Side Channel Power Analysis of an AES-256 Bootloader
... If the plaintext was known, the Initialization Vector (IV) can be trivially determined once the encryption key is known. With the encryption key, the attacker can decrypt everything except the first 16 bytes; at this ...
AES-256 Encryption in Communication using LabVIEW
... E. Key Expansion and Key extraction: In the AES algorithm, the key expansion module is used for generating round keys for every round. There are two approaches to provide round keys. One is to pre-compute and ...
Securing the Transfer of Confidential Data in Fiscal Devices using Blockchain
... Data security refers to the method of protective knowledge from unauthorized access and knowledge corruption throughout its lifecycle. Data security includes encryption, tokenization, and key management practices that ...
Energy Optimization of Unrolled Block Ciphers using Combinational Checkpointing
... Abstract. Energy consumption of block ciphers is critical in resource constrained devices. Unrolling has been explored in literature as a tech- nique to increase efficiency by eliminating energy spent in loop control ...
