Selective Dictionary Encryption for Faster Boot and Data Access

The patent segments the digital data set into two distinct parts: a dictionary (containing compression algorithms and reference data) and compressed data streams. Only the dictionary is encrypted and stored in a first memory area, while the compressed data streams are stored in a second memory area. During booting, only the smaller dictionary needs to be decrypted, not the entire data set. This segmentation allows the system to maintain full data encryption for security while dramatically reducing decryption time during booting and pagination operations.

The patent applies preliminary compression to the digital data set before encryption and storage. The data is compressed using a dictionary-based compression algorithm during the data preparation phase, creating a compact representation that can be stored efficiently. During booting and pagination, the system only needs to decrypt and decompress the smaller dictionary structure, not the entire data set. This preliminary compression action reduces the amount of data that needs to be processed during critical boot and pagination operations, thereby reducing time loss while maintaining full data accessibility when needed.

The patent extracts the compression dictionary and reference data from the main data stream and stores it separately in a dedicated first memory area. The compressed data streams are stored in a second memory area. During decompression operations, the system only needs to load and process the extracted dictionary portion, not the entire compressed data set. This extraction separates the relatively small dictionary structure from the large compressed data, reducing the amount of data that needs to be processed during decompression operations while maintaining high memory space utilization through compression.
