Select Appropriate Encryption Algorithms1. Shovels and Shingles could use the digital signature, Secure Sockets Layer or the Data Encryption Standard to send their messages.
2. Top Ads could start with the Blowfish because it is software and smartphones run off of software.3. NetSecIT would have different choices, but I would offer to start with RSA because they could send all the info with a private key and then it could only be decrypted with their public key.4. Backordered Parts would use Secure Sockets Layer of course, but they could also RSA just for the added security encryption.
AES would also work really well for this company due to the fact that they are a military based company that handles confidential information.5. Confidential Services Inc. would most definitely need to use the AES based encryption.
