dc.description.abstract | Cryptography is one of the most popular methods for protecting data stored in storage devices such as solid-state drives (SSDs). To maintain integrity of data, one of the popular techniques is that all incoming data are encrypted before they are stored, however, in this technique, the encryption overhead is non-negligible and it can increase I/O service time. In order to mitigate the negative performance impact caused by the data encryption, a write buffer can be used to hide the long latency by encryption. Using the write buffer, incoming unencrypted data can be immediately returned as soon as they are written in the buffer. They will get encrypted and synchronized with flash memory. However, if the write buffer itself is not encrypted, unencrypted secret data might leak through this insecure write buffer. On the other hand, if the entire write buffer is fully encrypted, it incurs significant performance overhead. To address this problem, we propose an on-chip access control memory (ACM) and presents a fast encrypted SSD, called FESSD that implements a secure write buffering mechanism using the ACM. The ACM does not require a memory-level full encryption mechanism, thus not only solving the unencrypted data leaking problem, but also offering relatively fast I/O service. Our simu | - |
