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)
The Lai–Massey scheme is a cryptographic structure used in the design of block ciphers. It is used in IDEA and IDEA NXT. The scheme was originally introduced by Xuejia Lai with the assistance of James L. Massey, hence the scheme's name, Lai-Massey. Web11 de jun. de 2024 · In the case of Lai–Massey schemes, where both Substitution Permutation Network and Feistel Network features are combined, the resistance against imprimitivity attacks has been a long-standing open problem. In this paper we consider a generalization of such a scheme and we prove its resistance against the imprimitivity …
