Aiming at the hidden danger of information security caused by the lack of medical big data information security firewall, this paper proposes a security privacy protection method for hospital big data based on hybrid encryption algorithm. First, collect hospital big data including hospital medical business system, mobile wearable devices and big health data;Secondly, use byte changes to compress hospital big data to achieve safe transmission of hospital big data;Then, the hospital sender uses the AES session key to encrypt the hospital big data and the ECC public key to encrypt the AES session key, uses SHA-1 to calculate the hash value of the medical big data, and uses the ECC public key to sign the hash value;The hospital receiver uses the ECC private key to verify the signature, and decrypts the AES session key using the ECC private key. After the AES session key decrypts, the hospital big data, the hospital big data security privacy protection is completed. The experimental results show that the method is superior to conventional ECC algorithm or RSA and AES hybrid encryption algorithm in terms of encryption and decryption time and security strength. The average correlation coefficient of encrypted hospital big data is only 0.0576, and the RL curve value is low and gentle. The encrypted data has good scrambling effect and low privacy leakage probability, which ensures the confidentiality and integrity of medical data in the transmission process.

Blockchain technology ensures the integrity and transparency of data access control by keeping an unchangeable record of all transactions. Fog computing increases efficiency by dispersing cloud computing skills throughout the network's superiority and reducing latency in data access and authentication processes. The objective of this study is to develop a blockchain and fog computing model that implements secure data access control mechanisms for distributed data storage and authentication using a hybrid encryption algorithm. The model aims to provide secure and reliable data storage by leveraging the decentralized nature of blockchain and the proximity of fog computing to the data source. Additionally, the hybrid encryption algorithm (HEA) enhances data security by combining multiple encryption techniques for robust protection against unauthorized access. This study proposes a novel blockchain and also the Fog Computing Model (FCM) that ensures secure data access control, distributed data storage, and authentication. The model utilizes a HEA and is based on the Deep Adaptive Power Probabilistic Clustering algorithm for optimal cluster head selection. Probability clustering algorithms are employed to determine the prospect of attracting a cluster head. Elliptic Curve Diffie-Hellman (ECDH) and Secure Hashing algorithm 512 (SHA-512) are utilized for secure key exchange and hashing, respectively. Additional features include bit addition, long message redemption value, initialization of hash value, and the integration of Ethereum Smart Contracts (SC) for trusted distributed cross-domain operations. The study investigates the performance of the proposal for cloud-fog computing networks via simulation analysis using Matlab software. This model aims to provide a comprehensive and robust framework for secure and efficient data management in distributed environments. In this context, reliability pertains to the level of assurance and trustworthiness of the data access contro

Based on the analysis of existing wireless sensor networks(WSNs) security vulnerability, combining the characteristics of high encryption efficiency of the symmetric encryption algorithm and high encryption intensity of asymmetric encryption algorithm, a hybrid encryption algorithm based on wireless sensor networks is proposed. Firstly, by grouping plaintext messages, this algorithm uses advanced encryption standard (AES) of symmetric encryption algorithm and elliptic curve encryption (ECC) of asymmetric encryption algorithm to encrypt plaintext blocks, then uses data compression technology to get cipher blocks, and finally connects MAC address and AES key encrypted by ECC to form a complete ciphertext message. Through the description and implementation of the algorithm, the results show that the algorithm can reduce the encryption time, decryption time and total running time complexity without losing security.

This research paper introduces a novel symmetric encryption algorithm that provides the confidentiality security service without leaking enough information about the exact encryption algorithm or other cryptographic parameters to anyone except the legitimate receiver. This is achieved by utilizing a set of sound existing symmetric encryption algorithms, namely, the Advanced encryption Standard,MARS,RC6, Serpent and Twofish. The identity of the algorithm used to secure the current message, along with other cryptographic parameters (e.g. mode of operation, key length), are hidden from anyone except the legitimate receiver. These parameters are shared securely between communicating parties by utilizing some of the symmetric key bits. The cipher suite in addition to the encryption key, changes systematically and securely with every new message, leaving the opponent with no enough information to launch any effective attack. The algorithm performance is tested, and the overall performance is close to the performance of conventional encryption with a delay of about 16.52 CPU Cycles per message. From a security point of view, the possibility of cryptanalysis is diminished significantly, as no party except communicating parties has any knowledge of the cryptographic parameters in use.

In this paper, we proposed a hybrid encryption algorithm in order to solve the security problems on lightweight data on the cloud storage service. This paper first improves the RSA algorithm in the cloud environment by increasing the length of the RSA key to an extent that it can quickly generate big primes. Then, we merge AES and RSA algorithms on the basis of the improved RSA algorithm. This is called a hybrid encryption algorithm which is suitable for security of the lightweight data in cloud storage environment in order to further enhance the confidentiality of data in the cloud. The experimental result shows that the hybrid encryption algorithm has advantages of fast encryption and decryption, more secure, and it is also able to settle the security problems of users' lightweight data in a certain extent.

With the rapid development of electronic information technology, data security issues are becoming increasingly serious. Traditional single cryptographic algorithms cannot meet the increasing demands of security and computational speed. In order to solve the problem of fast and secure transmission of large amounts of data by embedded devices, this paper proposes an improved hybrid encryption algorithm based on national encryption algorithms such as SM2 and SM4. In the implementation methods of algorithms in embedded devices, software hardware collaborative design balances software flexibility and hardware parallelism, which also improves system security and reduces development and maintenance costs. Therefore, this article uses software hardware collaborative design methods to implement hybrid encryption algorithms. In addition, this article also optimizes the hardware of SM2 point multiplication, which can be used in devices with limited hardware resources. The experimental results show that under a 16MHz clock and using the elliptic curve recommended by SM2 on GF (2257), the encryption speed is 4.04ms/time, the decryption speed is 2.96ms/time, and the number of point multiplication is 1685 times per second on Xilinx DDR200T FPGA.

One of the most crucial components of information technology infrastructure in the modern world is cloud data centers. Customers have access to these data centers' infrastructure and software, which enable them to store and process massive amounts of data. However, the security and protection of private data in cloud data centers is a serious problem that needs effective and c solutions. Security and privacy issues exist because cloud computing outsources the processing of sensitive data. Consumer worries about cloud infrastructure security remain, particularly those related to data privacy. A thorough analysis of research efforts in the area of cloud security is the main objective of this study. In order to do this, a variety of models were evaluated, their advantages and disadvantages were identified, and a viable security solution based on symmetric algorithms was put forth. The original text in the proposed solution (hybrid encryption algorithm) is first encrypted using the faster symmetric key method AES, and then its key is encrypted using the faster asymmetric key scheme RSA. This increases efficiency and speed. This method will shorten the time required for data encryption while enhancing its security. The final step was implementing the desired solution in the Eclipse software environment and comparing it against the Blowfish and RSA algorithms. The evaluation's findings indicate that the solution is more advantageous, which has resulted in a nearly two-fold decrease in execution time and a marked increase in throughput when compared to the RSA algorithm. Additionally, the execution time has shrunk, and throughput has been vastly improved compared to the Blowfish method.
