A study on Android-based real number field elliptic curve key table generation

Abstract

Encryption algorithms are used to protect data, but encrypted data depend on the safety of the key used in the encryption algorithm, so it is very important to generated a key that cannot be easily inferred for a safer protection of data. For this, in order to broaden the choice of keys used in encryption algorithm, this paper proposed the method to generate a key table by expanding the previously proposed elliptic curve algorithm to real number field, and the proposed method was applied to Android-based smartphone cryptosystem for verification. © 2012 Springer-Verlag.
