12description: |
13 The Inside Secure SafeXcel EIP-93 is a cryptographic engine IP block
14 integrated in varios devices with very different and generic name from
15 PKTE to simply vendor+EIP93. The real IP under the hood is actually
16 developed by Inside Secure and given to license to vendors.
17
18 The IP block is sold with different model based on what feature are
19 needed and are identified with the final letter. Each letter correspond
20 to a specific set of feature and multiple letter reflect the sum of the
21 feature set.
22
23 EIP-93 models:
24 - EIP-93i: (basic) DES/Triple DES, AES, PRNG, IPsec ESP, SRTP, SHA1
25 - EIP-93ie: i + SHA224/256, AES-192/256
26 - EIP-93is: i + SSL/DTLS/DTLS, MD5, ARC4
27 - EIP-93ies: i + e + s
28 - EIP-93iw: i + AES-XCB-MAC, AES-CCM
