Scheme

Advantages

Drawback

H. Junuru et al.’s Scheme [10]

Can be embedded on devices that have limited computational & storage capacity.

Reduce the computational cost of signer.

Can not reduce the computational cost of verifier.

H. Li et al.’s Scheme [11]

Speed up the computation of Elliptic Curve

Scalar Multiplication without extra memory

Suitable for hardware implementation.

Small growth rate with k-bit length.

None

S. Lamba et al.’s Scheme [12]

No of point addition, multiplication and doubling.

Improve execution speed and security

Reduces no of parameters made public.

Removes the overheads with regards to calculating the parameter r.

None
