本文提出了一种新的信息加密方法。这种加密方法利用了数字全息的数值再现是基于全息图上记录的信息，任何一点全息信息的微小错位都会使数字全息的数值再现失败。本文引入三维旋转来打乱全息信息，利用旋转参数可以设计多个锁和密钥进行数据加密。通过数值实验验证了该方法对转角的敏感性，并对该方法引入的关键维数进行了粗略估计。结果表明，用旋转全息图进行数据加密是可行的。
Summary A new method for information encryption is presented in this paper. The new encryption method takes advantage of the fact that the numerical reconstruction of digital holography is based on the information recorded on the hologram, and any slight disarrangement of the holographic information will make the numerical reconstruction failed. 3D rotation is introduced in the paper to disarrange the holographic information, and the rotation parameters could be used to design multiple locks and keys for data encryption. The sensitivity of the rotation angles is tested with the numerical experiments and the key dimension introduced by this method is roughly estimated. The results presented here show that data encryption with rotated hologram is feasible.
