The security and portability of Java Card provides a reliable and effective way to ensure secure e-business.This paper describes implementation of NTRU Cryptography algorithm based on Java Card,provides a suite of Java Card API,and tests the performances of NTRU Cryptography algorithm based on Java Card.According to this test results in Java Card,comparing the highest NTRU security level to the 1024 bit RSA security level,NTRU is the same at encryption,6 times faster at decryption and 16 times faster at key...
