ecoperators: Elliptic curve operators

Description

The following operarations for EC points are available:

doubleUp

multiplying a point by itself

+

point addition

leftmostBit

highest bit value of an integer

AND

logical and-operator for two integers

*

multiplication of an integer scalar with an EC point

Usage

doubleUp(ecp)
# S4 method for ECPOINT
doubleUp(ecp)
# S4 method for ECPOINT,ECPOINT
+(e1, e2)
leftmostBit(x)
# S4 method for bigz
leftmostBit(x)
AND(x, y)
# S4 method for bigz,bigz
AND(x, y)
# S4 method for ECPOINT,bigz
*(e1, e2)
# S4 method for bigz,ECPOINT
*(e1, e2)

Arguments

ecp
