In the Shamir secret sharing scheme, we distribute a secret among q different users as follows. If our secret is a message (m₁,...,mk) from V(k, q) then, we encode it as a codeword of the Reed-Solomon R.Sk(q) and give one coordinate to each user. In this problem, we will use q = 7, k = 4 and the parity check matrix H₁ below for RS4(7). HA = 1 1 1 1 1 1 1 0 1 2 3 4 5 6 0 1 4 2 2 4 1 1. Write a generator matrix for RS4 (7) of the form Hq-k·

In the Shamir secret sharing scheme, we distribute a secret among q different users as follows. If our secret a message (m₁, ..., mk) from V(k, q) then, we encode it as a codeword of the Reed-Solomon RS (9) and give one coordinate to each user. In this problem, we will use q = 7, k = 4 and the parity check matrix H₁ below for RS4(7). HA = 1 1 01 1 1 1 1 2 3 4 5 6 4224 1 1. Write a generator matrix for RS4 (7) of the form Hq-k.
