The aim of the work: to analyze the influence of the standard protocol of exchange with smart cards on the applicability of resource-intensive post-quantum algorithms of electronic signature in devices with limited resources using smart cards as an example and to provide recommendations for upgrading the standard protocol based on the analysis results. Research methods: information theory, systems analysis, object-oriented analysis. Research results: various scenarios of interaction with a smart card using the standard protocol of exchange are analyzed using the example of the smart card performing the function of calculating an electronic signature using the SLH-DSA postquantum algorithm standardized in the USA; as a result of the analysis, limitations of the standard protocol of exchange are shown, directly hindering the applicability of the SLH-DSA algorithm (and algorithms similar in characteristics) in smart cards. Scientific novelty: based on the results of the analysis, a direction of modernization of the standard protocol of exchange with smart cards is proposed for its adaptation to the characteristics of resource-intensive post-quantum algorithms of electronic signature; The proposed protocol upgrade will allow the use of a number of post-quantum cryptographic algorithms in smart cards.
