Adding AES-ICM and AES-GCM to OpenCrypto

by John-Mark Gurney

Adding additional cipher modes may seem simple, but there are many things to consider.

Implementing the modes and ensuring security requires more than a simply coding it up. It requires understanding of different standards and computer architecture to make sure things like side channel/timing attacks are addressed or properly understood. Some design decisions can be made to help ensure that consumers of the interface are able to properly use it.
