Abstract
A method is provided for transmitting encrypted packets from a first node to a second node of a communication network. The first node pads each plaintext packet with a respective padding content. The padded plaintext packets are then encrypted and transmitted to the second node. For each plaintext packet, the first node randomly selects the padding size in a range comprised between a minimum padding size and a maximum padding size. If the size of a plaintext packet is lower than a predefined minimum packet size, the minimum padding size is set equal to the difference between predefined minimum packet size and the plaintext packet size.
