Proving Security Goals With Shape Analysis Sentences [article]

John D. Ramsdell
2014 arXiv   pre-print
The result is a semantically rich environment in which the validity of a security goal can be determined using shape analysis sentences and the foundation on which they are based.  ...  The paper that introduced shape analysis sentences presented a method for extracting a sentence in first-order logic that completely characterizes a run of CPSA.  ...  Given a shape analysis sentence, a security goal is achieved if the goal can be deduced from the sentence. cpsa includes a Prolog program that translates shape analysis sentences into Prover9 [11] syntax  ...

Deducing Security Goals From Shape Analysis Sentences [article]

John D. Ramsdell
2018 arXiv   pre-print
Guttman presented a model-theoretic approach to establishing security goals in the context of Strand Space theory.  ...  In his approach, a run of the Cryptographic Protocol Shapes Analyzer (CPSA) produces models that determine if a goal is satisfied.  ...  Using Horn clauses for analyzing security protocols.  ...

A Hybrid Analysis for Security Protocols with State [article]

John D. Ramsdell, Daniel J. Dougherty, Joshua D. Guttman, Paul D. Rowe
2014 arXiv   pre-print
We define a hybrid analysis method. It leverages theorem-proving---in this instance, the PVS prover---for reasoning about computations over state.  ...  It combines that with an "enrich-by-need" approach---embodied by CPSA---that focuses on the message-passing part. As a case study we give a full analysis of the Envelope Protocol, due to Mark Ryan.  ...  A sentence, called a shape analysis sentence [22, 15] , summarizes its results in a sentence in the language Figure 1 : Theory Inclusions of T bnd (Π).  ...

Homomorphisms and Minimality for Enrich-by-Need Security Analysis [article]

Daniel J. Dougherty and Joshua D. Guttman and John D. Ramsdell
2018 arXiv   pre-print
LPA uses two programs, cooperating with each other: CPSA, a well-known system for protocol analysis, and Razor, a model-finder based on SMT technology.  ...  Our analysis follows the enrich-by-need paradigm, in which models of protocol execution are generated and examined.  ...  We regard the shape analysis as a security goal achieved by G ∪ T h(Π). Thus, finding a finite set of finite shapes determines a strongest security goal that the system achieves.  ...

Damaska and the Faces of International Criminal Justice

B. Swart
2008 Journal of International Criminal Justice  
Goals of a conflict-solving nature are best served by a legal process structured as a contest between two parties  ...  Consequently, all proceedings take the shape of a contest between two parties. In the reactive state, on the other hand, all law is an expression of state policies.  ...  Sentencing goals might well have stronger procedural consequences for the shape of separate sentencing proceedings, resulting in separate sentencing judgments.  ...

An empirical study on the use of the Generic Security Template for structuring the lessons from information security incidents

Ying He, Chris Johnson, Karen Renaud, Yu Lu, Salem Jebriel
2014 2014 6th International Conference on Computer Science and Information Technology (CSIT)  
Moreover, this paper has empirically evaluated this approach to the creation of a Generic Security Template; this provides users with an overview of the lessons derived from security incidents at a level  ...  In particular, it adapts the graphical Goal Structuring Notation (GSN), to present lessons learned in a structured manner by mapping them to the security requirements of the ISMS.  ...  to its relationships with the goals.  ...

Security Theorems via Model Theory

Joshua Guttman
2009 Electronic Proceedings in Theoretical Computer Science  
Hence, to verify a security goal, one can use the Cryptographic Protocol Shapes Analyzer CPSA (TACAS, 2007) to identify minimal realized skeletons, or "shapes," that are homomorphic images of A_phi.  ...  If psi holds in each of these shapes, then the goal holds.  ...  A sentence ∀ x . (φ ⊃ ∃ y . ψ) is a security goal if (1) the xs and ys are disjoint; (2) φ is a security claim; and (3) ψ is a disjunction i φ i of conjunctions φ i of atomic formulas.  ...

Auditing User-Provided Axioms in Software Verification Conditions [chapter]

Paul Jackson, Florian Schanda, Angela Wallenburg
2013 Lecture Notes in Computer Science  
Such axioms can also describe properties of constants, functions and relations that are introduced to help with program specification.  ...  Prover-hint axioms address incompletenesses in automatic provers, their failure to prove VCs that are logically valid.  ...  The results obtained with main approaches are dependent on the theorem proving power of the selected prover.  ...

The role of innovation and wealth in the net neutrality debate: A content analysis of human values in congressional and FCC hearings

An-Shou Cheng, Kenneth R. Fleischmann, Ping Wang, Emi Ishita, Douglas W. Oard
2012 Journal of the American Society for Information Science and Technology  
We examine the role of human values in shaping the Net neutrality debate through a content analysis of testimonies from U.S. Senate and FCC hearings on Net neutrality.  ...  The analysis is based on a coding scheme that we developed based on a pilot study in which we used the Schwartz Value Inventory.  ...  The unit of analysis was the sentence, although we interpreted each sentence within its context within the document.  ...
