Answer:
A(n) <u>Cipher</u> or crypto-system is an encryption method or process encompassing the algorithm, key(s) or crypto-variable(s), and procedures used to perform encryption and decryption.
Explanation:
- Cryptography is such a technique that is used for the secure transfer of the information. We make codes for this purpose.
- Cryptosystem is such a system in cryptography is simply an encryption method that has three algorithms. One algorithm is used for the generation of key, one for encryption and decryption.
- Encryption is a process of converting the information in a data that is not understandable and decryption, this non-understandable data is converted into information so that we can read it.
Answer and Explanation:
a) Key for the relation courses is HS.
b) FD's are already minimal basis, as no attributes can be removed from the left side, right side is having only single attributes and none of the FD can be removed as given in the question.
c) By using the 3NF synthesis algorithm, the final set of relations obtained will be CT, HRC, HTR, HSR, CSG (FD'S are already proved to be minimal basis in part (b)). All the relations are in BCNF.
