    Self Destruction of Cipher Text in Cloud Storage
    (2016-12-19T12:51:10Z) Rekha, SN
    Cloud Computing is the one which is increased rapidly for the storage of the sensitive private information by wide range of organizations. The cloud technology provides one of the most important emerging technology, it has the way in which the organizations using the technologies and techniques which makes them to easily available for the user anywhere any time with a flexible costs. The cloud storage and obtaining has popularity in the cloud services like pay-per-use and many other. The user’s sensitive information which is stored in the cloud like secret, important information, private sensitive or public can be stored. Cloud service like pay-per-use scheme helps users to utilize the storage network which attracts the business and IT people to use the cloud. Since the cloud is adaptable for any working eenvironmet, it is more prone to attacks by the third parties. Whatever methods used to secure the data in the cloud may be hacked by the attackers and can get the sensitive data which is stored. The unknown parties can harm the data which is stored in the cloud makes a great loss for the users. To avoid such problems many techniques have been introduced but they have one or the other disadvantage which can be harmed for the data stored. The system should be more reliable, redundant and secure to store the information in the cloud. To secure the data as of now, users are preferring the front end techniques with some attributes, user id’s, passwords and some keys generated which may not be more secure. The hackers may easily guess the passwords and they may decode the keys used to hack the information. So security at both front end as well as the middle end is very important to avoid hacking. Here a proposed system focuses on both front as well as middle end is introduced which provides more security. The methods used are timestamp, attribute based encryption for self-destruction of the cipher text in the cloud, HMAC coding and also advanced encryption standard algorithm for encryption and decryption. The self-destruction scheme introduced for encrypting data with AES keys and decryption keys by the users. The KP_TSABE will solve some of the important security issues by providing users authentication and authorization and also secured access control during the storage of data.
