Embodiments of the present disclosure relate to a method for encryption and decryption, a programmable switch, and a computer program product. The method comprises receiving, at a programmable switch, encrypted data to be sent to a certain Internet of Things (IoT) device, wherein the encrypted data is encrypted using a public key of the programmable switch. The method further comprises decrypting the encrypted data using a private key of the programmable switch to obtain decrypted data, and then sending the decrypted data from the programmable switch to the IoT device. According to the embodiments of the present disclosure, the encryption and decryption operations of the IoT device can be transferred to the programmable switch for processing, and the programmable switch is used to help the IoT device perform encryption and decryption.

Method for encryption and decryption, programmable switch and computer program product

Embodiments of the present disclosure relate to a method, a device, and a computer program product for data processing. The method comprises determining information associated with an attribute of a data packet from a source device; determining, based on the information, a target operation to be performed on the data packet; performing the target operation on the data packet; and causing the data packet on which the target operation has been performed to be sent to a target device of the data packet. In this manner, by using advantages of programmable switches, encapsulation and decapsulation operations are introduced for communications between edge Internet of Things network devices and data center applications, which can significantly increase the throughput.

Method, electronic device, and computer program product for data processing

In illustrative embodiments, an information processing method, an electronic device, and a computer-readable storage medium are provided. The method includes: if it is determined that a predetermined indicator is detected in a header of a received packet, acquiring information for indicating a source port, a destination port, a forwarding indicator, a process identifier, and a maximum number of processes of the packet from the header; updating a port forwarding table based on the source port, the destination port, and the forwarding indicator; performing a user-defined action on the packet to obtain a result packet; and if it is determined that a quantity of process identifiers reaches the maximum number of processes, determining one or more forwarding ports for the result packet based on the maximum number of processes, the forwarding indicator, and the updated port forwarding table, to forward the result packet to the one or more forwarding ports.

Information processing method, electronic device and computer storage medium

A method, an electronic device, and a computer-readable storage medium for information processing are provided according to example embodiments of the present disclosure. The method comprises receiving, at a storage device, a data block and fingerprint information correlated with the data block, the fingerprint information being configured to identify the data block; and determining a storage position of the received data block based on predetermined correlations between fingerprint information and storage positions and the received fingerprint information, the predetermined correlations comprising at least correlations between historical fingerprint information correlated with stored data blocks and historical storage positions. Thus, a storage position of a data block can be determined based on received fingerprint information and predetermined correlations between fingerprint information and storage positions, thereby improving efficiency of redundant data deletion.
