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.

Abstract: A method and device for secondary input of text are disclosed. The method may include: detecting a touch action, if the touch action meets a triggering requirement for a candidate split mode, activating the candidate split mode, and in the candidate split mode, selecting and splitting one of candidate results into an acceptable part and a pending part, wherein the acceptable part is presented in a target text field and a new candidate is acquired based on the character string corresponding to the pending part. With the present disclosure, users are allowed to modify a candidate result at any time as desired by retaining an accepted part of the candidate result during the input process, so as to simplify the input process. This entails a more prompt and more efficient input feedback mechanism which simplifies the user's manipulation and improves the user's experience.
