A New Symmetric Key Quantum Cryptographic Algorithm

2007 National Radio Science Conference, 2007
Based on the principles of both classical and quantum computation primitives, a new symmetric key quantum cryptographic algorithm is proposed. This algorithm can be used to encrypt classical binary messages as well as quantum information. Encryption and decryption are implemented by the aid of classical and quantum computation which can be realized by ...

Tamilian Cryptography: An Efficient Hybrid Symmetric Key Encryption Algorithm

Wireless Personal Communications, 2019
Cryptography is one of the most accepted and successful data security methods used at present by most of the organizations. Encrypting the message using natural languages reduces the encryption time and improves the performance. Tamil is a most ancient Dravidian language spoken in the southern part of India.

RASS — A concurrency based bitwise symmetric key cryptographic algorithm

2016 IEEE 7th Annual Ubiquitous Computing, Electronics & Mobile Communication Conference (UEMCON), 2016
The security and strength of any cryptosystem's encryption depend on the difficulty, both in terms of time and technique, of cracking the message. This paper suggests a bit cipher, a symmetric key cryptographic algorithm which provides bit-level security with linear time complexity and robust security (two 16 bit keys), and uses optimal time compared ...

Cognitive Symmetric Key Cryptographic Algorithm

2012
Today, Cryptographic schemes play a major role in storage, retrieval and transfer of data and code in a secured manner. The major factors which determine the efficiency of a cryptographic system are computational speed, level of security provided, cost effectiveness and key size of the algorithm. Choosing the optimal bit size for keys in encryption and

Design and analysis of an ARQ based symmetric key generation algorithm

2011 - MILCOM 2011 Military Communications Conference, 2011
The main idea in this paper is to design and analyze a symmetric key generation algorithm whereby we can strengthen wireless network security. Our main goal is generating a sequence of highly secure secret keys based on an ARQ based transmission mechanism that relies on the statistical independence of channel errors between the attacker and legitimate ...
