EKMS (Electronic Key Management System)
EKMS (Electronic Key Management System): A system designed to handle the generation, distribution, accounting, and destruction of cryptographic keys. As part of a robust encryption strategy, the EKMS ensures that the necessary cryptographic keys are available when needed and are kept secure at all times to prevent unauthorized access to encrypted data.
Enumeration
Enumeration: A process used in the reconnaissance or pre-attack phase where a potential attacker interacts with a system to gather information that could be useful for exploiting it. This may involve determining a user’s valid email address, network resources, shared directories, IP addresses in use, or even detailed user account information in certain circumstances.
El Gamal Algorithm
El Gamal Algorithm: A public key cryptosystem based on the Diffie-Hellman key exchange. It was developed by Taher ElGamal in 1985 and is used for digital signatures, key agreements, and encryption. The El Gamal encryption system is an alternative to the RSA algorithm and relies on the difficulty of calculating discrete logarithms for providing security. […]
Ephemeral Key
Ephemeral Key: A cryptographic key that is used only once or for a brief period of time before being discarded. It is typically employed in secure communications to ensure the confidentiality and integrity of each individual session. The use of ephemeral keys enhances security by ensuring that even if a key is compromised, it can’t […]
Electronic Code Book (ECB) Mode
Electronic Code Book (ECB) Mode: Electronic Code Book (ECB) Mode is the simplest form of block cipher encryption where each block of plaintext is encrypted independently. Its main weakness lies in not hiding data patterns well, as identical plaintext blocks produce identical ciphertext blocks. This predictability can lead to security vulnerabilities, making ECBs unsuitable for […]
Documentary Evidence
Documentary Evidence: The recorded, tangible, or digital information that can be used as evidence in an investigation or audit. This could include written contracts, emails, log files, or transaction records. In the context of digital systems, this often means logs, system messages, and other digitally recorded actions that could serve as proof of an event […]
