| 20080229119 | Information Carrier Authentication With a Physical One-Way Function - The present invention relates to a method of enabling authentication of an information carrier ( | 09-18-2008 |
| 20080231418 | Integrated Physical Unclonable Function (Puf) with Combined Sensor and Display - The present invention relates to a device ( | 09-25-2008 |
| 20080237506 | Integrated Puf - In a device for providing challenge-response pairs a radiation detection element, a challenge-modifying element and preferably also a light source are arranged on the same side of an imaginary plane, which separates said radiation-detecting element from a radiation scattering element. Hence, generation of a speckle pattern having a desired minimum speckle size is facilitated and a more easily assembled device is provided. | 10-02-2008 |
| 20080260152 | Proofs of Vicinity Using Cpufs - The present invention relates to a method and a device ( | 10-23-2008 |
| 20090008924 | AUTHENTICATING BANKNOTES OR OTHER PHYSICAL OBJECTS | 01-08-2009 |
| 20090153841 | OPTICAL SCANNING DEVICE - An optical identifier ( | 06-18-2009 |
| 20090183248 | TWO-WAY ERROR CORRECTION FOR PHYSICAL TOKENS - The invention relates to a method of establishing a shared secret between two or more parties, based on a physical token, wherein helper data from both the enrolment and the authentication measurement is used in such a way that only response data reliable at both measurements is used to generate the shared secret. The generated shared secret is therefore identical to both parties to a high degree of certainty. The invention further relates to a system for generating such a shared secret, comprising a central database server and a terminal, or any one of them. | 07-16-2009 |
| 20090208019 | METHOD AND APPARATUS FOR ENCRYPTING/DECRYPTING DATA - The present invention relates to a method and apparatus for encrypting data ( | 08-20-2009 |
| 20090217045 | PHYSICAL SECRET SHARING AND PROOFS OF VICINITY USING PUFS - The present invention relates to a method of creating challenge-response pairs, a method of authenticating a plurality of physical tokens, a system for creating challenge-response pairs and a device for authenticating a plurality of physical tokens. A basic idea of the invention is to interconnect a plurality of physical tokens ( | 08-27-2009 |
| 20090244518 | OPTICAL IDENTIFIER COMPRISING RANDOMLY ORIENTED PARTIAL FACES - The invention relates to an optical identifier ( | 10-01-2009 |
| 20090282259 | NOISY LOW-POWER PUF AUTHENTICATION WITHOUT DATABASE - The present invention relates to a method of authenticating, at a verifier ( | 11-12-2009 |
| 20100122093 | METHOD, APPARATUS AND SYSTEM FOR VERIFYING AUTHENTICITY OF AN OBJECT - The invention relates to a method for proving authenticity of a prover PRV to a verifier VER, the method comprising generating a secret S using a physical token by the prover PRV. Obtaining a public value PV by the verifier, where the public value PV has been derived from the secret S using a function for which the inverse of said function is computationally expensive. The method further comprising a step for conducting a zero knowledge protocol between the prover PRV and the verifier VER in order to prove to the verifier VER, with a pre-determined probability, that the prover PRV has access to the physical token, where the prover PRV makes use of the secret S and the verifier VER makes use of the public value PV. The invention further relates to a system employing the method, and an object for proving authenticity. | 05-13-2010 |
| 20100215173 | DATA SECURITY | 08-26-2010 |
| 20110021229 | METHOD FOR COMMUNICATING IN MOBILE SYSTEM - The present invention relates to a method for communicating from a primary station to a plurality of secondary station, comprising the step of at the primary station allocating a resource to the secondary stations over the time on the basis of a hash function, wherein the hash function is such that the probability that two secondary stations are allocated common resources in two sub frames substantially equals the product of the probability that the two secondary stations are allocated a common resource in the first subframe and the probability that the two secondary stations are allocated a common resource in the second subframe. | 01-27-2011 |
| 20110099117 | DEVICE, SYSTEM AND METHOD FOR VERIFYING THE AUTHENTICITY INTEGRITY AND/OR PHYSICAL CONDITION OF AN ITEM - A physical uncloneable function (PUF) pattern is used for verifying a physical condition of an item. The PUF pattern is arranged to be damaged in the event that said item is exposed to a predetermined environmental condition. Verification of the physical condition of the item, is carried out by obtaining a measured response from the PUF pattern, and comparing the measured response with a stored response in respect of the PUF. | 04-28-2011 |
