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
