Algorithm 7:Encrypting mapped points using the shared group point.

Input:

M a p p e d p o i n t s (x_{i}, y_{i}), g k_{s h}

Output:

C i p h e r t e x t s

S e n d e r : C a l c u l a t e g k_{s h}

;

f o r i = 0; i < n o o f m a p p e d p o i n t s B; i + +

;

(c_{x i}, c_{y i}) = g k_{s h} + (x_{i}, y_{i})

;

S e n d e r : r e p e a t u n t i l f i n i s h

;

(c_{x i}, c_{y i}) \leftarrow t h e r e s u l t s
