Security aspects come into play when it is necessary
or describe to protect the information transmission. The goal of
cryptography is to make it possible for two people to exchange a
message in such a way that other people cannot understand the
message. This thesis is intended to implement a secure
information system for critical applications. The key Derivation
Function is to calculate Keying data which is divided into two
keys, ENCkey and MACkey. ENCkey is used for encryption and
decryption the message and MACkey is used for message
authentication code( MAC) scheme to check the receiving
message is valid or not. The XOR Encryption scheme is used for
encryption operation. We compare the performance of Elliptic
Curve Cryptosystem(ECC) with other cryptosystem in terms of
key sizes; ECC has the same level of security with smaller key
sizes. So, ECC is used the smart and other critical applications
such as military departments, banking systems and etc. |
