1. Shovels and Shingles is a small construction company consisting of 12 computers that have Internet access. The company's biggest concern is that a wily competitorwill send e-mail messages pretending to be from Shovels and Shingles in order to get confidential information. Select an encryption solution that best prevents acompetitor from receiving confidential information and justify the recommendation.

Answer 1

1. Advanced Encryption Standard (AES) uses 256-bit cipher texts for encryption. AES encrypted data cannot be attacked and decrypted without using a brute-force search through all possible 256-bit keys. It is best algorithm for mobile security.

2. ECC, Digital Signature, AES, Blowfish

3. ECC, Blowfish

4. Secure Sockets Layer (SSL) - SSL is a commonly-used protocol for managing the security of a message transmission on the Internet)

5. Advanced Encryption Standard (AES) - AES is an encryption algorithm for securing sensitive butunclassified material by U.S. Government agencies.
