Encryption Based on Binary Tree
Ke Qin · Experiment Science and Technology · 2006
This paper proposed an encryption algorithm based on binary tree. The algorithm is used to encrypt the plaintext by the figure of encryption binary tree. At the same time, the key can be kept by different keepers. Decryption algorithm is based on the character of traversing binary tree. This algorithm can turn ciphertext to plaintext by the sequences of inorder and preorder traversal without constructing a binary tree. So the algorithm can decrease space complexity.
