    Automatic proof of resistance of denial of service attacks in protocols by Bo MENG, Wei HUANG, De-jun WAND, Fei SHAO

    Published 2012-03-01
    “…First,the applied PI calculus was extended from two aspects:attacker contexts and process expression,then from the view of protocol state,the protocols were modeled with the extended applied PI calculus and a automatic method of proof of resistance of denial of service attacks based on theorem proof with first order theorem prover ProVerif was presented,finally resistance of denial of service attacks in JFK protocol and IEEE 802.11 four-way handshake protocol were analyzed.The results obtained are that JFK protocol is resistance of denial of service attack and IEEE 802.11 four-way handshake protocol is not.At the same time a new al of service attack in IEEE 802.11 four-way handshake protocol was found.The methods to prevent resistance of denial of service attacks in IEEE 802.11 four-way handshake protocol were proposed.…”

    Continuité des racines d’après Rabinoff by Marie, Emeryck

    Published 2023-03-01
    “…The content of this paper is a generalization of a theorem by Joseph Rabinoff: if $\mathscr{P}$ is a finite family of pointed and rational polyhedra in $N_\mathbb{R}$ such that there exists a fan in $N_\mathbb{R}$ that contains all the recession cones of the polyhedra of $\mathscr{P}$, if $k$ is a complete non-archimedean field, if $S$ is a connected and regular $k$-analytic space (in the sense of Berkovich) and $Y$ is a closed $k$-analytic subset of $U_{\mathscr{P}} \times _k S$ which is relative complete intersection and contained in the relative interior of $U_{\mathscr{P}} \times _k S$ over $S$, then the quasifiniteness of $\pi : Y \rightarrow S$ implies its flatness and finiteness; moreover, all the finite fibers of $\pi $ have the same length. …”
