One disclosed example method includes obtaining a meeting cryptographic key; transmitting, from a client device to a video conference provider, a request to initiate an encrypted video conference, the encrypted video conference including a plurality of participants; distributing the meeting cryptographic key to each participant of the plurality of participants; obtaining a public cryptographic key of a key pair, the key pair including the public cryptographic key and a private cryptographic key; encrypting the meeting cryptographic key using the public cryptographic key; transmitting, from the client device to the video conference provider, a request to record the video conference; encrypting audio and video from a microphone and image sensor of the client device using the meeting cryptographic key; transmitting the encrypted audio and video to the video conference provider; and providing the encrypted meeting cryptographic key to the video conference provider.

An apparatus to facilitate transparent network access controls for spatial accelerator device multi-tenancy is disclosed. The apparatus includes a secure device manager (SDM) to: establish a network-on-chip (NoC) communication path in the apparatus, the NoC communication path comprising a plurality of NoC nodes for ingress and egress of communications on the NoC communication path; for each NoC node of the NoC communication path, configure a programmable register of the NoC node to indicate a node group that the NoC node is assigned, the node group corresponding to a persona configured on the apparatus; determine whether a prefix of received data at the NoC node matches the node group indicated by the programmable register of the NoC; and responsive to determining that the prefix does not match the node group, discard the data from the NoC node.

Embodiments of the present invention provide a system for utilizing one or more decentralized applications to allow entities to interface with a blockchain for the purposes of conducting a resource transfer. Typically, the blockchain is a permissioned blockchain which may be accessed only by the entities involved in the resource transfer. The decentralized applications may communicate with the legacy systems within each entity through an application programming interface (API) such that the data stored on the legacy systems may be governed by the blockchain. This ensures the authenticity of the data stored on the legacy systems while preventing the possibility of disparate versions of data being created over time.

Methods, apparatus, systems, and articles of manufacture are disclosed to protect distributed data. An example apparatus includes at least one memory, machine readable instructions, and processor circuitry to at least one of instantiate or execute the machine readable instructions to detect a key identifier combination from a distributed key, identify a match between the key identifier combination and a platform identifier combination, extract a second key from the distributed key, the second key associated with the object, and decrypt the object via the extracted second key.

Embodiments are directed to monitoring communication between computers using network monitoring computers (NMCs). NMCs identify a secure communication session established between two of the computers based on an exchange of handshake information associated with the secure communication session. Key information that corresponds to the secure communication session may be obtained from a key provider such that the key information may be encrypted by the key provider. NMCs may decrypt the key information. NMCs may derive the session key based on the decrypted key information and the handshake information. NMCs may decrypt network packets included in the secure communication session. NMCs may be employed to inspect the one or more decrypted network packets to execute one or more rule-based policies.

An improved telecommunications network that can reduce the network load on a rich communication services (RCS) server and/or local routers that implement 1-to-N and/or M-to-N services is described herein. In particular, the improved telecommunications network may include an improved RCS server that can route secure multicast messages instead of and/or in addition to unicast messages. For example, the improved RCS server can create a multicast group for a group of UEs in response to a request from a UE to create a group of UEs. Creation of the multicast group may include creating a shared multicast group key (SMGK) for the multicast group and/or selecting a security algorithm for the multicast group. The improved RCS server can then distribute the SMGK and/or the selected security algorithm to the UEs such that the UEs can use the SMGK and/or the selected security algorithm to encrypt and/or decrypt messages.

Cryptographically secure data communications between layered groups of devices in a wireless cooperative broadcast network encrypts datagrams twice prior to transmission by a source device, first using an inner layer key that is shared by a first group of devices, and second using an outer layer key that is shared by a second group of devices; the devices of the first group being members of the second group. Received datagrams are recovered by first decrypting with the outer layer key and second decrypting with the inner layer key.
