Cryptography is the study of techniques for ensuring the secrecy and authentication of the information. Public -key encryption schemes are secure only if the authenticity of the public-key is assured. Elliptic curve arithmetic can be used to develop a variety of elliptic curve cryptographic (ECC) schemes including key exchange, encryption and digital signature. The principal attraction of elliptic curve cryptography compared to RSA is that it offers equal security for a smaller key-size, thereby reducing the processing overhead. In the present paper we propose a new encryption algorithm using Elliptic Curve over finite fields.
Secure communication of the sensitive information in disguised form to the genuine recipient so that an intended recipient alone can remove the disguise and recover the original message is the essence of Cryptography. Encrypting the message two or more times with different encryption techniques and with different keys increases the security levels than the single encryption. A cascade cipher is stronger than the first component. This paper presents multiple encryption schemes using different encryption techniques Braiding/Entanglement of Pauli Spin 3/2 matrices and Rotation of the bits with independent secret keys.
Cryptography is the study of methods of sending messages in disguised form so that only the intended recipients can remove the disguise and read the massage. With widespread availability of computer technology, the rapid growth of wireless communications secured exchange of information has become a challenging task. The most basic of the modules in modern cryptography is that of a primitive, which may be regarded as a cryptographic building block which performs one or more desired functions, and may be combined with others to form a cryptographic protocol. The most well-known and perhaps the simplest primitive is encryption, which allows parties to achieve confidential data transmission over an insecure channel. In the present paper we proposed a cryptographic technique using elements of a finite field and logical operators basing on inverse property. To test the efficacy of the proposed scheme the cryptanalysis is performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
