Abstract
A technology is described for applying authentication on a constrained bandwidth link. The method may determine an amortization factor for authentication to be applied to data blocks sent across the constrained bandwidth link. The amortization factor may be pre-set or received from a user during a communication session. Another operation may be generating truncated authentication codes that are keyed cryptographic checksums for the data blocks. A truncation size of the truncated authentication codes may be defined in part by the amortization factor. The data blocks may be sent across the constrained bandwidth link with the truncated authentication codes to the receiving node.
