我们分析了一些已知的笛卡尔认证码,并利用(n≤r)(r+1)个q元密钥数字将它们修改成具有保密性的认证码,其中传输速率=r/n,其中n=2,3,…,1≤r−n−1。为此,我们使用了分组技术,本质上是使用相同的密钥分组技术来构造抵抗L≥2阶欺骗攻击的码。该方案的信息率为Alsor/n,并且需要(L+r)(n−r)个q进制密钥位。此外,这些代码允许可以重复使用先前发送的源状态。
We present an analysis of some known cartesian authentication codes and their modification into authentication codes with secrecy, with transmission rateR=r/n, wheren= 2, 3, ..., and 1 ≤r≤n− 1 using (n−r)(r+ 1)q-ary key digits. For this purpose we use a grouping technique.Essentially the same key grouping technique is used for the construction of codes that withstand spoofing attacks of orderL≥ 2. The information rate of this scheme is alsor/n, and it requires (L+r)(n−r)q-ary key digits. Moreover these codes allow that previously transmitted source states can be reused.
