Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.

Abstract: Technologies for key management of internet-of-things (IoT) devices include an IoT device, an authority center server, and a group management server. The IoT device is configured to authenticate with an authority center server via an offline communication channel, receive a group member private key as a function of the authentication with the authority center server, and authenticate with a group management server via a secure online communication channel using the group member private key. The IoT device is further configured to receive a group shared key as a function of the authentication with the group management server, encrypt secret data with the group shared key, and transmit the encrypted secret data to the group management server. Other embodiments are described herein.

Abstract: Examples relate to apparatuses, devices, methods and computer programs for modifying a target application. An apparatus for a computer system comprises memory circuitry, machine-readable instructions, and processor circuitry to execute the machine-readable instructions to launch, using a loader application, a target application, obtain, by the loader application, information on a kernel system call having been made by the target application, and modify, by the loader application and based on the information on the kernel system call having been made by the target application, an instruction of the target application, wherein the modified instruction is configured to trigger an operation being equivalent to the kernel system call, with the operation being equivalent to the kernel system call while avoiding a context switch.

Abstract: Examples described herein relate to a switch comprising a programmable data plane pipeline, wherein the programmable data plane pipeline is configured to provide microservice-to-microservice communications within a service mesh. In some examples, to provide microservice-to-microservice communications within a service mesh, the programmable data plane pipeline is to perform a forwarding operation for a communication from a first microservice to a second microservice. In some examples, to perform a forwarding operation for a communication from a first microservice to a second microservice, the programmable data plane pipeline is to utilize a reliable transport protocol.

Abstract: In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.

Abstract: A cryptographic data item utilized to derive a first cryptographic key employed by a first memory controller for implementing a first cryptographically protected execution environment for storing memory pages associated with a virtual machine may be received from a first host system via a first secure communication channel. The cryptographic data item may be transmitted to a second host system via a second secure communication channel for implementing a second cryptographically protected environment on the second host system. The first host system may be caused to migrate the memory pages of the virtual machine via an unsecured communication channel to the second host system for storing in the second cryptographically protected execution environment.
