Abstract:

We present a new, provably secure, self-synchronizing authenticated encryption mode of operation, SLC, with the ability to re-synchronize after loss of transmission units of sub-block size, enabling it to efficiently handle short packets. The new scheme uses two components, self-synchronizing MAC and self-synchronizing encryption scheme, each of which is individually interesting. The SLC mode, as well as both its components, are highly parallelizable and efficient in fault-tolerant applications.
