Modular arithmetic and semi elgamal encryption
I'm implementing a semi ELGamal cryptosystem(from a research paper) function that has been used in PVSS. Unfortunately, I fail to decrypt as it has been described in the algorithm.
Here is the initialisation phase:
Select a secure prime p such that…

How represent message for Elgamal EC?
I am working on my project that uses elgamal elliptic curve.
I know when the elgamal ec encrypt by following steps
Represent the message m as a point M in E(Fp).
Select k ∈R [1,n−1].
Compute C1 = kP.
Compute C2 = M +kQ.
Return(C1,C2).
Where Q is…

How represent message in elgamal elliptic curve Scheme?
I read about elgamal elliptic curve Scheme but I didn't understood how it represent message in this algorithm. If the message m has 128 bit and base point b(x,y) and private key k1 and public key is pub= k1 * b.now Is message m should be is…
