Key Derivation: A Dynamic PBKDF2 Model for Modern Cryptographic Systems [PDF]

Cryptography
Traditional key derivation techniques, including the widely adopted PBKDF2, operate with static parameters that do not account for contextual factors such as device capabilities, data sensitivity, or password strength.

On the Weaknesses of PBKDF2

Lecture Notes in Computer Science, 2015
Password-based key derivation functions are of particular interest in cryptography because they (a) input a password/passphrase (which usually is short and lacks enough entropy) and derive a cryptographic key; (b) slow down brute force and dictionary attacks as much as possible. In PKCS#5 [17], RSA Laboratories described a password based key derivation

Examining PBKDF2 security margin—Case study of LUKS

Journal of Information Security and Applications, 2019
Abstract Passwords are widely used to protect our sensitive information or to gain access to specific resources. They should be changed frequently and be strong enough to prevent well-known attacks. Unfortunately, user-chosen passwords are usually short and lack sufficient entropy.
