摘要： A method for controlling access of a user to a secondary system. A primary system receives, from a user system connected to the secondary system, first authentication information comprising an encryption of a random string. The encryption of the random string is a user-specific key. Second authentication information is generated from protected secondary authentication data stored in the primary system. Generation of the second authentication information includes applying the user-specific key to the protected secondary authentication data to generate the second authentication information. The second authentication information is provided to the secondary system to enable access of the user to the secondary system.

摘要： Embodiments are directed towards resynchronizing the processing of a monitored flow based on hole detection. A network monitoring device (NMD) may be employed to passively monitor flows of packets for a session between endpoints. The NMD may receive copies of the monitored flow and perform processes on the monitored flow. In some situations, some copies of packets may not be fully processed by the NMD, creating a hole in the processing. If a hole is detected in the monitored flow and the processing of the monitored flow is desynchronized, then the NMD may suspend processing until it is resynchronized or for a remainder of the session. If the processing is desynchronized, then the NMD may resynchronize the processing by resuming the processing of the monitored flow at a downstream position of the monitored flow based on the detected hole.
摘要翻译：实施例旨在基于空穴检测重新同步所监视的流的处理。可以采用网络监视设备（NMD）来动态地监视端点之间的会话的分组流。 NMD可以接收被监视流的副本，并对监视的流执行进程。在某些情况下，数据包的某些副本可能未被NMD完全处理，在处理中创建一个孔。如果在监视的流中检测到一个孔，并且所监视的流的处理被去同步，则NMD可以暂停处理，直到它被重新同步或者在剩余的会话中。如果处理是不同步的，则NMD可以基于检测到的孔在监视流的下游位置恢复监视流程的处理来重新同步该处理。

摘要： A stream encryption method encodes plaintext of N number of 1-bit input, signal sequences into L (L is N or more) bits of encrypted text using N number of pseudo random sequences and uses only one pseudo random sequence used for the encryption to decode the single corresponding plaintext. This stream encryption method comprises using the N number of pseudo random sequences to divide a L-bit encryption symbol set, averagely into two equal parts; selecting either of the two partial sets by a corresponding 1-bit plaintext sequence; and when there are one or more elements of the selected N number of partial sets forming common parts in the sets, using one of those as an encryption symbol.

摘要： A system and method for producing cryptographic keys for use by an embedded processing device within a manufactured product. A pseudo random number generator is seeded with entropy data gathered by the embedded device, and the result is used to generate a public-private key pair. The process can be carried out during manufacturing so that the public key of each manufactured product can be stored in a database along with a unique identifier for the embedded device associated with the key. In one particular example, a vehicle having an installed telematics unit uses the key generating process to self-generate keys using entropy data available to the vehicle.
