Cipherbase = Encrypt(Database)Arvind Arasu
engine (SQL Server) with lightweight processing over encrypted data that is performed in secure hardware. Cipherbase has the smallest trusted computing base (TCB) among comparable systems and provides significant benefits over the state-of-the-art in terms of security, performance, and fu...
The Cipherbase system incorporates customized trusted hardware, extending Microsoft’s SQL Server for efficient execution of queries using both secure hardware and commodity servers. This paper presents the design of the Cipherbase secure hardware and its implementation using FPGAs. Furthermore, this ...

Cipher类位于javax.crypto包下,声明为 public class Cipher extends Object 此类为加密和解密提供密码功能。它构成了 Java Cryptographic Extension (JCE) 框架的核心。 为创建 Cipher 对象,应用程序调用 Cipher 的 getInstance 方法并将所请求转换 的名称传递给它。还可以指定提供者的名称(可选)。
()); SecretKey key = SecretKeyFactory.getInstance("DES").generateSecret(keySpec); Cipher decipher = Cipher.getInstance(key.getAlgorithm()); decipher.init(Cipher.DECRYPT_MODE, key); // Decode base64 to get bytes byte[] dec = Base64.getDecoder().decode(msg.getBytes("UTF-8")); //...
CiphertextCryptanalysis Cryptanalysis is easy if you know your text is enciphered with Base64 - just run it through the decoder above. I have seen examples where it has been encoded multiple times - I had to decode it about 6 times to get to plain English.To identify whether you have a...
