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 |
