Vantages of Adaptive Multidimensional Playfair Cipher over AES-256 and RSA-2048
Main Article Content
Abstract
Adaptive Multidimensional Playfair Cipher (AMPC) has the capacity to provide secrecy to all kinds of data. The primary objective of this research is to compare this cipher with the standard ciphers AES-256 and RSA-2048, and find the advantages of AMPC over them. The comparisons are done on the basis of encryption and decryption times, plain data size versus cipher data size, possible number of keys and types of data supported. It is found from the comparison analysis that the AMPC is more efficient in terms of memory and bandwidth utilization when compared to the standard ciphers. AMPC and RSA-2048 are always unambiguous whereas in case of AES-256, data size has to be a multiple of 16 bytes or padded values shouldn’t be a part of original data values in order to be unambiguous. Also, AES-256 is very weak against brute force attack when compared to other two ciphers. Among AMPC and RSA-2048, former is more efficient in terms of time, memory and bandwidth. Therefore, applications desiring to secure all types of data unambiguously and efficiently with respect to memory and bandwidth consumption irrespective of data size can use AMPC.
