摘要： The present invention relates to a method of converting an encrypted data set into an encryption of individual bits representing the data set. Further, the invention relates to a system for converting an encrypted data set into an encryption of individual bits representing the data set. A basic idea of the present invention is to provide a protocol in which it is possible to divide an encryption of a data set in the form of e.g. a biometric feature, such as a number x, where x e {0, 1, ..., n-1 }, into an encryption of respective bits x 0 , x 1 , ..., x t-1 forming the number x, where t is the number of bits of the number n-1, without leaking any information about x or its bits x 0 , x 1 , ..., x t-1 Hence, the present invention enables splitting of the encryption [[x]] into the respective encrypted bits [[x 0 ]], [[x 1 ]], ..., [[x t-1 ]] forming the encrypted number x=?I=1 n x i 2 i .
摘要翻译：本发明涉及一种将加密的数据集转换成对代表数据集的各个位进行加密的方法。此外，本发明涉及一种用于将加密的数据集转换成代表数据集的各个位的加密的系统。本发明的基本思想是提供一种协议，在该协议中可以将例如数据集的形式的数据集的加密划分成多个部分。将诸如x的生物特征，其中xe {0,1，...，n-1}分解成相应比特x _{0 ，x _{1 ，...，x t-1 形成数字x，其中t是数字n-1的位数，而不泄露关于x或其位x _{0的任何信息因此，本发明使得能够将加密[[x]]分割成各自的加密比特 [[x _{0 ]]，[[x _{1 ]]，...，[[x _{t-1 ]] 数字x =？I = 1 x _{i 2 ^{i 。}}}}}}}}

摘要： A wearable accessory controls (103) and provides security for a pill delivering medical substances and services. An initialization procedure allows decryption information (814) to be loaded into the accessory for each pill and/or decryption information (818) about the accessory to be loaded into the pill. The pill preferably sends encrypted messages to the accessory and the accessory preferably sends encrypted messages to the pill. The pill operates only when the proximity of the accessory is verified or authenticated during the operation of the pill, preferably at frequent intervals. Where the pill is no longer useful, its information can be deleted (1205) from memory in the accessory or other controlling device.

摘要： The invention relates to a method (MA; MB) of testing similarity of a first DNA-related data to a second DNA-related data under encryption based on a feature-based encryption scheme in conjunction with a secure two-party computation scheme is provided. Employing a secure two-party computation scheme allows testing similarity of the first 5 DNA-related data to the second DNA-related data. The outcome of this comparison, i.e. the test result, may be made available to an authorized party. If the test result is negative, no information about the first DNA-related data and the second DNA-related data is revealed. If the test result is positive, only limited information about the first DNA-related data and the second DNA-related data may be revealed to an authorized party.

摘要： It is described a RFID device (231a, 231b, 231c, 331) comprising a data memory (236) and an electronic circuit arrangement (237, 238, 239, 247) coupled thereto. The electronic circuit arrangement has a first and a second operational configuration, wherein by receiving a control command (250a) the electronic circuit arrangement can be switched irreversibly from the first to the second configuration. The RFID device further comprises a communication interface (245) being coupled to the electronic circuit arrangement. In the first configuration the RFID device is adapted to communicate with a standard RFID reader (110) via the communication interface. In the second configuration the communication with the standard RFID reader is disabled and the RFID device is adapted to communicate with a readout-RFID device (370). The RFID device may be equipped with a secondary communication interface that can be used to communicate with the RFID device in a privacy- preserving manner. After the RFID device has been disabled, the secondary interface can be used to access data in a secure manner.

摘要： The present invention relates to a method and apparatus for encrypting data (105) by means of a first key (115), and a method and apparatus for decrypting encrypted data by means of a second key (185). The present invention alleviates the need for exact key information by allowing encryption of data (105) by means of a first key (115) and subsequent decryption of the encrypted data by means of a second key (185) without the need for the first key (115), provided that the first key (115) and the second key (185) form a sufficient estimate of an encryption/decryption key pair. During encryption, multiple encryption keys (135), at least in part based on the first key (115), are used to encrypt a redundant representation (122) of the data (105). The encrypted data (124) may subsequently be decrypted by using multiple decryption keys (165) based on the second key (185), without the need for the first key (115), provided that the second key (185) forms a sufficient estimate of the first key (115).
摘要翻译：本发明涉及借助于第一密钥（115）对数据（105）进行加密的方法和装置，以及用于通过第二密钥（185）对加密数据进行解密的方法和装置。本发明通过允许通过第一密钥（115）加密数据（105）并且随后通过第二密钥（185）对加密数据进行解密而不需要第一密钥（185）来缓解对确切密钥信息的需要（115），只要第一密钥（115）和第二密钥（185）形成加密/解密密钥对的充分估计。在加密期间，至少部分基于第一密钥（115）的多个加密密钥（135）被用于加密数据（105）的冗余表示（122）。如果第二密钥（185）形成足够的估计值（125），则加密数据（124）可随后基于第二密钥（185）通过使用多个解密密钥（165）解密，而不需要第一密钥（115）的第一键。

摘要： The present invention relates to a method and a device (104) for authenticating a plurality of physical tokens (101, 102, 103). A basic idea of the invention is to supply a sequence of interconnected devices (108, 109, 110), each device comprising a physical token (101, 102, 103), with a challenge of the respective physical token created during enrollment of said respective physical token, wherein the sequence of interconnected devices is arranged such that a data set supplied to the sequence is cryptographically processed with a response of a token comprised in a device and passed on to a token comprised in a subsequent device which further cryptographically processes the processed data set with its response until a response of a final physical token has been used to further cryptographically process the data set. Then, the data set which has been cryptographically processed with the responses of the tokens in the sequence is received and used together with the data set itself and data associated with the response of the respective token to authenticate the sequence of physical tokens.

摘要： A method of automatic agreeing on a set of attributes between a plurality of stations in a computer network. The method includes, in each station, determining at least one respective set of attributes that is acceptable for the station to be agreed with the other station. The attributes of the sets are selected from a predetermined list of attributes. The method uses a multi-party computation protocol to determine the agreed set based on the determined respective acceptable sets without revealing other information than a willingness to accept the agreed set.
