Binary DNA Nanostructures for Data Encryption

Binary DNA Nanostructures for Data Encryption

We present a simple and secure system for encrypting and decrypting information using DNA self-assembly. Binary data is encoded in the geometry of DNA nanostructures with two distinct conformations. Removing or leaving out a single component reduces these structures to an encrypted solution of ssDNA, whereas adding back this missing "decryption key" causes the spontaneous formation of the messa...

Encryption of Binary and Non-Binary Data Using Chained Hadamard Transforms

This paper presents a new chaining technique for the use of Hadamard transforms for encryption of both binary and non-binary data. The lengths of the input and output sequence need not be identical. The method may be used also for hashing.

Multiple Binary Trees Encryption Principle

Through block cipher method, this paper demonstrates using preorder and post traversal sequence of a binary tree with 64 nodes to implement symmetric encryption/decryption. The different traversal sequences may determine a binary tree, so the method is vulnerable to be attacked. The paper’s further deduction involves improvement using multiple binary trees, so that more secure and efficient sym...
