| 发明名称 | Apparatus and method for providing security service | ||
| 摘要 | An apparatus and method for providing a security service are provided. The apparatus for providing a security service includes a first block cipher and a second block cipher. The second block cipher is independent of the first block cipher, and is configured to be used as a random number generator when the first block cipher is used to perform encryption/decryption, and to be used to perform encryption/decryption when the first block cipher is used as a random number generator. | ||

| 主权项 | 1. An apparatus for providing a security service, the apparatus executed by at least one processor and comprising: at least one hardware processor; a first block cipher loaded on the at least one processor; and a second block cipher loaded on the at least one processor and configured to be independent of the first block cipher, wherein the second block cipher is configured to be used as a random number generator while the first block cipher is used to perform encryption/decryption, or the second block cipher is configured to perform encryption/decryption while the first block cipher is used as the random number generator, wherein one of the first and second block ciphers operating as the random number generator provides a generated random number to another one of the first and second block ciphers performing encryption/decryption, and wherein the generated random number is used to mask intermediate results of the encryption/decryption. | ||
