In modern era, it should be noted that all work
related to banking, ATM card, credit card, marketing, Ecommerce
etc are done on internet. So there must be security
provided over the network. In this paper we survey the
researches held on various encryption methods used in
cryptography and attacks such as factorization problem, low
decryption exponent, common modulus, short message, cyclic
attack and side channel attack etc. This paper presents the
theoretical aspects and comparative study about different
encryption techniques in cryptosystem.

In this paper comparative study of different encryption
algorithms are presented. With theoretical aspects it was
concluded that the advanced encryption standard, RSA
public cryptography is more efficient than the Data
encryption standard. AES can be used when high security
is needed. This paper presents the theoretical analysis of
selected symmetric algorithms. These selected algorithms
are AES, DES, Blowfish, IDEA and RSA. All encryption
techniques are discussed and analyzed the working
performance of the encryption methods. This paper
presents survey on the existing works of the encryption
techniques and also presents various attacks in
cryptosystem. Each technique of encryption is different in
working, which might be suitable for different
applications. All the techniques are useful for real-time
encryption.
