What are the key limiting factors for cryptography on low-power devices?
Answer Options
There are system limitations on memory, CPU, and storage.
The devices cannot support public key encryption due to an inability to factor prime numbers.
There is a lack of chipset support for encryption.
Legal limitations for low-power devices prevent encryption from being supported.
Correct Answer: A
Explanation
Low-power devices typically have limited processor speed, memory, and storage, meaning that encryption can be a challenge. Fortunately, solutions exist that implement low-power cryptographic processing capabilities, and continued advances in processor design continue to make lower-power processors faster and more efficient. Legal limitations do not typically take into account whether a device is a low-power device, and public key encryption can be implemented on a wide range of CPUs and embedded systems, so factoring prime numbers is unlikely to be an issue.
