Item A secure way to message based on internet protocol on RSA algorithm using DNA encoding with laplace transform computing /(Springer Nature, 2024-01-01) Sirisha, P.Security plays a vital role in transmitting confidential information. Cryptographic algorithms are essential in providing data security against malicious attacks. The DNA- based cryptographic algorithm is one of the valuable methods for protection. RSA algorithm is widely used in the popular implementations of Public Key Infrastructures. This model presents a new approach to show how cryptography works in DNA computing. It could also transmit messages securely and effectively using the RSA algorithm with Laplace Transform belonging to public key cryptography. DNA computing technique and Laplace Transform with RSA algorithm to encrypt the message are used in this model. The proposed model shows the frequency, time, and statistical analysis to get good results.Item New password embedding technique using elliptic curve over finite field /(Springer Nature, 2019-01-01) Sirisha, P.In the present sophisticated digital era, safe communication of user password from one source to the other is quite difficult in client/server system. Also storing the password as it appears increases the potential risk of the security. Protection of the password is at most important in group communications to avoid the access of the illegal person to group resources. In addition, a roaming user who uses the network from different client terminals requires access to the private key. The present paper explains secure communication of password from one entity to the other. Here the password is encrypted using elliptic curve over finite field, embedded in a large random text at different selected positions, and communicated to the receiver via public channel.Item Secure Cryptosystem based on Braiding/Entanglement of Pauli 3/2 Matrices /(IJCA, 2016-06-17) Sirisha, P.As the internet is the basic means of communication nowadays,secure transmission of the sensitive information to the genuine recipient has become a Herculean task. Cryptography is an essential tool for protecting information in computer systems. This paper presents a novel encryption scheme using Braiding/Entanglement of Pauli Spin 3/2 matrices.Item Cascade block cipher using braiding/entanglement of spin matrices and bit rotation /(CERN, 2016-03-31) Sirisha, P.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.Item Cascade Block Cipher Using Braiding/Entanglement of Spin Matrices and Bit Rotation /(IJNSA, 2016-03-30) Sirisha, P.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.
