With the growing appreciation of RNA splicing's role in gene regulation, development, and disease, researchers from diverse fields find themselves investigating exons of interest. Commonly, researchers are interested in knowing if an exon is alternatively spliced, if it is differentially included in specific tissues or in developmental stages, and what regulatory elements control its inclusion....

In this paper, a formal analysis of security protocols in the field of wireless sensor networks is presented. Three complementary protocols, TinySec, LEAP and TinyPK, are modelled using the high-level formal language HLPSL, and verified using the model checking tool AVISPA, where two main security properties are checked: authenticity and confidentiality of messages. As a result of this analysis...

Recently, Farasha et al. proposed an efficient user authentication and key agreement scheme for heterogeneous wireless sensor network tailored for the Internet of Things environment. By using BAN-logic and AVISPA tools, they confirm the security properties of the proposed scheme. However, after analyzing, we determine that the scheme could not resist the smart card loss password guessing attack...

The verification of cryptographic protocols has greatly improved these last years. Automated tools such as AVISPA provide real help in finding and characterizing attacks. The counterpart is the formal specification of the protocol, using an appropriate language such as HLPSL. Since HLPSL is a very expressive language, this stage is complicated and error-prone before a correct specification is e...

Security protocols are often specified at the application layer ; however, application layer specifications give little detail regarding message data structures at the presentation layer upon which some implementation-dependent attacks rely. In this paper we present an approach to verifying security protocols in which both the application and presentation layers are modelled. Using the Group Do...

In this paper we consider the problem of verifying time–sensitive security protocols, where temporal aspects explicitly appear in the description. In previous work, we proposed Timed HLPSL, an extension of the specification language HLPSL (originally developed in the Avispa Project), where quantitative temporal aspects of security protocols can be specified. In this work, a model checking tool,...

CASPA constitutes a push-button tool for automatically proving secrecy and authenticity properties of cryptographic protocols. The tool is grounded on a novel technique for causality-based abstraction of protocol executions that allows establishing proofs of security for an unbounded number of concurrent protocol executions in an automated manner. We demonstrate the expressiveness and efficienc...

We present an algorithm for the translation of security protocol specifications in the HLPSL language developed in the framework of the AVISPA project to a dialect of the applied pi calculus. This algorithm provides us with two interesting scientific contributions: at first, it provides an independent semantics of the HLPSL specification language and, second, makes it possible to verify protoco...
