Which of the following types of cryptography should be used when minimal overhead is necessary for a mobile
Elliptical curve cryptography
Regarding the performance of ECC applications on various mobile devices, ECC is the most suitable PKC
(Public-key cryptography) scheme for use in a constrained environment.
Note: Elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic
structure of elliptic curves over finite fields. One of the main benefits in comparison with non-ECC cryptography
(with plain Galois fields as a basis) is the same level of security provided by keys of smaller size. Using smaller
key size would be faster.
