Title:
TECHNIQUES AND DEVICES FOR CONFIGURABLE MEMORY ENCRYPTION AND AUTHENTICATION
Document Type and Number:
WIPO Patent Application WO/2023/164167
Kind Code:
A3
Abstract:
Disclosed systems and techniques involve flexible encryption, decryption, retrieval, and authentication of data. The systems may include a cryptographic processor that, in a first selectable mode of operation is configured to identify plaintext blocks, generate encrypted ciphertext blocks, process sequentially the ciphertext blocks to obtain an authentication value, encrypt the authentication value, and store the ciphertext blocks and an authentication tag, obtained based on the encrypted authentication value. In a second selectable mode, the cryptographic processor may perform ciphertext block encryption but forgo obtaining the authentication value.
