摘要

在这项工作中，我们描述了一种同态密文的消息打包和解包方法。消息被打包成明文多项式的系数。我们提出了一个解包过程，它允许为每个打包的消息获得一个密文。在基于云的应用程序中，特别是在发送同态计算结果时，密文的打包和解包代表了一种减少传输瓶颈的解决方案。我们得到的结果(装箱比、拆箱时间)与现有的基于转密码的装箱方法进行了比较。

Another Compression Method for Homomorphic Ciphertexts

In this work we describe a message packing and unpacking method for homomorphic ciphertexts. Messages are packed into the coefficients of plaintext polynomials. We propose an unpacking procedure which allows to obtain a ciphertext for each packed message. The packing and unpacking of ciphertexts represents a solution for reducing the transmission bottleneck in cloud based applications, in particular when sending homomorphic calculations results. The results we obtain (packing ratio, unpacking time) are compared to existing packing methods based on trans-ciphering.
