What is an IPv6 address? An IPv6 address is a 128-bit numerical address that is assigned to a network interface or a set of network interfaces. When a network packet in an IPv6 network contains an IPv6 address as the destination address, the network packet is...
In this article, we would implement the Diffie-Hellman Key Exchange algorithm in Python. In the last article, we explained how to implement the Diffie-Hellman Key Exchange algorithm using the pyDHE Python library. But, in this article, we would not use any Python...
What is an Ethernet frame? An Ethernet frame is the Protocol Data Unit of the data link layer of the OSI model. The data link layer of one device exchanges Ethernet frames with the data link layer of the other device. An Ethernet frame contains useful information like...
If we are using a block cipher, then we should select one block cipher mode of operation. These block cipher modes of operation provide better security. In a block cipher, the input plaintext is divided into several equal-sized blocks and the last block is padded....
There are a number of Python modules using which we can perform AES encryption and decryption. But, in this article, we would try to implement the AES algorithm in a very simple and easy-to-understand way. AES is a block cipher. The input plaintext is divided into...
