Description

1. Assume you have been asked to select a cryptographic “package” to help secure your company’s message system. What criteria would you use to select the package? Obviously, among other things, you would need to consider technical specifications, but which specifications and on what basis can you compare them? What other considerations are there? Why do you believe your selection criteria make sense? Include at least 1 reference in APA format for initial response.

2. In section 7.3 of the textbook, it says that “the final message sent will consist of i encoded as a 32-bit integer, least significant byte first, t, followed by the encrypted mi and ai.” Is it OK that the message number is not encrypted or MACed? Include at least 1 reference in APA format for initial response.

The cryptographic system offers security for all the resources that require transmission
from one source to another and static systems. For a messaging system, cryptography is
essential for secured communication between the company's employees. To select the best
cryptographic package for a messaging system, the technical consideration is; does the package
offer end-to-end encryption for the messaging system (Bai, Pearson, Kelley, & Mazurek,
2020). End-to-end encryption offers security from the device level, and the message can be
opened only if the final device destination is reached. This prevents intercepting of the
messages by third-parties as the only parties who can open the messages are the sender and
intended recipient.
Other considerations for a cryptographic package are how it interacts and integrates
with the messaging system. Ds the package cover both the system and the transmission or
covers either (Kessler, 2022). The cryptographic package that fits the messaging sy...
