On ZpZp[u, v]-additive cyclic and constacyclic codes
Let be the ring of residue classes modulo a prime . The
-additive cyclic codes of length
is identify as -submodule of
where
with
. In this article, we obtain the complete sets of
generator polynomials, minimal generating sets for cyclic codes with length
over and
-additive cyclic codes with length
respectively. We show that the Gray image of
-additive cyclic code with length
is either a QC code of length with index or a
generalized QC code of length over .
Moreover, some structural properties like generating polynomials, minimal
generating sets of -additive constacyclic
code with length are determined.Comment: It is submitted to the journa
An anti-malware product test orchestration solution for multiple pluggable environments
The term automation gets thrown around a lot these days in the software industry. However, the recent change in test automation in the software engineering process is driven by multiple factors such as environmental factors, both external and internal as well as industry-driven factors. Simply, what we all understand about automation is - the use of some technologies to operate a task. The choice of the right tools, be it in-house or any third-party software, can increase effectiveness, efficiency and coverage of the security product testing.
Often, test environments are maintained at various stages in the testing process. Developer’s test, dedicated test, integration test and pre-production or business readiness test are some common phrases in software testing. On the other hand, abstraction is often included between different architectural layers, ever-changing providers of virtualization platforms such as VMWare, OpenStack, AWS as test execution environments and many others with a different state of maintainability. As there is an obvious mismatch in configuration between development, testing and production environment; software testing process is often slow and tedious for many organizations due to the lack of collaboration between IT Operations and Software Development teams. Because of this, identifying and addressing test environmentrelated compatibility becomes a major concern for QA teams.
In this context, this thesis presents a DevOps approach and implementation method of an automated test execution solution named OneTA that can interact with multiple test environments including isolated malware test environments. The study was performed to identify a common way of preparing test environments in in-house and publicly available virtualization platforms where distributed tests can run on a regular basis. The current solution allows security product testing in multiple pluggable environments in a single setup utilizing the modern DevOps practice to result minimum efforts.
This thesis project was carried out in collaboration with F-Secure, a leading cyber security company in Finland. The project deals with the company’s internal environments for test execution. It explores the available infrastructures so that software development team can use this solution as a test execution tool
New Quantum and LCD Codes over Finite Fields of Even Characteristic
For an integer m ≥ 1, we study cyclic codes of length l over a commutative non-chain ring F2m + uF2m , where u2 = u . With a new Gray map and Euclidean dual-containing cyclic codes, we provide many new and superior codes to the best-known quantum error-correcting codes. Also, we characterise LCD codes of length l with respect to their generator polynomials and prove that F2m − image of an LCD code of length l is an LCD code of length 2l . Finally, we provide several optimal LCD codes from the Gray images of LCD codes over F2m + uF2m .
 
Constacyclic codes of length over the Galois ring
For prime , represents the Galois ring of order and
characterise , where is any positive integer. In this article, we study
the Type (1) -constacyclic codes of length over the ring
, where , are
nonzero elements and . In first case, when is a
square, we show that any ideal of

and
. In second, when
is not a square, we show that is a chain
ring whose ideals are , for where .
Also, we prove the dual of the above code is and
present the necessary and sufficient condition for these codes to be
self-orthogonal and self-dual, respectively. Moreover, the Rosenbloom-Tsfasman
(RT) distance, Hamming distance and weight distribution of Type (1)
-constacyclic codes of length are obtained when is
not a square.Comment: This article has 18 pages and ready to submit in a journa
