Titre : Benchmarking of Threshold Symmetric Encryption Schemes: Performance Analysis and Limitations Type de document : document électronique Auteurs : Abd El Krim Sekhri Zeggar ; Zibouda Aliouat, Directeur de thèse Editeur : Setif:UFA Année de publication : 2025 Importance : 1 vol (22 f .)

Amortized Threshold Symmetric-key Encryption (ATSE)
Central processing unit (CPU)Index. décimale : 004 Informatique Résumé :
This study explores the practical implementation and integration of two advanced
threshold symmetric-key encryption frameworks: Distributed Symmetric-key Encryption
(DiSE) and Amortized Threshold Symmetric-key Encryption (ATSE). By distributing
cryptographic operations across multiple parties, both schemes ensure that
secret keys remain never fully reconstructed, thereby enhancing security in collaborative
environments. DiSE introduces a robust distributed architecture for symmetric
encryption, while ATSE optimizes computational efficiency over repeated operations
through amortization techniques. This project evaluates their performance focusing on
latency and throughput. The experiments were done on a local machine simulating a
distributed scheme where each of the CPU thread representing a node. Further more
the experiment was setup while simulating a 10ms network delay to fully align with
the papers work. The results achieved were for a small number of nodes while providing
more metrics measurements than the papers all while trying minor modifications
to discover the advantages and limitations of each algorithm while maintaining the
original idea.Note de contenu : Sommaire
