The following operarations for EC points are available:
doubleUpmultiplying a point by itself
+point addition
leftmostBithighest bit value of an integer
ANDlogical and-operator for two integers
*multiplication of an integer scalar with an EC point
doubleUp(ecp) ## S4 method for signature 'ECPOINT' doubleUp(ecp) ## S4 method for signature 'ECPOINT,ECPOINT' e1 + e2 leftmostBit(x) ## S4 method for signature 'bigz' leftmostBit(x) AND(x, y) ## S4 method for signature 'bigz,bigz' AND(x, y) ## S4 method for signature 'ECPOINT,bigz' e1 * e2 ## S4 method for signature 'bigz,ECPOINT' e1 * e2
