“…In [17] Association rules for variability of key using parameterized approach have been constructed for prediction of future parameters for construction of key from hacker's perspectives. In [18], the cryptic algorithm developed from Fibonacci-Q matrix [10,14,15] under various situations say hacker is interested to mine future keys, future key sequences, and probable steady state situation using Markov process. The stochastic analysis and future recommendations for ensuring security is presented in [18,20].…”

Cryptanalysis is very important step for auditing and checking strength of any cryptosystem. Some of these cryptosystem ensures confidentiality and security of large information exchange from source to destination using symmetric key cryptography. The cryptanalyst investigates the strengths and identifies weakness key as well as enciphering algorithm. With increase in key size the time and effort required to guess the correct key increases so trend is increase key size from 8,16,24, 32, 56, 64, 128 and 256 bits to strengthen the cryptosystem and thus algorithm continues without compromise on the cost of time and computation. Automatic Variable Key (AVK) approach is an alternative to the approach of fixing up key size and adding security level with key variability adds new dimension in the development of secure cryptosystem. Likewise, whenever any new cryptographic method is invented to replace per-existing vulnerable cryptographic method, its deep analysis from all perspectives (Hacker / Cryptanalyst as well as User) is desirable and proper study and evaluation of its performance is must. This work investigates AVK based cryptic techniques, in future to exploit benefits of advances in computational methods like ANN, GA, SI etc. These techniques for cryptanalysis are changing drastically to reduce cryptographic complexity. In this paper a detailed survey and direction of development work has been conducted. The work compares these new methods with state of art approaches and presents future scope and direction from the cryptic mining perspectives.

“…Bhunia [5][6][7] proposed the Automatic Variable Key technique for practical approaches of security in the year 2006. There are many researchers like Goswami [10][11][12][13][14][15][16][17], Banerjee and Dutta et al [8][9] invented more secure techniques based on Automatic Variable Key (AVK) by increasing the randomness, standard deviation and root mean square among the auto generated key sequences. The aim of our techniques is to secure the key from unauthorized persons and tom hide the secret keys from others and to generate more random keys as compared to the existing key generation techniques.…”
