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.

A novel type of water-soluble isatin derivatives, and manufacturing method and application thereof. An isatin derivative comprising a phenolic hydroxy group is used as the substrates. A dimethylaminomethylene group is introduced to an ortho position of the phenolic hydroxy group to significantly improve the water solubility of a class of compounds provided by the invention. An antitumor activity study showed that the activity of the class of compounds was not reduced, and even improved. The class of compounds has great prospects for applications in developing an antitumor pharmaceutical product.
