Structural Approaches for Spn Analysis
Petri nets and Markovian Petri nets are excellent tools for logic and performability system modeling. However, the size of the underlying reachability set is a major limitation in practice. One approach gaining attention among researchers is the use of structured representations, which require us to decompose a net into, or compose a net from, subnets. This paper surveys the stateof-the-art in ...
متن کاملDrosophila oogenesis: Versatile spn doctors
Recent work on Drosophila oogenesis has uncovered connections between cell-cycle checkpoints and pattern formation. Genes of the spindle class, which encode double-strand break repair enzymes and RNA helicases, affect oocyte polarity and the decision whether to differentiate as an oocyte or a nurse cell.
متن کاملSCARE of Secret Ciphers with SPN Structures
Side-Channel Analysis (SCA) is commonly used to recover secret keys involved in the implementation of publicly known cryptographic algorithms. On the other hand, Side-Channel Analysis for Reverse Engineering (SCARE) considers an adversary who aims at recovering the secret design of some cryptographic algorithm from its implementation. Most of previously published SCARE attacks enable the recove...
متن کاملNew Insights on AES-Like SPN Ciphers
It has been proved in Eurocrypt 2016 by Sun et al. that if the details of the S-boxes are not exploited, an impossible differential and a zero-correlation linear hull can extend over at most 4 rounds of the AES. This paper concentrates on distinguishing properties of AES-like SPN ciphers by investigating the details of both the underlying S-boxes and the MDS matrices, and illustrates some new i...
متن کاملExpanders and the Affine Building of Spn
For n ≥ 2 and a local field K, let ∆n denote the affine building naturally associated to the symplectic group Spn(K). We compute the spectral radius of the subgraph Yn of ∆n induced by the special vertices in ∆n, from which it follows that Yn is an analogue of a family of expanders and is non-amenable.
