2.0 Article Analysis
The article that that is considered for the critical evaluation of the different algorithms
associated with the encryption methodologies is provided below:

2.1 Intention and Content of the Article
The significant article depicts that the algorithms such as AES, RSA as well as DES
that are associated with the overall encryption of the data associated within the network
server. According to Mahajan and Sachdeva (2013), it can be analysed that encryption is
identified as a significant solution in respect to the overall security of the information systems
[1] . The noteworthy transmission of the data within the network server from a sender to its
specific receiver must be potentially encrypted in respect to the security of the data.
Moreover, the knowledge of cryptography puts a significant focus in respect to the encryption
as well as decryption techniques that will be used for the enhanced security of the data thus
adhering the overall consequences in respect to the security performance of the overall data
that are being transmitted within the network security [10]. In accordance to the performance
associated with the overall encryption methodologies it can be depicted that the security of
the data. In the further means, it can be identified to provide a great deal of effective data
transmission within the overall server.
The article clearly provides an overview of the encryption algorithms that are
significantly categorized as Symmetric as well as Asymmetric encryption methodologies.
The concept of symmetric algorithms or encryption methodology is depicted to use a single
key that will be used for the security of the data in both the sender as well as receiver end [8].
Moreover, the concept of asymmetric encryption methodology is identified to use two
different keys that is depicted as public as well as private keys. These two keys are used in
both the different aspects of the sender as well as the receiver for maintaining a security of
the data that are being transmitted within the network servers [4]. The usage of the two
different keys in respect to the asymmetric encryption method is depicted to be important,
related to the security of the data. In this procedure, the public key is associated with the
encryption procedure, whereas the private key is associated with the decryption part.

The further parts of the article clearly assesses the overall algorithms that are
important in respect to the maintenance of the data security as well as network enhancement
in terms of security. The significant algorithms associated with the encryption methodologies
are identified as the AES, RSA as well as DES [2]. These are critically assessed thus gaining
a potential knowledge in respect to the overall encryption methodologies.
DES: The first analysis that is carried out is in respect to the Data Encryption Standard
algorithm. This algorithm is depicted as the standard methodology that is associated with the
protection of the sensitive unclassified as well as commercial data [9]. This procedure
adheres the same key, which are to be used in respect to the decryption as well as encryption
procedures. The significant algorithm that is associated with the methodology of the DES
encryption technique is depicted in the following figure below:

The overall procedure related with the data encryption standard methodology is
depicted to be useful in regards to the security of the data.
RSA: The concept of the Rivest Shamir Adleman methodology associated with the data
encryption techniques is suggested to be another significant algorithm that deals with the
overall security of the data [6]. This algorithm is identified to deal with three significant steps
that are Generation of the Key, Encryption as well as decryption. The overall flowchart that
identifies the working of the significant encryption method is presented in the following

The potential usage of the asymmetric key algorithm in respect to the overall
procedure of this encryption technique helps the methodology to be significant in respect to
the data security within the overall network server systems [11].
AES: The advanced encryption standard is identified as the next security algorithm associated
with the overall security of the data associated within the network. The network
administrators mainly use this significant algorithm not only for the overall security but also
for the enhanced speed. The implementation of the software as well as the hardware
methodologies are described to be performing faster in respect to the usage of this algorithm
[7]. The potential steps associated with the overall management of the encryption of the data
and the decryption of the data that are being associated with the network servers. The
following figure depicts the overall algorithm associated with this encryption technique.

2.2 Discussion of Results
The significant result that is depicted in the considered article revolves round the fact
of the three significant data encryption as well as decryption of the data that flows within the
overall network systems [12]. The detailed explanation of the overall working procedures
associated with these data security techniques are clearly stated within the article that are
potentially analysed as well as evaluated and presented within the report. Moreover, the
comparison of these three types of data security algorithms are also provided within the
article. The comparison duly states the overall points that are stated below:
Key Size: The overall key size that is used by the AES algorithm is identified as 126,256 as
well as192 bits. In case of DES, the key size is identified as 56 bits whereas for the RSA
algorithm the key size is identified to be greater than 1024 bits.
Algorithm: In both cases of AES and DES, symmetric algorithm is used whereas only in the
case of RSA asymmetric algorithm is used [3]. Thus, the ciphering and the deciphering
algorithm is same for the RSA algorithm but the algorithm is different in both the cases of
AES and DES.
Implementation: The significant implementation of the hardware as well as software
becomes faster with the AES methodology whereas the hardware implementation is better in
the DES algorithm rather than in software implementation [5]. The implementation is not at
all efficient in respect to the RSA methodology.
2.3 Discussion of Conclusion
The significant article deals with the fact of the data security in respect to the
