摘要

云计算技术包含各种重要的理想限制,如安全性、责任、政府监视、电信容量、匿名性和隐私性。密文技术的使用被认为是执行加密过程的一种理想技术,以解决向云中共享的数据授予安全性的问题。类似地,云计算系统中的多租户体系结构为服务提供商和最终用户都带来了好处,它向多个租户(即)用户共享一个公共云平台,并且通过实现拟议的体系结构也可以计算合适的资源。因此,在本研究工作中,集成了密文多租户的概念,为云环境中共享的数据提供增强的安全性。为此,本文提出了一种基于Diffee Hellman算法的改进椭圆曲线密码算法(MECC),该算法通过交替密钥生成提高了加密的安全性。对加密、解密、上传和下载时间进行了计算,与现有算法相比,本文提出的算法在所有这些措施上所花费的时间都更少。改进后的ECC具有内存少、运算性能高、密钥尺寸小、密钥生成过程快、有效节约资源等特点,可以获得较高的效率。所提出的MECC系统的加密时间为51ms,密钥长度为4096位,而现有方法的加密时间为92ms。同样,密钥长度为4096位时,所提出模型的解密时间为159ms。因此,与现有的AES、Blow Fish和Two Fish相比,该系统将密文密钥大小减少了836KB。此外,与现有方法相比,密钥生成时间(35 s)似乎也大大缩短。这些陈述表明,所提出的系统在密钥生成时间、加密和解密时间以及计算复杂性方面都优于目前的方法。

Modified ECC for Secure Data Transfer in Multi-Tenant Cloud Computing
Cloud computing technologies comprise various kinds of significant desirable constrains such as security, liability, government surveillance, telecommunications capacity, anonymity and privacy. The usage of cipher text technology is considered as a desired technique for performing the process of encryption in order to solve the issue of granting security to the data that are shared in the cloud. Similarly, the architecture of multi-tenant in the cloud computing system grants benefits to both the service providers and end-users which shares a common cloud platform to multiple tenants (i.e.) users and suitable resources are also computed by implementing proposed architecture. Therefore in this research work, the concept of cipher text multi-tenant are integrated for providing enhanced security to the data shared in the cloud environment. Hence a Modified Elliptic Curve Cryptography (MECC) based on Diffee Hellman algorithm is proposed in this research paper which provides enhanced security using alternate key generation. The encryption, decryption, upload and download time are calculated and it is concluded that the algorithm that is proposed in this research paper consumes less time for all these measures when comparing with other existing algorithms. Characteristics like less memory, high operational performance, small sized keys and rapid key generation process, and effective resource savings enable the modified ECC to obtain high efficiency. The encryption time of the proposed MECC system was 51ms with the key length 4096 bits, whereas existing method had 92ms as encryption time. Likewise With the key length of 4096 bits, the decryption time for the proposed model was 159ms. Accordingly the proposed system has reduced cipher text key size of 836KB when compared with the existing AES, Blow Fish, and Two Fish. Additionally, the key generation time (35 s) also seems to be considerably reduced when compared with the existing methods. These statements reveal that the proposed system outshine the state of art methods in terms of key generation time, encryption and decryption time and computational complexity.
