Abstract

Cloud computing is a model for using computer resources and technologies to provide services such as storage and applications. Users can access and use the cloud computing services without the need to acquire knowledge, expertise or even administration of infrastructures that support these services. Cloud computing can be a general concept which includes software services and other modern technological functionality in the information technology world. Since cloud computing shares distributed resources through the Internet and intranet in the exposed environment, security is therefore an important issue. Cryptography is one of the common practical choices for cloud computing developers. It can offer a high level of security. However, cryptanalysis shows some weaknesses in block cipher modes, such as parallelization for Cipher Block Chaining (CBC) mode. This paper will explore the security issues of the standard block cipher modes of operation as well as in cloud computing. In addition, a new mode of encryption called the parallel encryption mode will be presented. In this mode each cipher block makes use of the characteristics of the entire file instead of just the previous cipher block. Therefore, if any single plaintext block is changed, all the cipher blocks will be changed. This mode offers high levels of security, integrity and enhances the performance of the block cipher in terms of speed as compared to standard CBC mode.
