REVIEW ON SECURITY ENHANCEMENT FOR CLOUD DATA STORAGE USING THRESHOLD CRYPTOGRAPHY
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 10
Abstract
In organizations and institutions Cloud computing is very popular because it provides storage and computing services at very low cost. However, for ensuring the confidentiality, integrity and access control of the data it also introduces new challenges. Some approaches are given to ensure these security requirements but they are lacked in some ways such as destruction of data confidentiality due to collusion attack and heavy computation (due to large no keys). We propose a scheme that uses threshold cryptography To address these issues in which data owner divides users in groups and gives single key to every user group for decryption of data and, each user in the group shares parts of the key. In this paper, to control the access we use capability list. This scheme provides the strong data confidentiality as well as reduces the number of keys.
