| comp., MS | data encryption key | データ暗号化キー (A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data) |
| comp., MS | encryption key | 暗号化キー (A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data) |
| comp. | n encryption key | 暗号キー |
| comp., MS | full volume encryption key | フルボリューム暗号化キー (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. | n public key encryption | 公開鍵暗号 |
| comp., MS | secret key encryption | 秘密キー暗号化 (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) |
| comp. | n shared key encryption | 共有鍵暗号方式 |
