Abstract
It is described a method for encrypting and a method for decrypting at least a portion () of a dataset being stored in a memory (), wherein the dataset has at least two dimensions. The described multi-dimensional cryptographic methods comprise forming a first keystream () being assigned to a first dimension of the dataset and forming a second keystream () being assigned to a second dimension of the dataset. The encrypting method further comprises encrypting each data packet of the portion () of the dataset by using a combination of the first keystream () and the second keystream (). The decrypting method further comprises decrypting each data packet of the portion () of the dataset by using a combination of the first keystream () and the second keystream (). It is further described a method for temporarily storing at least a portion () of a dataset into a memory () and a device for handling a dataset, which method and which device take advantage of the above-described encrypting method and/or the above-described decrypting method.
