Smart Card is something that is used for data transactions quickly and practically. The definition of ”smart” is when a card has a chip implanted. The card is very helpful in the authentication and administration process even during emergencies, such as a patient healthcare record at the hospital. In this case study, patient data should only be accessed and known by people who have rights. So it is necessary for the security of data storage such as cryptography algorithms. The algorithm needed for patient cards is an algorithm that has fast processing capability and a high level of security. So the aim of this study is to implement the Tiny encryption algorithm on Smart Cards. Based on the results of testing in this study the time of encrypting patient data with a total of 600 lines of patient history measuring 30.6 Kb produces an average encryption time of 20.17 ms. While the decryption for the same data takes 17.21 ms which shows very little processing time and the tolerance for waiting time for accessing data. Furthermore, the Avalanche Effect test carried out in the TEA encryption process results 77%, where these results indicate that encrypted data has very random cipher-text results so that the data contents are kept confidential with a high level of security. The results of testing the processing time and AE can be concluded that TEA is an algorithm that has a fast data security process with high security and time that can be tolerated by users.

In this paper, a novel image encryption algorithm based on coarse-grained chaotic signals in which scrambling and diffusion are both covered. First, the chaotic signals are handled with unfixed coarse-grained key instead of been utilized directly. Second, both original image and derived chaotic signals are divided into bit signals form pixel values. In addition, high bits and low bits are also separated. Third, the high bits and low bits are scrambled with different methods at the same time and combined bit signals after scrambling are used to get the final results by global diffusion. At last, the image is encrypted and a corresponding decryption is designed to recover the encrypt image. In the simulation, properties including key space, information entropy, correlation analysis, key sensitivity and resistance to differential attack are provided to show the effectiveness and robustness of the high secure image encryption algorithm.

The security situation of mobile communication becomes even more grim, at present, the complete bug-free secure communications system solutions has not been found. For the realization of the end to end secure encrypted communication of speech, this paper proposes a speech encryption algorithm, which can penetrate compression encoder. The algorithm scrambles the speech signal in frequency domain based on FFT transformation domain in the sender, and it decrypts and reconstructs the signal in the receiving end. The encrypted speech signal still has the characteristics of speech, The residual intelligibility of the speech is low enough and the speech bandwidth does not be widen. Scramble matrix can meet the needs of speech transmission security and achieve one key for one secret communication flexibly. End-to-end communication can avoid the common eavesdropping and theft, and has a relatively broad prospects for development.

This paper proposes a new block encryption algorithm for cryptographic information protection. It describes a new transformation method EM (Exponentiation Module), which is part of the algorithm, and a method of S-box obtaining. The paper also considers an optimization technique to advance the efficiency of key selection and calculation. We discuss the possibility to obtain good results by applying the peculiar properties of cryptographic primitives in the Galois field. To increase the strength and speed of the encryption algorithm, we used a nonpositional polynomial notation and an indexed view for the Galois field. The paper provides for statistical properties of the ciphertext obtained with the developed algorithm. We also present the results of differential and linear cryptanalysis of the S-box used.

A New Chaos-Based Image-encryption and Compression algorithm

We propose a new and efficient method to develop secure image-encryption techniques. The new algorithm combines two techniques: encryption and compression. In this technique, a wavelet transform was used to decompose the image and decorrelate its pixels into approximation and detail components. The more important component (the approximation component) is encrypted using a chaos-based encryption algorithm. This algorithm produces a cipher of the test image that has good diffusion and confusion properties. The remaining components (the detail components) are compressed using a wavelet transform. This proposed algorithm was verified to provide a high security level. A complete specification for the new algorithm is provided. Several test images are used to demonstrate the validity of the proposed algorithm. The results of several experiments show that the proposed algorithm for image cryptosystems provides an efficient and secure approach to real-time image encryption and transmission.

An adaptive approach for securing patient data in intellectual disability care with 8D Hyperchaotic DNA encryption and IWT

引用

Intellectual disability (ID) is a neurodevelopmental disease characterized by significant intellectual and adaptive functioning impairments. Continuous monitoring and data collection are crucial for managing this condition. To collect patient's skin temperature data, doctors and caretakers often use thermal IR imaging, and they must securely share this information. To address privacy concerns and ensure robust encryption during data transmission, this study introduces an adaptive encryption algorithm that operates in both frequency and spatial domains. The algorithm counteracts various security threats, including plain text attacks, differential attacks, brute force attacks, and cropping attacks. The core of this research is the 8D Hyperchaotic DNA encryption algorithm, which enhances security by combining block scrambling with DNA coding. Security is further optimized through integrating the Integer Wavelet Transform (IWT) in the frequency domain and a DNA sequence in the spatial domain. The encryption process aims to balance security and computational efficiency, ensuring reliable performance. Extensive testing and validation against multiple types of attacks show the algorithm's effectiveness and reliability in practical applications. Experimental results show that the proposed system significantly enhances security against various attacks, thus setting a higher standard for encryption in biomedical image and signal processing. This algorithm shows potential for broader applications beyond intellectual disability care, including secure data transmission in medical imaging, financial transactions, and confidential communications, because of its robust encryption capabilities and adaptability to different data types.
