Research ArticleOpen accessIn the abstractPERFORMANCE ANALYSIS OF IMAGE SECURITY BASED ON ENCRYPTED HYBRID COMPRESSIOND. Ramkumar, I. Jacob RaglendIn this research, we propose an image security scheme using hybrid compression techniques. In this scheme, the data is being provided two-fold security by both encryption stage and hiding stage. The data/message which has to be secured undergoes encryption technique at the initial stage. In this stage, the permutation algorithm is employed which requires a pair of numbers as a … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 26 Apr 2014 · 6,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFICIENT RANKED AND SECURE FILE RETRIEVAL IN CLOUD COMPUTINGJ. Jospin Jeya, E. KannanCloud computing facilitates extremely scalable services that can be consumed over internet. An important aspect of the cloud services is that user data are stored remotely in unknown machines in which users do not posses or manage. Since the data’s are stored remotely, we have to keep in mind that sensitive cloud data have to be encrypted before they are … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 3 Apr 2014 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractTemporal, Delegable and Cheap Update Access Control to Published XML DocumentsWaleed Halboob, Ali Mamat, Ramlan Mahmod, Muhammad Khurram KhanProviding access control for published XML documents on the Web is an important topic. It involves the use of cryptographic techniques, addressing different requirements and, as a result, facing several challenges. Existing solutions still have some weaknesses such as system update cost, number of required secret encryption/decryption keys, size of encrypted document and supporting temporal and delegable access.
