Explanation:
Elliptic curves are rich mathematical structures that have shown usefulness in many different types of applications. An elliptic curve cryptosystem (ECC) provides much of the same functionality RSA provides:
digital signatures, secure key distribution, and encryption. One differing factor is ECC's efficiency. ECC is more efficient than RSA and any other asymmetric algorithm.
Some devices have limited processing capacity, storage, power supply, and bandwidth, such as wireless devices and cellular telephones. With these types of devices, efficiency of resource use is very important.
ECC provides encryption functionality, requiring a smaller percentage of the resources compared to RSA and other algorithms, so it is used in these types of devices.
In most cases, the longer the key, the more protection that is provided, but ECC can provide the same level of protection with a key size that is shorter than what RSA requires. Because longer keys require more resources to perform mathematical tasks, the smaller keys used in ECC require fewer resources of the device.
Incorrect Answers:
A: Elliptic Curve Cryptography (ECC) has a higher strength per bit of key length than RSA.
B: Elliptic Curve Cryptography (ECC) has a higher strength per bit of key length than El Gamal.
D: Elliptic Curve Cryptography (ECC) has a higher strength per bit of key length than AES.

The modified Waterfall model was reinterpreted
to have phases end at project milestones.
Answer "Unlimited backward iteration is permitted" is false
because unlimited backward iteration is not permitted in the modified
Waterfall model.
Answer "The model was reinterpreted to have phases begin at project milestones" is a distracter.
Answer "Product verification and validation are not included" is false because verification and validation are included.
