPA3 to access the network device, and refuses the user equipment to use other security authentication types with lower security than WPA3 to access the network device.

  • Patent number: 11438305
    Abstract: The disclosure relates to methods, routers, media and apparatus for implementing enhanced UPnP subscriptions. According to an embodiment of the disclosure, there is provided a method for implementing an enhanced UPnP subscription, comprising, by a UPnP-enabled router: receiving a subscription message for a subscription, wherein the subscription message specifies a delivery uniform resource locator (URL), the delivery URL is a location where an event message targeted by the subscription is to be sent; checking, based on a whitelist, whether an IP address or a domain name in the delivery URL is contained in the whitelist; and determining whether to reject the subscription message based on the checking result. Through embodiments of the disclosure, both flexible subscription and high security can be achieved.
