「DES」（Data Encryption Standard）と「AES」（Advanced Encryption Standard）は、どちらも暗号アルゴリズムの名前だ。一見似た名称であり、どちらも共通鍵を用いてデータをブロック（固定長のデータ）単位で暗号化する「共通鍵ブロック暗号」方式に分類される。

In the field of computer technology, some topics are so frequently and fiercely disputed that they almost resemble religious feuds — Mac vs. PC, for instance, or open source vs. proprietary software.

AES is the Advanced Encryption Standard, a standard for cryptography that is used to encrypt data to keep it private. It is a popular cypher, used for many purposes, including the US Government to ...

In the previous blog post, “Embedded Security Using Cryptography”, we looked at how cryptography can be used for securing assets in embedded systems and ensure confidentiality, integrity and ...

AES-256 remains the gold standard for high-stakes data encryption. While other, more lightweight and less-energy-intensive encryption methods do exist, they operate with multiple trade-offs in ...
