Signed-binary representations of integer k with symmetric digit set Dscrs - {-(2w - 1 ),-(2w-3),... ,-1,0,1,... ,2w - 3,2w - 1} may have lower weight than the unsigned-binary expansion of k. The "weight" is the number of nonzero digits in a binary expansion. Lower weight leads to fewer number of addition operations in the scalar multiplication, kP, of elliptic curve cryptosystems. Here P...
We present a new source coding scheme with smaller expected length than Shannon-Fano-Elias codes. The ordering of source symbols input to the proposed encoding algorithm can be arbitrary. We show that this property leads to exponential complexity for eavesdropping even though an adversary knows the code construction rule and the probability mass function of the source
