Abstract
To reduce the effectiveness of eavesdropping attacks, a filler such as one utilized in a data frame for link-layer LAPDm signaling may be dynamically selected to utilize a first bit pattern (first filler) generated utilizing a first algorithm when the transmissions are unencrypted, and to utilize a second bit pattern (second filler) generated utilizing a second algorithm different from the first algorithm when the transmissions are encrypted.
