  • Publication number: 20200242243
    Abstract: A method and a device for securing a cache against side channel attacks are provided. An allocator identifier ALLOCATOR field is added to each cache entry in the present disclosure. Whenever an entry is allocated in the cache, the identifier of the software domain currently running on the processor is filled into the ALLOCATOR field of the allocation entry. When accessing the cache, the cache entry can be hit only if the identifier of the software domain currently running on the processor is identical to the ALLOCATOR field in the cache entry. If the cache entry to be replaced is invalid or its ALLOCATOR field is identical to the identifier of the software domain currently running on the processor, then the existing entry in the cache is replaced directly; otherwise, the entire cache is emptied.

  • Patent number: 10667025
    Abstract: A framing method and apparatus in a passive optical network (PON) and a system, where the method includes generating a first transmission convergence (TC) frame and a second TC frame separately, wherein a sum of frame lengths of the first and the second TC frame is 125 microseconds (?s), performing bit mapping on the second TC frame to generate a third TC frame, where the bit mapping refers to identifying each bit of the second TC frame using N bits, and sending the first and the second TC frame to an optical network unit (ONU). A line rate corresponding to the second TC frame is lower than 2.488 giga bits per second (Gbps) such that a rate of a receiver on a receiving side is decreased and a bandwidth of the receiver is narrowed, thereby decreasing an optical link loss and increasing an optical power budget.

  • Patent number: 10657143
    Abstract: Attribute information of a pending data handling process to be performed is identified. Historical data handling processes for a same application scenario as the pending data handling process are identified based on the attribute information. A time that each identified historical data handling process is performed and methods used to perform the identified historical data handling processes are also identified. A weighting coefficient for each identified historical data handling process is determined. Weighted identified historical data handling processes are calculated by applying the weight coefficient to each identified historical data handling process. A recommended weight for each method used to perform the identified historical data handling processes is determined by combining weighted identified historical data handling processes that use the same method. A method that has the highest recommended weight to perform the pending data handling process is recommended.
