Abstract:
Cryptography is one of the most important
sciences in the current area. Elliptic Curve
Cryptography (ECC) has attracted the attention of
researchers and product developers due to its
robust mathematical structure and highest
security compared to other existing algorithms.
ECC provides greater security more efficient
performance than the first generation public key
technique.In this paper, application for elliptic
curve cryptosystem work as symmetric
cryptographic system by investigates fromindexing
dictionary technique. This system is implemented
to transfer secret messages between the sender
and receiver using indexing dictionary technique
for English text. The dictionary technique is just a
list ofwords orsecure sentences. This dictionary is
constructed to 841 secure messages stores in
database. These messages are encoded to ECC
indexing points and ECC points are used as
indexes of dictionary in this system. These indexes
of points are encrypted and decrypted instead of
encrypting the text messages. In this system, linear
feedback shift register (LFSR) is used to generate
the secret key. Secret permutation and inverse
permutation key is used to increase randomized
for points sequence of data. This system test it by
execute encryption and decryption process with
more flexible and efficient.
