基于轻量级数字签名的药品防伪追溯系统的设计

Design of a Drug Anti-Forgery and Tracing System Based on Lightweight Digital Signatures

分析了现有防伪系统存在的问题与不足,提出通过将数字身份应用到药品领域的方法,实现药品的防伪、追溯和流向跟踪,并提出在消费者打开包装时销毁验证码,在验证时将药品信息、编码及查询次数等信息返回给消费者的方法.利用JUNA轻量级的数字签名技术设计了一个药品防伪追溯系统.JUNA生成的数字身份以32进制表示长度只有16个字符,有效地解决了现在数码防伪系统存在的密钥安全性、签名码长度过长等问题,提出了构建云计算平台验证中心的思想.

The problems and defects of existing anti-forgery system was analyzed and the method of applying digital identity to drug industry was also put forward in this paper, which realized anti-falsification, retrospect and flow direction track. Methods of destroying verification code while opening the package and ways of feeding back drug information, codes and flow direction track that was returned to customers while checking were put forward in this paper. JUNA lightweight digital signature technology was used to design a drug anti-forgery and tracing system. Digital identity formed from JUNA is only 16 characters long expressed by base-32 system, which can solve the problem of unsafe secret key and too long signature. Finally, constructing cloud computing platforms test center was taken into consideration.
