摘要： A vehicle authenticates a component class of a prospective component for use in the vehicle by obtaining from a certification authority a certification that an authentic component of the component class is associated with a second cryptographic key. The certification certifies that the second cryptographic key is bound to information identifying an authentic component of the component class. The vehicle utilizes the second cryptographic key obtained from the certification authority in cryptographic communication with the prospective component, and determines whether the prospective component is an authentic component of the component class based on whether the second cryptographic key is successfully utilized in the cryptographic communication.

摘要： Simultaneously detecting both frame and bit synchronization in a serial bit stream reduces the time required to have a receiver lock up to a transmitted serial data signal. A dual-phase correlator circuit is used to detect frame synchronization while a multiphase commutator circuit detects bit clock synchronization.

摘要： Blind access (100, 300, 400) to a desired encryption key of a predetermined first group member is provided to a second group. The first group encrypts a plurality of first group member encryption keys using a predetermined algorithm and transfers to the second group, the encrypted plurality of first group member encryption keys with corresponding unencrypted first group member identification fields, IDs, and a list of IDs corresponding to the first group members. The desired ID-free encryption key is selected and encrypted by the second group using a predetermined algorithm. The doubly encrypted key is transferred to the first group, decrypted by the first group and transferred to the second group for decryption. Thus, the encryption key is provided without knowledge to the first group of which member's encryption key is being examined and with knowledge to the second group of only the desired encryption key.

摘要： A cryptographic apparatus for encrypting and decrypting digital words includes a mechanism that permits a cipher algorithm to be electronically stored after the manufacture of the apparatus. The storing mechanism includes at least one electrically erasable, programmable gate array containing a portion of the cipher algorithm and at least one random access memory device coupled to the array for storing digital data generated by the algorithm. A mechanism which is coupled to the gate array and memory device controls the execution of the algorithm for each digital word thereby decrypting encrypted digital words and encrypting non-encrypted digital words.

摘要： A communication network (10) includes any number of interconnected nodes (20), including a sending node (22), a sending gateway (24), a receiving gateway (26), and a destination node (28). A low capacity or expensive communication channel (30) resides between the sending and receiving gateways (24, 26). An original digitally signed message is sent from the sending node (22) toward the destination node (28). When the original message arrives at the sending gateway (24), the original signature is verified. If verified, the sending gateway (24) shrinks the original message into a reduced message and re-signs the message with a gateway digital signature before sending the message onward through the communication channel (30) toward the destination node (28). The destination node (28) verifies the gateway digital signature against the reduced message and is not required to de-compress the reduced message into a precise duplicate of the original message.

摘要： A system and method for accessing digital content purchased by a rights owner for a first computing device. The method receives a proxy from the rights owner that includes rights to the digital content granted to the rights owner, stores the proxy on a second computing device, and determines whether the rights owner is present at the second computing device. When the rights owner is present at the second computing device, the method enables the proxy, and accesses the digital content on the second computing device through the proxy.

摘要： A system and method to securely create, distribute, install and execute selected features of software on wireless devices combines three different types of licenses, a validation license, a digital rights management (DRM) license, and a feature license with a software application. Each of these three licenses work independent of each other, where the validation license helps prevent malicious code from executing on wireless devices, the DRM license prevents unauthorized copying of the software application and the feature license securely enables or disables specific features of the software application. The system also allows a wireless device to unwrap a DRM protected software application, to validate the software application, to enforce DRM usage rules and to execute selected features of the software application.
