EKM

Encryption Key Management. A system whereby encryption

keys are generated, stored, protected, transferred, loaded, and

used.

encryption The conversion of data into a cipher. A key is required to

encrypt and decrypt the data. Encryption provides protection

from persons or software that attempt to access the data without

the key.

Internet Protocol. The method or protocol by which data is

transmitted from one computer (or host) to another over the

Internet using a system of addresses and gateways.

JCE

Java Cryptography Extension.

JCEKS Java Cryptography Extension Keystore.

keystore

A database of private keys and their associated digital

certificate chains used to authenticate the corresponding public

keys.

library managed encryption (LME)

A system of encryption whereby the

library manages the interaction with the encryption-capable tape

drive. LME does not require any ISV support and is transparent

to the application. Q-EKM works with library managed

encryption.

private key

One key in an asymmetric key pair, typically used for

decryption. Q-EKM uses private keys to unwrap protected AES

data keys prior to decryption.

public key One key in an asymmetric key pair, typically used for

encryption. Q-EKM uses public keys to wrap (protect) AES data

keys prior to storing them on the tape cartridge.

Q-EKM

Quantum Encryption Key Manager. A Java application that

handles encryption key management (EKM) via Quantum’s tape

libraries.
