In the previous blog “The Many Flavors of AES – Part 2″, we “navigated” through the world of AES “modes” like ECB, CBC, OFB, CFB, CTR, CCM, GCM and XTS.
We will explore today a few of the selection points that need to be taken into account when looking for AES based solutions.
Selection point one: what security applications in what overarching application are you going to use AES for? Is it IPsec, SSL/TLS, Wi-Fi, MACsec, WiMAX, LTE-Advanced, Storage, etc? Knowing which application space for AES will usually tell you a lot about the modes, key size requirements, and throughput requirements. This helps narrow things down a lot for the next steps.
