What is LP Trusted Crypto (LTC)?

yasuhikokoumoto — Wed, 24 Jun 2015 02:10:59 GMT

Hello,

I am very interested in the LP Trusted Crypto (of K8x?).

I would like to know much more than describe in BRKINETISSECSOLS (Kinetis MCUs Security an integrity Solution Brochure).

Are there any good materials to learn it?

Thank you and best regards,

Yasuhiko Koumoto.

Cryptographic co-processor for AES, DES and public key cryptography

Combines multiple cryptographic hardware accelerator engines, which share common registers.
AES128 and AES256 support; and support for
- Confidentiality (ECB, CBC, CTR, OFB, CFB128)
- Authenticated confidentiality (CCM)
- Authentication (XCBC-MAC, CMAC)
Single- and triple-DES functionality and ECB, CBC, CFB, and OFB modes as well as key parity checking in compliance with the DES specification.
Public key hardware accelerator capable of performing a number of different operations used in public-key cryptography, including modular arithmetic functions such as addition, subtraction, multiplication, exponentiation, reduction, and inversion, as well as elliptic curve functions for point addition, point doubling, and point multiplication.
Deployed in Kinetis K8x MCUs.

At present we do not have much more information and after the K8 mass production, the LTC detail will been available with the SDK.

Hello Fang Li,

thank you for your reply.

I understood well.

By the way, what does 'LP' stand for?

Is it Low Power?

Best regards,
