A computerized system configured for encrypting several units, wherein each of the units comprises data, the system comprising:
- an initialization vectors generating component for generating initialization vectors, or IVs, for the units;
- a memory, coupled to the initialization vectors generating component, configured to store the generated IVs;
- and
- one or more of an encryption and a decryption component coupled to the memory to access, for each unit of the several units, a stored IV corresponding to the unit and encrypt or decrypt the unit according to the accessed IV and an encryption key.
