This study aims to enhance the core competitiveness of enterprises in the competitive environment and realise the rapid and sound development of enterprise security. The relationship between the digital transformation of the supply chain and the core competitiveness of enterprises is discussed from the perspective of constructing the information security (IS) of the internet of things (IoT). Firstly, the ciphertext-policy attribute-based encryption (CP-ABE) model of the information centre is established to study the technical problems of information encryption of IoT enterprises. Secondly, the correlation analysis method is used to determine the impact of supply chain transformation on the future development of enterprises through the correlation between the digital transformation of the supply chain and enterprise competitiveness. Finally, targeted solutions are proposed for the digital transformation of the supply chain and the IS of IoT of enterprises.

SUMMARY: SScore is an R package that facilitates the comparison of gene expression between Affymetrix GeneChips using the S-score algorithm. The S-score algorithm uses probe level data directly to assess differences in gene expression, without requiring a preliminary separate step of probe set expression summary estimation. Therefore, the algorithm avoids introduction of error associated with the expression summary estimation process and has been demonstrated to improve the accuracy of identifying differentially expressed genes. The S-score produces accurate results even when few or no replicates are available. AVAILABILITY: The R package SScore is available from Bioconductor at http://www.bioconductor.org
