WebMAC) for streaming-accessed chunks and fine-grain MAC (i.e., per block MAC) for random-accessed ones, to reduce the MAC access bandwidth. To support dual-granularity MACs, we reserve space for both MACs and access only one of them at runtime based on the access pattern. Our hardware scheme to detect streaming accessed chunks is shown in … Websecurity of E as a MAC, making it useless for answering Question 1. Second, even for the case of PRFs and ROs, where chopping a linear fraction of bits does preserve the corresponding property, one loses a lot in exact security, since the output is now much shorter. For example, dropping half of the bits would give a VIL-PRF with efﬁciency
