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 … WebOn the Adaptive Security of MACs and PRFs.

On the Adaptive Security of MACs and PRFs
Web1 de jan. de 2024 · Abstract. A compression-function-based MAC function called FMAC was presented as well as a vector-input PRF called vFMAC in 2016. They were proven to be secure PRFs on the assumption that their ... Web3 de dez. de 2000 · It is argued that it is possible to get better concrete security bounds for certain PRF/PRP-based schemes through using an alternate characterization of a PRF, and some insight is provided into how injectivity impacts pseudorandomness. We investigate several alternate characterizations of pseudorandom functions (PRFs) and … Web6 de dez. de 2024 · We consider the security of two of the most commonly used cryptographic primitives—message authentication codes (MACs) and pseudorandom … how do i add skyblock addons to forge
