Proving the Security of the Extended Summation-Truncation Hybrid
Abstract
Since designing a dedicated secure symmetric PRF is difficult, various works studied optimally secure PRFs from the sum of independent permutations (SoP).
At CRYPTO'20, Gunsing and Mennink proposed the Summation-Truncation Hybrid (STH).
While based on SoP, STH releases additional
