Embodiments of communication systems are disclosed for protecting communication between an implanted device ID and an external device ED. For example, a one way Transcutaneous energy transfer TET link may be used to secure two way communication over a radio channel. Optionally, the TET link may be protected from intrusion by a malicious party. For example, the TET link may be over a medium that decays very quickly over distance. In some embodiments, the TET link is used to pass an encryption key and/or to verify communications over the two-way radio channel. The TET channel may be authenticated. For example, authentication may include a minimum energy and/or power transfer.

A data packet transits through a series of network nodes (a series of intermediate hops) while being transmitted from a source node to a destination node. A network node (router, gateway, server, or any network device) that handles the data packet, adds new information to the file header of the data packet. The new header information identifies the previous and next network nodes in the transmission path. The network node further validates information provided by a previous node, and generates further new header information that attests as to the validity of the information provided by the previous node. The network node secures and signs the new information cryptographically, and adds the new information to the file header. If a malicious actor attempts to tamper with the data packet, or routing thereof, the secured header information renders such tampering discoverable, enabling performance of a responsive action.

A network communications method utilizing a network watermark for providing security in the communications includes creating a verifiable network communications path of nodes through a network for the transfer of information from a first end node to a second end node; verifying the network communications path of nodes, by the first end node, before communicating by the first end node information intended for receipt by the second end node; and once the network communications path of nodes is verified by the first end node, communicating by the first end node, via the verified communications path of nodes, the information intended for receipt by the second end node; wherein the network watermark represents the verifiable network communications path of nodes.

A method for establishing a fully private, information secure interconnection between a source and a destination over a data network with at least a portion of a public infrastructure. The method comprising at the source creating n shares of a source data according to a predetermined secret sharing scheme, and encrypting the n shares using (n, k) secret sharing. Further, defining for at least one node vi a directed edge (Vi1, Vi2) that has a k−1 capacity. All outgoing links of vi are connected to vi2. Additionally, using a maximum flow algorithm to define the maximum number of shares outgoing from vi2, and therefore from vi, on each outgoing link. The number of shares forwarded by node vi does not exceed the number of maximum shares that were defined by the maximum flow algorithm.

Systems, methods, apparatuses, and computer program products for dynamically updating routing identifiers (IDs) are provided. One method may include deciding, at a network node, to update a routing identifier for at least one user equipment. The method may then include obtaining or generating a new routing identifier to be assigned to the at least one user equipment along with authentication vectors, and transmitting the new routing identifier to an authentication entity.

An electronic device and a control method thereof are provided. The electronic device includes an Internet protocol (IP) address corresponding to a domain name of a web page when a user command inputting the domain name is received, identifies a number of hops included in a network path connecting a server corresponding to the obtained IP address and the electronic device to each other, and determines that a man-in-the-middle attack exists in a network when a communication connection with the server is established on the basis of a smaller number of hops than the identified number of hops.

A method of user equipment (UE) implemented network slice security protection is disclosed. The method comprises the UE receiving a request to initialize an application, querying a UE Route Selection Policy (URSP) stored on the UE, and receiving traffic descriptors and security descriptors in response to the querying. The traffic descriptors identify a network slice for the application. The security descriptors comprise a security flag and a virtualization container ID. The method also comprises the UE initiating the application within a virtualization container corresponding to the virtualization container ID based on the security flag indicating that the network slice is secure and binding traffic for the application in the virtualization container to a PDU session based on the traffic descriptors. The method further comprises communicating, by the application executing within the virtualization container, with a core network over the PDU session via the network slice bound to the virtualization container.
