| description: | |
| The Inside Secure SafeXcel EIP-93 is a cryptographic engine IP block |
| integrated in varios devices with very different and generic name from |
| PKTE to simply vendor+EIP93. The real IP under the hood is actually |
| developed by Inside Secure and given to license to vendors. |
| |
| The IP block is sold with different model based on what feature are |
| needed and are identified with the final letter. Each letter correspond |
| to a specific set of feature and multiple letter reflect the sum of the |
| feature set. |
| |
| EIP-93 models: |
| - EIP-93i: (basic) DES/Triple DES, AES, PRNG, IPsec ESP, SRTP, SHA1 |
| - EIP-93ie: i + SHA224/256, AES-192/256 |
| - EIP-93is: i + SSL/DTLS/DTLS, MD5, ARC4 |
| - EIP-93ies: i + e + s |
| - EIP-93iw: i + AES-XCB-MAC, AES-CCM |
