Understanding AES Encryption Modes: From ECB to CBC and CTR
In previous posts, we discussed how AES encryption works, breaking down the process of encrypting a 128-bit (16-byte) plaintext into a ciphertext of the same […]
Wi-Fi Roaming and OpenRoaming: Technologies and Standards
The term “roaming” is widely used to describe the process of switching between Access Points. In this context, an STA (Station) associated with AP-A transitions […]
Understanding AES Key Expansion
This post explains how the key expansion process works for AES-128, AES-192, and AES-256. To review some fundamentals: AES is an encryption standard that encrypts […]
