| comp., MS | data encryption key | 資料加密金鑰 (A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data) |
| comp., MS | encryption key | 加密金鑰 (A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data) |
| comp., MS | full volume encryption key | 完整磁碟區加密金鑰 (The algorithm-specific key that is used to encrypt (and optionally, diffuse) data on disk sectors. Currently, this key can be either 128 bits or 256 bits advanced encryption standard (AES). The default encryption algorithm that BitLocker Drive Encryption uses is AES 128 bit with diffuser) |
| comp., MS | public key encryption | 公開金鑰加密 (A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it) |
| comp., MS | secret key encryption | 祕密金鑰加密 (An encryption algorithm that requires the same secret key to be used for both encryption and decryption. Because of its speed, symmetric encryption is typically used when a message sender needs to encrypt large amounts of data) |
