Encryption is the process of converting readable data, known as plaintext, into a jumbled string of data called ciphertext. Encryption algorithms use mathematical operations to scrabble data, making ...

Many embedded systems depend on obscurity to achieve security. We often design systems to download unsigned or unencrypted firmware upgrades or store unencrypted user data, a practice we justify ...

Device security requires designers to secure their algorithms, not only against direct attacks on the input and output, but also against side-channel attacks. This requirement is especially notable ...
