摘要： In one embodiment, it is proposed a method for providing information to determine a graph associated with a data item, said graph being representative of a history of said data item in a network, and said graph comprising a set of vertices and a set of edges, each vertex being associated with an electronic device (101) of said network, and each edge linked at least two vertices being representative of a dataflow between said at least two vertices. The method is executed by an electronic device (101) and is remarkable in that it comprises:
- verifying if an hash information derived from an obtained data item is comprised in a list of tracked data item (307) comprising a list of hashes, each hash being a hash of a first information related to a data item;
- in the case that said hash information derived from said obtained data item is comprised in said list of tracked data item (307), transmitting in said network said information to determine a graph comprising a hash of a second information related to said obtained data item, when said obtained data item is obtained by said electronic device (101), and/or transmitted to another electronic device (203) in said network and/or a derived data item from said obtained data item is generated.

摘要： A search server (220) receives a search query comprising at least one keyword from a device (210), performs (S12) a search and generates (S13) a response that is returned to the device (210). The response comprises the number of hits found in the search and, for each keyword, an indication of the number of hits a subsequent search excluding the keyword would return. In a preferred embodiment, the response also comprises a number of additional keywords and indications on the number of hits a subsequent search including the additional keywords would return. The response is displayed (S14) to a user, the indications can be given as a number or as graphical modifications - e.g. size or colour - to each keyword. The user can then use the information in the response to refine the request by removing or adding a keyword.

摘要： A network (100), advantageously a home network, comprises a number of user devices (110), for example personal computers, game consoles and smartphones, each having an estimator application (111), preferably voluntarily installed by the user. The network (100) further comprises a network device (120) that acts as an interface between the network (100) and an external network. The estimator applications (111) measure (210) the network traffic for its user device (110), while the network device (120) in parallel generates (220) an independent measurement of the network consumption. The measurements are then compared (230). If the difference between the sum of the measurements from the estimator applications and the measurement of the network device is below a fixed threshold, it is assumed that the measurements are valid for the considered measurement time interval. Otherwise, the difference is an indication that at least one estimation was incorrect.

摘要： A method for detecting a version of a client software (210) in a network. A server (220) receives (201) a first request from the client software (210), sends (203) a first response comprising a first challenge to the client software (210), receives (205) a second request comprising an answer to the first challenge from the client software (210), and detects (207) the version of the client software (210) from at least the second request. The answer to the challenge is dependent on the version of the client software (210) and is expressed as a modification to a communication protocol used for the first and the second request. Also provided are a server (220), a client (210) and a computer program product (240).

摘要： A graphical password system. A device (400) displays a background image (110) and a number of icons (130). In order to generate a password, a user selects (320) the background image (110) and then iteratively selects (330) and places (340) a number of icons on the background image (110). The user then instructs the device to generate (360) the password based on the background image (110), the selected icons (130) and their location, and possibly the order of input. As the placed icons (130) preferably modify the displayed screen, the invention can enable the creation of a semantic graphical password, which is easy to retain, while it at the same time is possible to make the password strong.

摘要： A method for discovering emulated clients. A verifier (20) sends (206) a cryptographic challenge C to a client (10) and starts (208) a timer (22).

The verifier (20) then stops (214) the timer (22) and verifies (216) that the result is correct and (218) that the response was timely. Also provided is a verifier (20).

摘要： A controlled system (110, 120) performs internal taint tracking of data items. When a data item is created, the controlled system computes (202) a name and a taint for the data item and performs (204) an initialization function, thus informing a tracking entity (130) that of the name and data of the data item. The taint is propagated to further data items, while the name may change, and when a data item is exported to (210) or imported from a further device, the controlled system informs (216; 224; 232) the tracking entity (130) of the name and taint of the exported or imported data item as well as its source and destination. A controlled system (110, 120) may request (236) a propagation history from the tracking entity (130). As the tracking entity (130) is shared by more than one controlled system (110, 120), it is possible to perform taint tracking across controlled systems even if these do not use the same taint tracking framework.

摘要： The invention is directed to a proxy re-encryption scheme with limited delegations. To generate a ℓ-level ciphertext for a message, wherein ℓ is an integer, a ℓ-level ciphertext enabling ℓ - 1 re-encryptions and L -1 is a maximum number of possible re-encryptions, a processor (112) generates, in a ℓ-level group of prime order p , a ℓ-level encryption key for the ℓ-level ciphertext from a public key and a ℓ-level generator for the ℓ-level group; obtains a first ciphertext component by multiplying the message with a generator of a final group of a multi-linear configuration with L levels, the generator being raised to the power of an integer exponent; obtains a second ciphertext component by taking the ℓ-level encryption key to the power of the integer exponent; and outputs the ℓ-level ciphertext comprising the integer ℓ, the first ciphertext component and the second ciphertext component. In a preferred embodiment, the processor (112) includes an indicator of a time period in the ℓ-level ciphertext; and, if the integer ℓ > 1, obtains a third ciphertext component by taking a hash value over the time period to the power of the integer exponent and includes the third ciphertext component in the ℓ-level ciphertext that is output. Also provided are the re-encryption and decryption counterparts.
