Demonstrate the error-correction operation by changing the fifth bit of your encoded message and showing how the correct message can be recovered. Show what happens if the first and second bits of your encoded message are both changed, and comment on your answer.

    This question is about how many codewords there can be in a ternary linear code. Note that m is the number of codewords, not the length of the code. A ternary code uses the symbols 0, 1 and 2 with the properties that 1+1=2, 1+2 = 0, and 2+2 =1. Note that m is the number of codewords, not the length of the code. For each of m = 1, 2, 3, 4, and 9 write down a ternary linear code of length 2 containing m codewords, or explain why there is no such code. In general for what m does there exist a ternary linear code with m codewords? Justify your answer, referencing any research you have done. Marks will be deducted for failure to reference research correctly using the Harvard system.

    Hi. I need a cryptography programmer who can code for me a highly sophisticated elliptic curve cryptography key generator (preferably using OpenSSL) which I can hash with SHA-256. If ECC is too complex, RSA may also be substituted as a replacement as I believe both of these methods use a public and private key. I already have the working SHA-256 hash code but I need someone to help me with the ECC or RSA code. The idea would be that we would hash the data and then sign the hash. This will prove that whoever generated this hash has the private key. Then you get the data that you want to verify, calculate the hash on it and then check that. If the calculated hash matches the one in the signature then the signature is valid. At this point we will have have high confidence that...
