摘要： A block cipher is provided that secures data by encrypting it based on the memory address where it is to be stored. When encrypting data for storage in the memory address, the memory address is encrypted in a first plurality of block cipher rounds. Data round keys are generated using information from the first plurality of block cipher rounds. Data to be stored is combined with the encrypted memory address and encrypted in a second plurality of block cipher rounds using the data round keys. The encrypted data is then stored in the memory location. When decrypting data, the memory address is again encrypted as before while the encrypted stored data is decrypted in a second plurality of the block cipher rounds using the data round keys to obtain a partially decrypted data. The partially decrypted data is combined with the encrypted memory address to obtain fully decrypted data.
摘要翻译：提供了一种分组密码，其通过基于要存储的存储器地址对其进行加密来保护数据。当将存储在存储器地址中的数据进行加密时，存储器地址以第一多个块密码循环加密。使用来自第一多个块密码轮的信息来生成数据循环密钥。要存储的数据与加密的存储器地址组合，并使用数据循环密钥在第二多个块密码轮中进行加密。然后将加密的数据存储在存储器位置。当解密数据时，如先前一样再次加密存储器地址，同时使用数据循环密钥在第二多个块密码轮中对加密的存储数据进行解密以获得部分解密的数据。部分解密的数据与加密的存储器地址组合以获得完全解密的数据。
