In Encryption And Compression Of Data During Transmission, Which Of Them Would You Do First? Justify With Proper Reasons? |
|
Answer» If I had the option to encrypt and COMPRESS data, I would first compress the data. This is because of encrypting a data we obtain a stream of bits which are random. Now, these random bits become IMPOSSIBLE to be compressed, in other words, they are incompressible. The reason to why these random bits become incompressible is because of the lack of any PATTERNED STRUCTURE. Compressing data always requires any specific pattern to be compressed which is lacked in random bits. If I had the option to encrypt and compress data, I would first compress the data.
