摘要： Method and apparatus for compressing data representing a set of symbols such that each symbol (12) of the set can be separately accessed and decompressed. Each symbol of the set of symbols is encoded (63) in the form of a two-part code wherein a first part of the code is common for all encoded symbols and a second part of the code encodes the data representing a symbol. An identifier is given for each symbol for permitting each encoded symbol to be separately accessed and decompressed. The invention is particularly useful for storing large fonts such as a Chinese or Japanese character set.

摘要： Methods and systems taught herein allow communication device manufacturers to preconfigure communication devices to use preliminary access credentials to gain temporary network access for downloading subscription credentials, and particularly allow the network operator issuing the subscription credentials to verify that individual devices requesting credentials are trusted. In one or more embodiments, a credentialing server is owned or controlled by the network operator, and is used by the network operator to verify that subscription credentials are issued only to trusted communication devices, even though such devices may be referred to the credentialing server by an external registration server and may be provisioned by an external provisioning server. Particularly, the credentialing server interrogates requesting devices for their device certificates and submits these device certificates to an external authorization server, e.g., an independent OCSP server, for verification. A common Public Key Infrastructure (PKI) may be used for operator and device certificates.

摘要： A technique for handling data provided from a source node (120) to a collecting node (130) in a data network (100) is described. As to a method aspect of the technique, the source node (120) generates a sequence of values. The sequence is unrevealed in the data network (100) by the source node (120) in a time interval. An authentication of the sequence is triggered in the data network (100). The authentication associates the sequence with the source node (120). One or more signatures for one or more data sets to be sent in the time interval are computed using one or more values of the sequence. The one or more data sets in the time interval are sent from the source node (120) to the collecting node (130). The source node (120) further provides one or more of the signatures.

摘要： An electronic device (300) comprising a digital logic circuit (101) and a test module (302) for testing the digital logic circuit is provided. The test module is adapted to generate test patterns based on a key and test parameters, apply the test patterns to the digital logic circuit, receive test responses from the digital logic circuit, compact the test responses into a test signature, and determine a test result (115) by comparing the test signature with an expected signature. The electronic device further comprises a writable storage means (311) for storing the key and the expected signature, and an interface (312) for writing the key and the expected signature to the writable storage means. Since the key and the expected signature are configurable after manufacturing, the provision of hardware Trojans during manufacturing is hampered, for the reason that an adversary does not have complete knowledge of the test patterns which will be generated during the lifetime of the electronic device.
