SPACE AND SECURITY EFFICIENT DYNAMIC KEY GENERATED HYBRID BLOCK CIPHERING METHOD FOR ENCRYPTION

Abstract

We proposed our new encryption algorithm with reduce space complexity and increase security. There are two most important parameter or characteristics space and security. This proposed work is all about the new encryption and decryption process. Encryption process is based on two concepts: First dynamic key generation and second one is block encryption. Key generation and block encryption will be done in .NET and we will measure the effectiveness of the proposed work on the parameters like: memory complexity and security. Memory complexity is measured in KB and security of work will be measure through Avalanche Effect. This work will be very effective. In this proposed work data security will be increase and space capacity should be reduce. It is the establishment of all data security focuses. The systems used to this end have wound up being powerfully numerical of nature. Set up cryptosystems is immediate, effortlessly acknowledged and simple to be broken. We proposed a new cryptographic algorithm based on  symmetric key block cipher that provides better security and reduce space complexity.
