  • DEVICE AND METHOD OF SECURE DECRYPTION BY VIRTUALIZATION AND TRANSLATION OF PHYSICAL ENCRYPTION KEYS
    Publication number: 20230333992
    Abstract: Example implementations include a system of secure decryption by virtualization and translation of physical encryption keys, the system having a key translation memory operable to store at least one physical mapping address corresponding to at least one virtual key address, a physical key memory operable to store at least one physical encryption key at a physical memory address thereof; and a key security engine operable generate at least one key address translation index, obtain, from the key translation memory, the physical mapping address based on the key address translation index and the virtual key address, and retrieve, from the physical key memory, the physical encryption key stored at the physical memory address.
