摘要： The invention provides a method of generating arbitrary numbers given a seed, characterized by providing a challenge derived from the seed to a physical token, receiving an initial response from the physical token, combining the initial response with helper data associated with the challenge to produce a stable response, and generating the arbitrary numbers using a pseudo-random number generator using the stable response as a seed for the generator. Preferably one or more of these pseudo-random permutations are used as one or more round function(s) in a Feistel block cipher. The generated arbitrary numbers may also be used to create a cryptographic key.

摘要： It is described a method for encrypting and a method for decrypting at least a portion (155) of a dataset being stored in a memory (150), wherein the dataset has at least two dimensions. The described multi-dimensional cryptographic methods comprise forming a first keystream (165) being assigned to a first dimension of the dataset and forming a second keystream (175) being assigned to a second dimension of the dataset. The encrypting method further comprises encrypting each data packet of the portion (155) of the dataset by using a combination of the first keystream (165) and the second keystream (175). The decrypting method further comprises decrypting each data packet of the portion (155) of the dataset by using a combination of the first keystream (165) and the second keystream (175). It is further described a method for temporarily storing at least a portion (155) of a dataset into a memory (150) 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.

摘要： This invention relates to a method and system for providing digital security by means of a reconfigurable physical uncloneable function, RPUF. The RPUF comprises a physical system constituted by distributed components arranged to generate a first response when receiving a first challenge at a point of the physical system. The physical reconfiguring of the RPUF comprises redistributing the components such that they generate a second response, which differs from said first response, when again applying the first challenge at the point. The reconfiguration step is further utilized in providing secure storage for digital items. The digital item is data of any kind, including data that needs to be accessed and updated, i.e. which is dynamic in nature. The method is exemplified by implementations such as secure storage of a key, a secure counter and a seed generator.
