(密)算唯一性的一个公开问题

An Open Question on the Uniqueness of (Encrypted) Arithmetic

Peter T. Breuer, Jonathan P. Bowen

摘要:

我们问是否两个或两个以上的算术图像可以通过不同的编码居住在同一个空间。这些答案对于一类处理器设计具有重要意义,这种设计以加密的形式进行所有计算,而不需要自己执行任何解密或加密。针对代数攻击的可能性对算法在一个“密码处理器”(KPU),我们提出了一种防御称为“ABC加密”,并显示这种加密如何使它不可能的观察算法被攻击者用来发现实际值。我们还展示了如何构建这样的加密算法。

英文摘要:

We ask whether two or more images of arithmetic may inhabit the same space via different encodings. The answers have significance for a class of processor design that does all its computation in an encrypted form, without ever performing any decryption or encryption itself. Against the possibility of algebraic attacks against the arithmetic in a `crypto-processor' (KPU) we propose a defence called `ABC encryption' and show how this kind of encryption makes it impossible for observations of the arithmetic to be used by an attacker to discover the actual values. We also show how to construct such encrypted arithmetics.
