Yulan Kang, Linqing Huang, Yan He, Xiaoming Xiong, Shuting Cai, Haiyu Zhang
2020 Symmetry  
In this paper, a novel plaintext-related mechanism based on the peculiarity of plaintext DNA coding (PPDC) is presented and used to developed a symmetric image encryption algorithm.  ...  Many plaintext-related or non-plaintext-related image encryption algorithms based on chaotic systems have been found inefficient and insecure under chosen plaintext attacks.  ...  The founding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; nor in the decision to publish the results.  ...

2020 Bulletin of Electrical Engineering and Informatics  
The first case concerned on symmetric cryptography that involved DNA coding with OTP (one time pad) algorithms.  ...  Asymmetric cryptography was considered in the second case by incorporating the DNA codes in RSA algorithm. The efficiencies of DNA coding in OTP, RSA, and other algorithms were given.  ...  [21] 2011 This research includes an index-based symmetric DNA encryption algorithm. By using the block-cipher and index of string, the algorithm has a specific step for encoding the plaintext.  ...

A Novel and Efficient 3D Multiple Images Encryption Scheme Based on Chaotic Systems and Swapping Operations

Muhammad Hanif, Rizwan Ali Naqvi, Sagheer Abbas, Muhammad Adnan Khan, Nadeem Iqbal
2020 IEEE Access  
Single image encryption schemes are not efficient enough when a bunch of images is to be encrypted in some real-world setting.  ...  SHA-256 hash codes have been used to throw the plaintext sensitivity in the proposed cipher. Besides, a 256bit user key has been employed to increase the key space.  ...  The same indexes were then used for the substitution process which was based on the DNA.  ...

2021 Mathematical Problems in Engineering  
In this paper, a novel encryption scheme is presented for real-time audio applications. The framework of the proposed scheme is grounded on the principles of confusion and diffusion.  ...  The confusion incorporates nonlinearity by the application of Mordell elliptic curves (MEC) and a symmetric group of permutations S8.  ...  [43] came with a new audio encryption algorithm based on chaotic maps and DNA encoding. e algorithm offers reasonable security and achieves a prominent signal-to-noise ratio (SNR).  ...

2010 Proceedings of the 12th ACM workshop on Multimedia and security - MM&Sec '10  
To keep the protocol complexity as low as possible, a particular representation of fingerprint images, named Fingercode, is adopted.  ...  The proposed protocol follows a multi-party computation approach and makes extensive use of homomorphic encryption as underlying cryptographic primitive.  ...  The algorithm this paper focuses on, is based on a particular representation of the fingerprints which yields a relatively short, fixed length code, called Fingercode [4] suitable for matching as well  ...
