I want to apply this expertise at work by constructing MD5 hashes to identify large volumes of data. The legitimacy of the data may therefore be validated using the identity. The MD5 hashing method, for example, may be used to generate a file identifier that changes anytime the related file is modified (Mohamed et al., 2020). I may utilize the same approach in the future to detect fraudulent network activities by establishing a unique hash for each data packet and watching for changes in the hash value.

Lab 7.4.1 Applying Symmetric Key Encryption

I was expecting to learn more about symmetric key encryption and its use in guaranteeing data security during transmission. Not only did I not learn how to properly transmit the key, but I also did not grasp the foundations of symmetric key encryption, such as utilizing a shared key to encrypt and decrypt data. Regrettably, I was unable to explore this critical part of ensuring data is securely sent via a network in the lab.

Rather than continue with this lab, I recommend moving to one in which we may securely transfer the shared key around. Diffie-Hellman key exchange algorithms, as well as the secure derivation, storage, and transmission of the shared key, should be taught in the lab. The lab must explain in full how to properly store the shared key in a database and how to limit access to the key to just authorized users. Such an approach would be more complete and would increase one's understanding of the security protections for data transfer provided by symmetric key encryption.
