Research ArticleOpen accessIn the abstractCERTIFICATE AUTHORITY SCHEMES USING ELLIPTIC CURVE CRYPTOGRAPHY, RSA AND THEIR VARIANTS-SIMULATION USING NS2S. Shivkumar, G. UmamaheswariA PKI (public key infrastructure) enables users of a basically unsecure public network to securely and privately exchange data through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority. The public key infrastructure provides for a digital certificate that can identify an individual or an organization and directory services … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 18 Dec 2013 · 7,379 accessesView PDFCite
Research ArticleOpen accessIn the abstractPRESERVATION OF THE PRIVACY FOR MULTIPLE CUSTODIAN SYSTEMS WITH RULE SHARINGB. Murugeshwari, C. Jaya Kumar, K. SarukesiThe aim of the research work is to mine the data set available with each custodian in a semi honest model, securely without disclosure of any data amongst various custodians involved. No custodian discloses any information. In the proposed scheme in order to reduce the computational complexity, the data partitioning has been done in the horizontal way. The proposed research … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced RSACRT for Energy Efficient Authentication to Wireless Sensor Networks SecurityP. Kalyani, C.
