Q100 / 100
In a constrained device implementing a TLS handshake, why might the choice of cryptographic algorithms (e.g., ECC vs. RSA) significantly impact feasibility?
Correct! Well done.
Incorrect.
The correct answer is A) ECC provides equivalent security with much smaller key sizes and less computational overhead than RSA, making it more practical for devices with limited CPU power, memory, and energy budgets
A
Correct Answer
ECC provides equivalent security with much smaller key sizes and less computational overhead than RSA, making it more practical for devices with limited CPU power, memory, and energy budgets
Explanation
TLS handshakes involve computationally expensive public-key operations; on constrained microcontrollers, the smaller keys and faster operations of ECC compared to RSA at equivalent security levels can make the difference between a feasible and infeasible secure connection given limited resources.
