Algorithm 8:Decrypting cipher texts using the shared group key.

Input:

E n c r y p t e d p o i n t s (c_{x i}, c_{y i}), g k_{s h}

Output:

D e c r y p t e d p o i n t s

R e c i p i e n t : C a l c u l a t e g k_{s h}

f o r i = 0; i < n o o f E n c r y p t e d p o i n t s B; i + +

;

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