Abstract:
A software/data transmitting and receiving method comprising:arbitrary selecting at least two basic encoding algorithms from a predetermined plurality of basic encoding algorithms; generating a new encoding algorithm based on at least said selected two basic encoding algorithms; encoding software/data from a software/data provider with the new encoding algorithm; transmitting the encoded software/data and a combination information identifying a combination arrangement of said at least two basic encoding algorithms used for encoding the software/data to a software/data receiver; receiving in a software/data receiver the encoded software/data and the combination information; selecting at least two basic decoding algorithms and a combination arrangement of the basic decoding algorithms in accordance with said combination information received by said software/data receiver; generating a new decoding algorithm, based on the selected basic decoding algorithms and the combination information; and decoding the software/data with the new decoding algorithm.
