A quite unique feature of wolfBoot is the possibility to update the firmware using signed incremental updates. The mechanism relies on a delta algorithm that produces a small update package. Instead of transferring the entire binary image of the firmware update, incremental updates only contain the binary difference with the previous version. Distributing a new […]

What is a Block Cipher?
A block cipher is an encryption method that applies a deterministic algorithm along with a symmetric key to encrypt a block of text, rather than encrypting one bit at a time as in stream ciphers. For example, a common block cipher, AES (Advanced Encryption Standard), encrypts 128 bit blocks with a key of predetermined length: […]
