Recently, the requirement of database encryption has increased. But many companies are not willing to adopt the use of encryption in their existing DBs due to the degradation in performance. In this paper, we proposed and implemented a high speed database encryption model using Graphics Processing Units(GPU) that can perform parallel data processing. As a result, there was a performance improvement of about 40% to 60% compared to the CPU case. We expect our paper can be used to increase the encryption performance of database.

database encryption is essential for cloud database systems. For a large database, decryption could take a lot of computational time. Therefore, verifying an encryption that contains a correct plaintext without decryption becomes significant for a large database system. Plaintext-checkable encryption (PCE) is a potential tool for such database systems, which is first proposed by Canard et al. in CT-RSA 2012. Although the generic PCE in the random oracle model has been studied intensively, the generic PCE in the standard model and its efficient implementation are still challenging problems. This paper presents the first generic PCE in the standard model using smooth projective hash function (SPHF) and prove its s-priv1-cca security, which is independent of current unlink security. Based on the instantiated SPHF from DDH assumption, we obtain the most efficient PCE in the standard model, without any pairing operation. Finally, we improve two existing generic constructions in the random oracle model so that they are secure under chosen ciphertext attack. (C) 2017 Elsevier Inc. All rights reserved.

At present, there are many research achievements in the field of block cipher. Especially, the AES (Advanced encryption Standard) algorithm should be considered the excellent representative of all the researches. When the data encryption standard was replaced by the advanced encryption standard, the whole world was putting light on the AES algorithm. Some research showed that the AES algorithm can be implemented fastly by shifting, xor and looking up tables. In this paper, we studied the implement of the fast AES algorithm in database system because database encryption technology was paid more attention. Through testing, we can see that the use of fast AES algorithm on the database system has little effect upon the efficiency of the database.

With the popularity of mobile terminals in our life, Including education, entertainment, industry and other fields. People have been thinking about it, initially, People want enterprise-database for the purpose of processing large amounts of data to be used directly embedded devices, however, because their resources are extremely limited. So this idea had to be abandoned, only use embedded database design. Considering the fact that most of the embedded database management system (EDBMS) are do not perfect in the information security of the data, We studied encryption principle of the embedded database management system (EDBMS) on the basis of the practical application, and implemented the system requirements such like real-time performance, high efficiency and high reliability. Finally we designed and realize the function of database encryption based on the embedded database

With the rapid development of computer network technology, more and more units and individuals share abundant data resources, and information security has become the primary problem to be solved by network information systems. The database management system comes with a basic security technology strategy, which can solve common database security requirements. However, for some special data security applications, the security technology strategy of the database itself cannot meet the requirements, which requires data encryption. Processing data encryption is the core content of information security research, and database encryption is an important means to improve database security. This paper studies the design of embedded network database system based on BS structure.

Efficient database encryption Scheme for database-as-a-Service Environment

INTERNATIONAL JOURNAL OF SECURITY AND ITS APPLICATIONS 2015年第5期9卷 195-203页

Computing-as-a-service is gaining ground. Clients may use the service without purchasing the system supporting the service. database-as-a-Service (DBaaS) is an important area of computing-as-a-service. DBaaS allows clients to use an expensive database management system without purchasing it. In a DBaaS environment, database Tables are stored on servers belonging to a service provider, and hence, they must be encrypted in order to ensure data confidentiality. However, the encryption introduces performance degradation in the execution of queries over encrypted data. The execution of range queries, in particular, undergoes severe performance degradation. Several encryption schemes to alleviate this problem have been proposed. However, most of these schemes leak other information in addition to order information. In this study, a new database encryption scheme for DBaaS is proposed. The proposed scheme enables the execution of range queries without severe performance degradation and without leakage of information other than order information.

A Secure Scheme of Key Management for database encryption

A Secure Scheme of Key Management for Database Encryption

2011 2nd Asia-Pacific Conference on Wearable Computing Systems

作者： Xiao-han Sun Department of Computer Science Weinan Teachers University

Key management is the crucial technique for database encryption. The keys to encryt and decrypt the secret data are generated and administered by the creators who create the secret data. Anyone who makes a request on the secret data has to register himself in a certificate authority and get his public key certificate. The requestor sends his request on the secret data to the database administrator and the creator of the secret data. The database administrator verifies the identity of the requestor and forwards the request to the creator. After the creator compares the two requests, he sends the keys to the requestor. The schmen is more safe because the keys is administered by different creators, the secret data saved in database is encrypted with the creator's writing keys and the database administrator's ephemeral keys, the creators' reading and writing keys must be changed periodically and the administrator's ephemeral must be changed after every writing operation.
