automatic verification of authentication protocols using genetic programming
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
15 صفحه اولAlgebraic Coding of Expansive Group Automorphisms and Two–Sided Beta–Shifts
Let α be an expansive automorphisms of compact connected abelian group X whose dual group X̂ is cyclic w.r.t. α (i.e. X̂ is generated by {χ · α : n ∈ Z} for some χ ∈ X̂). Then there exists a canonical group homomorphism ξ from the space `∞(Z,Z) of all bounded two-sided sequences of integers onto X such that ξ · σ = α · ξ, where σ is the shift on `∞(Z,Z). We prove that there exists a sofic subshift...
متن کاملSome properties of marginal automorphisms of groups
AbstractLet W be a non-empty subset of a free group. The automorphism of a group G is said to be a marginal automorphism, if for all x in G,x^−1alpha(x) in W^*(G), where W^*(G) is the marginal subgroup of G.In this paper, we give necessary and sufficient condition for a purelynon-abelian p-group G, such that the set of all marginal automorphismsof G forms an elementary abelian p-group.

متن کاملScale-dependent automatic shifts in brand evaluation standards
Different schema-based expectations for competing brands can produce shifting evaluative standards in consumers' relative ratings of these brands. This shift in standards differentially affects objective (number-based) and subjective (word-based) rating scales. Several studies support the proposition that a brand rated as objectively inferior to another can be subjectively perceived as equivale...
