【摘要】 综合采用公密钥加密、分组加密、数字签名等数据加密技术,提出了一种有效解决基于GPRS通信的嵌入式应用系统中数据通信安全问题的机制。通过实例验证,可以有效防范伪造、窜改、重发等常见的恶意攻击。更多还原

【Abstract】 In the paper,an efficient way on information security mechanism of GPRS- based embedded application system is introduced,which comprehensively integrates such data encrypt technology as Public Key encrypt,Block encrypt and Digital signature,etc.It proves with example that the security mechanism can efficiently avoid those familiar baleful attacking as frau- dulent attacking,tamper attacking,resend attacking,etc.更多还原
