Implementation of Class for Arbitrary Precision Class for Public Key Crypto API based on Java Card

摘要

Recently, The international scramble far electronic business market is being raised on earth. The security and portability of Java cards provide a safe, reliable, convenient, and effective way to ensure secure e-business and to enable a broad range of new application. But. Java cards represents one of the smallest computing platforms in use today. That is, a major factor influencing the design and implementation of Java Card is the limited availability of computing resources. Thus, In this papers, We design and implement immutable arbitrary precision integer on Java cards.
