Abstract: Method and apparatus for transforming data in a data processing system. A first portion of a block of data is transformed using a first key having a first number of bits, and a second portion of the block of data is transformed using a second key having a second number of bits different than the first number of bits. One of the first and second keys provides an increase in transformation speed while the other of the first and second keys provides an enhanced degree of data security.

Abstract: HTTP/HTML is enhanced to provide information to a server about the current usage level of the continuous data that is being sent to the client. With this information, the server is able to tailor the data being sent to the client based on the current usage level. If the usage level changes in the client system, the server receives information about the changed level and the amount of data being sent is adjusted (up or down) accordingly. The client (browser) is enhanced to determine and send the current usage status and the server is enhanced with the intelligence to tailor the data it sends based on the current usage status received from the client.
