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

A programmable switch, comprising:

• a processing unit;
• and
• a memory coupled to the processing unit and storing instructions that, when executed by the processing unit, perform the following actions:
• receiving encrypted data directed to an Internet of Things (IoT) device, the encrypted data being encrypted using a public key of the programmable switch;
• decrypting the encrypted data using a private key of the programmable switch to obtain decrypted data;
• and
• sending the decrypted data to the IoT device.

A computer program product that is tangibly stored on a non-transitory computer-readable medium and contains computer-executable instructions that, when executed, cause a computer to implement a method for encryption and decryption, comprising:

• receiving, at a programmable switch, encrypted data directed to an Internet of Things (IoT) device, the encrypted data being encrypted using a public key of the programmable switch;
• decrypting the encrypted data using a private key of the programmable switch to obtain decrypted data;
• and
• sending the decrypted data from the programmable switch to the IoT device.
