摘要
文中通过对智能卡协议规范ISO/IEC 7816的研究,提出了一种应用于安全芯片的COS系统的设计方案。该系统能够有效地调用安全芯片中非对称算法RSA及国密对称算法SM1等算法资源。其中,生成的RSA私钥可以得到有效地保护和存储,私钥加密用作数字签名,对应的RSA公钥用于对数字签名的验签;SM1算法用于加密通信,对报文进行加解密处理,实现信息的安全防护。测试结果及试点情况表明这种设计方案具有实际的应用价值和良好的使用效果。
By the study of ISO/IEC 7816 for the smart card,the design of a COS for the secure chip is presented,which can effectively call the resource of cryptographic algorithm in the secure chip,such as RSA and SM1.Among them,the private key of RSA can be effectively protected for digital signature and the corresponding public key is used to verify the digital signature.Besides,the SM1 is used for the encryption and decryption of packet in the encrypted communication so as to implement the information security.Test results and pilot program show that the discussed design may provide practical value and good effects.
