Abstract :
All the aspects of human life are driven by
information in the present era. Hence, need to protect
useful information from malicious activities such as attacks.
Security is playing a vital role in the field of
communication system and Internet. Providing security
services to the important data under timely manner against
attacks are the challenges in the security related
communities. Cryptographic ciphers have an important role
for providing security to these confidential data against
unauthorized attacks. During the practical implementation
of these cryptographic ciphers for various applications,
there are various factors that can affect the performance
and selection of cryptographic algorithms including
security which is an important factor. This paper discuss
about the desperate attacks and procedures for selecting
cryptographic algorithms with respect to performance.
