| Terminology | Description |
|---|---|
| AES | Advanced Encryption Standard. |
| AAD | Additional Authentication Data. Specifies data that only requires authentication, not encryption or decryption. |
| Block Cipher | Algorithm that operates on fixed length blocks of data, one block at a time. |
| Ciphertext | The result of an encryption performed on a plaintext. |
| CTR | Counter mode. |
| CTS | Ciphertext Stealing. Method of encrypting plaintext using a block cipher without padding the message to a multiple of the block size. |
| DTLS | Datagram Transport Layer Security. |
| EML | Exact Match Lookup. Performs Lookup operation on DDR and produces result which may or may not match based on the lookup. |
| HPS | Hard Processor System. |
| HSSI SS | High Speed Serial Interface Subsystem. |
| GCM | Galois/Counter mode used for symmetric-key block ciphers. |
| ICA | Inline Cryptographic Accelerator. |
| ICV | Integrity check value. |
| IV | Initialization Vector. Continually changing number used in conjunction with a key to encrypt data. |
| Key | A string of bits used within an encryption algorithm for altering data so it appears random. |
| MAC | Message Authentication Code. |
| MAC Security | Media Access Control Security used to protect Ethernet links. |
| MCDMA | Multichannel Direct Memory Access. |
| Memory SS | Memory Subsystem. |
| OSCCA | Office of the State Commercial Cryptographic Administration |
| PCIe SS | PCI Express Subsystem. |
| Plaintext | The result of a decryption performed on a ciphertext. |
| SCA | State Cryptographic Administration. |
| SM4 | Block cipher used in the Chinese National Standard for Wireless LAN. |
| TCAM | Ternary Content-Addressable Memory. |
| Tweak | A string of bits added to the encryption algorithm to mimic random permutation. |
| VSIP | Validation Soft IP. |
| XTS | XEX-based tweaked-code block mode with ciphertext stealing. |
