Abstract

U ovom radu opisana je kriptografska shema za kriptiranje podataka s očuvanjem redoslijeda. Detaljnije su opisani osnovni algoritmi i kriptografski postupci kojima je takva shema ostvarena. Također je opisana modifikacija čiji je cilj optimizacija performansi osnovnih algoritama. Implementirani su programi osnovne i modificirane sheme. Testirane su razlike u vremenskom odzivu, potrošnji memorije, broju izmijenjenih poruka te utjecaji raznih parametara na performanse algoritama.

Abstract (english)

This paper describes a cryptographic scheme for encrypting data while preserving the order. The basic algorithms and cryptographic procedures used to implement such a scheme are described in detail. Additionally, a modification aimed at optimizing the performance of the basic algorithms is presented. Programs for both the basic and modified schemes have been implemented. Differences in response time, memory consumption, the number of exchanged messages, and the impact of various parameters on algorithm performance have been tested.
