In applications where key compromise would have very serious consequences or where the security must remain valid for many years into the future, key lengths of 2,048 bits are used. Note that performing exponentiation with numbers of this size is expensive in terms of computing resources. , DES) would be around 100 times faster than RSA, while hardware implementations would be between 1,000 to 10,000 times as fast. 8 Elliptic curve cryptography In 1985, Victor Miller [26] and Neil Koblitz [27] independently proposed the use of elliptic curves for use in public-key algorithms.

The elliptic curve cryptosystem (ECC) is an analog of existing public-key cryptosystems in which the security of the system depends on the discrete logarithm problem over points on an elliptic curve.

A plaintext block X undergoes n rounds of operations to produce an output block Y. Each operation is based on the value of the nth round key. The round keys are derived from the cipher key by first expanding the key and then selecting parts of the expanded key for each round. 7 shows an overview of the process. 2 The round transformations Each round except the last is composed of four different operations. The last round is equivalent to the other rounds with the MixColumn step removed. The round operations guarantee that there are no linear relationships between the input and the output of a round.
