| 摘要 |
A method of encrypting data using a sequence of two or more data compression algorithms wherein the output of one algorithm is the input of the next algorithm if any and one or more algorithms each produce output embodying one or more codec dictionaries and one algorithm produces output not embodying a codec dictionary which algorithm uses an external pre-existing codec dictionary as its source of references. Further where if more than one algorithm emits output embodying a codec dictionary, one such algorithm operates on bytes of input and another operates on bits of input. |
