Review on Light Weight-Cryptography and Future Challenges

Cryptography is the study of hiding information. It is the method of reworking on the message to make them secure and resistant to attack .In cryptography the original message is converted into other message at the encryption side and reconverted into original message at the receiver side. For constrained devices normal cryptographic algorithms can be too slow, too big and time consuming. The term Light weight cryptography studies new algorithms to outdo this problem. This technique is generally used for resource constrained devices. (RFID tags & WSN are EGS) Light -weight encryption is a combination of two terms "light and weight "and it is a sector of a classical cryptographic algorithms. Light weight encryptions and decryptions are implemented on platforms as well as hardware and software. This paper presents the analysis study on the common use of recent hardware and software implementations of symmetric and asymmetric ciphers.
