摘要
目前已有用单片机实现的椭圆曲线密码,但在接口和实现速度上还不能很好地满足应用需求。本文针对这种不足,采用NIST推荐的曲线,结合USB接口技术和AVR单片机设计并实现了椭圆曲线密码卡,在卡中实现加密、解密、签名和验证。该卡具有保护私钥的功能,能较好地满足电子政务和电子商务中的应用要求。
ECC has been implemented in the Single-chip, but its interface and speed are limited. Based on NIST recommended, combined with USB and AVR Single-chip, we implement ECC cipher card with encryption, decryption, signature and verification. The card can protect private key and the card can satisfy practical application such as Electric Government and Electric Business.
