Comparative Study of the Characteristics of Modern Asymmetric Encryptions

Resumo

This paper presents a comparative study of five common asymmetric encryption algorithms with the objective of identifying one that is appropriate for satisfying a set of requirements by software developers normally working in a client-server environment. The five modern asymmetric algorithms within the scope of this paper are identified through reviews of current software. The performance indicators are derived through the basic definition of what is a good encryption algorithm, and the data for these indicators are obtained through literature review and computer simulations. Quantitative analysis method of selecting an encryption is presented, and applied to these five common algorithms, with data of their performance indicators and the user’s preferential weights, to demonstrate the rationale in making a decision (of selection).
