| data encryption | تشفير البيانات (The process of converting readable data (plaintext) into a coded form (ciphertext) to prevent it from being read by an unauthorized party) |
| data encryption key | مفتاح تشفير البيانات (A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data) |
| Data Encryption Standard | مقياس تشفير البيانات (An encryption algorithm that uses a 56-bit key and maps a 64-bit input block to a 64-bit output block. The key appears to be a 64-bit key, but one bit in each of the eight bytes is used for odd parity, resulting in 56 bits of usable key) |
| Triple Data Encryption Standard | مقاييس تشفير البيانات الثلاثية (An encryption algorithm based on the Data Encryption Standard (DES)) |
