Abstract

Recently data sharing through the cloud is widely used and becoming a trend. But protecting data confidentiality and integrity is essential. Data confidentiality and integrity are maintained using cryptography. However, since it cannot ensure that the data hasn't been altered, there is still a trust issue. The proxy re-encryption (PRE) technique was presented as a solution to this. It includes encrypting the data twice, allowing one to determine whether or not it has been altered. The PRE system is also prone to attacks that forge re-encryption keys. Here the data is encrypted twice so that the data can be checked whether it is modified or not. But the PRE system is prone to the abuse of re-encryption keys. Therefore, accountable proxy re-encryption (APRE) is proposed. Here, if the data is altered by proxy, the system will detect whether proxy is malicious or the delegator is trying to frame proxy as malicious. Also, the authors extend the algorithm and implemented base64 encoding and decoding. This prevents many passive cyber attacks.
