A new 128-bit block cipher
The evolvement of technology have resulted in a number of new proposals done on block ciphers such as KAMFEE, KAMKAR, ARIA, BLOWFISH256, DESL, REBC2, DSDP and etc. Even though there have been so much development of the block cipher, the industry still requires another block cipher as long as secu...

| 總結: | The evolvement of technology have resulted in a number of new proposals done on
block ciphers such as KAMFEE, KAMKAR, ARIA, BLOWFISH256, DESL, REBC2,
DSDP and etc. Even though there have been so much development of the block cipher,
the industry still requires another block cipher as long as security features are met.
Every country has different requirements when requesting block cipher so there is no
limit in developing them. According to the National IT Council (NlTC) report on
"Securing Malaysia Sovereignty in the CyberWorld" provided by Ministry of Science,
Technology and Innovation, Malaysia, they have outlined critical areas in which new
and additional research and development is needed to increase the protection of the
national information infrastructure. One of the critical areas is, secured
communication which helps to protect the confidentiality and integrity of information
during transmission and storage. Secured communication can be achieved by
encrypting and hiding data transmission when it is stored on a system. One of the areas which have been identified as priority with respect to secured communications is,
conventional cryptography which provides the fundamental security and privacy in the
information society. Towards that and after reviewing related research, in this research
we propose to come up with a new 128-bit block cipher cryptographic algorithm
which shall meet the security requirements.
This block cipher uses 128-bit for the key length and block size. It is an involution
substitution and permutation encryption network (SPN). This block cipher uses only
basic operations, key dependent S-box and XOR IS together so that it can be efficiently
implemented on various platforms. The strength of this system is measured by NIST
Statistical Test which evaluate from the point of view of the randomness of the block
cipher output.
From the results, this new block cipher has successfully generated randomness of the
block cipher output for data ranging from 1 ,000,000 to 6,000,000 bits. This means
that the new block cipher is secured to be used for data ranging from 1 ,000,000 to
6,000,000 bits. This block cipher is suitable to be applied to small devices such as
mobile phones and PDAs. The existence of this new 128-bit block cipher algorithm
will increase the protection of the national information infrastructure and also will
contribute as an alternative to other cryptographic algorithms in security in the
computing industry. |
