Strong Pseudorandompermutations or SPRPs,which were introduced byLuby andRacko? [4], formalize the well established cryptographic notion ofblock ciphers.They provided a construction of SPRP, well known as LRconstruction, which was motivated by the structure of DES[6].The basicbuildingblock is the so called 2n-bit Feistel permutation (or LR round permutation) LR based F K on an n-bitpseudorandomfunction (PRF) F : K n LR (x ,x)=(F (x )?x ,x ),x ,x?{0,1} . F 1 2 K 1 2 1 1 2 K Theirconstruction consists (see Fig 1) offour rounds of Feistel permutations (or three rounds, for PRP), each round involves an application ofanindependent PRF(i.e.with independentrandomkeys K ,K ,K , and K ). More precisely, 1 2 3 4 LR and LR are PRP and SPRP respectively where K ,K ,K K ,K ,K ,K 1 2 3 1 2 3 4 LR := LR := LR (...(LR (·))...). K ,...,K F ,...,F F F 1 r K K K K r r 1 1 After this work, many results are known improvingperformance (reducingthe number of invocations of F )[5] and reducingthekey-sizes (i.e. reusingthe K roundkeys [7,8,10,12,11] orgenerate more keysfromsinglekey by usinga PRF[2]). However there are some limitations.Forexample,wecannotuseas few as single-keyLR (unless wetweak the roundpermutation) orasfew as two-roundsince they are not secure.Distinguishing attacks forsome other LR constructionsarealso known [8]. We list some oftheknow related results (see Table 1). Here all keys K ,K ,... are independently chosen. Books<

The four-volume set, LNCS 12825, LNCS 12826, LNCS 12827, and LNCS 12828, constitutes the refereed proceedings of the 41st Annual International Cryptology Conference, CRYPTO 2021. Crypto has traditionally been held at UCSB every year, but due to the COVID-19 pandemic it was an online event in 2021.The 103 full papers presented in the proceedings were carefully reviewed and selected from a total of 426 submissions. The papers are organized in the following topical sections:Part I: Award Papers, Signatures, Quantum Cryptography, Succinct Arguments.Part II: Multi-Party Computation, Lattice Cryptography, and Lattice Cryptanalysis.Part III: Models, Applied Cryptography and Side Channels, Cryptanalysis, Codes and Extractors, Secret Sharing.Part IV: Zero Knowledge, Encryption++, Foundations, Low-Complexity Cryptography, Protocols.
