Hybrid cryptosystem with hierarchical private key
Stelian Flonta, Liviu Cristian Miclea, Iulia Adina Ştefan · 2012
The access to protected information is allowed based on the agent access level inside the security system. The management for such systems is made using an interdependent private keys domain, such keys being organized on access levels. The decryption speed is established by the combination of a symmetric encryption system with an asymmetric system. The use of the mathematical model describing elliptical curves increases the security by reducing the needed memory resources.
