I want to implement Shamir’s Scheme in C# ,and I don’t understand how can be obtained the secret, corresponding shares (I1 .. I5),
and how can be reconstructed secret ?
in exemple: 1.1

I think I1=8 from P(1) mod 11; but I2 = 10 != p(2) mod 11
Thanks.
If you mean you want to implement it yourself: perhaps you’re better off posting this question on: https://crypto.stackexchange.com/ .
If you just want to do cryptography in C#: check out http://msdn.microsoft.com/en-us/library/system.security.cryptography.rsacryptoserviceprovider.aspx
