Web18 de jan. de 2007 · In this paper we investigate the Lai-Massey scheme which was used in IDEA. We show that we cannot use it  as is in order to obtain results like the Luby-Rackoff theorem. This can however be done by introducing a simple function which has an orthomorphism property.

Web3 de nov. de 2024 · We introduce here our algebraic description of the Lai-Massey scheme [ LM91] as presented by Vaudenay [ Vau99]. Definition 2.5. Let r be a non-negative integer, ρ∈Sym(V)∖AGL(V) and π∈GL(V) . An r -round Lai-Massey cipher LM(ρ,π) is a set of encryption functions {EK∣K∈K}⊆Sym(V ×V) Web19 de set. de 2024 · In this paper, we re-investigate the Lai-Massey scheme, originally proposed in the cipher IDEA.

WebFeistel scheme is also used for construction of S-boxes of the symmetric ciphers CS [13], CRYP-TON [7] and ZUC [14]. For another example, the FI function of the block cipher MISTY [8] is based upon the Feistel scheme. The Lai-Massey scheme was used for the rst time in 1990 in the design of PES (Proposed Encryption Standard) [6] by Lai and Massey. WebON THE PRIMITIVITY OF LAI-MASSEY SCHEMES 3 2.1.2. Groups.
