In the modern digital era, the storage of digital data in multi-users systems and transmission over the internet is prime important in the society. The cryptographic technique is one of the possible solutions for protecting digital information for unauthorized uses. In this technique, the encryption algorithm should be simple to design and implementation. In the proposed article, a novel color image...
Security Solutions can never be completely and permanently developed. It may be true that One Time Pad might be one of the most complete Cryptosystems ever designed. That being said, it's not always that One Time Pad can be used. There are many applications where a lightweight but powerful Cryptosystem is required. This is where CRYPSTER comes in. The CRYPSTER is a modification on the platform of...
In this paper, a genetic secret key based technique for neural encryption (AGKNE) has been proposed for online transmission of data/information in wireless communication. In this method both the communicating party receive the similar input vector, generate an output bit and are trained based on the output bit. Length of the key depends on the number of input and output neurons. Synchronized identical...
This is an encryption and decryption algorithm with the help of genetic functions cryptography. This new algorithm is developed for encryption and decryption process. This algorithm combines the features of Genetic Algorithm in Cryptography. Here we generate random numbers for “Crossover” and “Mutation”. The encryption and decryption algorithms will be made public. The algorithm contains a key, which...
In this paper, a neural network guided secret key based technique for encryption (ANNRPMS) has been proposed using recursive positional modulo-2 substitution for online transmission of data/information through wireless communication. In this approach both the communicating networks receive an indistinguishable input vector, produce an output bit and are trained based on the output bit. The dynamics...
In this paper the concept of binary field arithmetic is used to generate block cipher. The technique consists of five stages, where in each of first four stages binary field arithmetic based substitution technique along with key association process is used. The lengths of input and output blocks in these four stages are identical and they are 256 bit, 128 bit, 64 bit and 64 bit, respectively. The...
