Abstract:
In neoteric time, network and data security has become most relevant concern because of
the volume of exchange hypersensitive data over internet flourishing day by day. Many
approaches are obtainable in the field of data security, one is that “Cryptography”. In
cryptography, when data is transferred from sender to receiver data is encrypted by
encryption algorithm and inversely when it received by the receiver it is decrypted using
decrypted algorithm to view the exact and real data that send by the sender before. There
are many procedure for data encryption .Such as: AES, DES, RSA algorithm. In this
paper a new algorithm proposed which is CRSA (Chaotic random seed algorithm)
technique for data encryption and decryption. Also compared CRSA with existing
algorithms and their performance. This paper also provides experimental result to analyze
those algorithms and our propose CRSA algorithm.
Description:
Data communication technology getting more advance and more susceptible to handle
huge amount of data within a short time. So data security is most important issue to
maintain these data to protect any fault or harm. To protect data encryption and
decryption methods are most popular and used method in now a days. There are two
types of encryption and decryption: Symmetric and Asymmetric keys. They are also
known as Private and Public keys encryption. In asymmetric algorithm’s both public and
private key is used. [1].For encryption public keys are generally used as well as private
keys used for decryption. [2]. There are various types of encryption procedure like as
AES, AES-256, DES, 3DES and RSA. All of them are designed based on symmetric or
asymmetric keys where some of them used both that means public keys for encryption
and private keys for decryption. Example: RES.
