Dear All,
Hello. My customer got the HDMI HDCP1.4 sample application for L3.0.35.
i.MX6DQ has many encryption algorithms in CAAM (like a DES(64bit), 3DES(128bit), AES(256bit), RC4(128bit)).
What kind of algorithms is use in HDCP1.4 application?
Best Regards,
Keita
Hello,
The i.MX6 HDMI has own HDCP Encryption Engine. The CAAM is used to
encrypt / decrypt keys, stored in i.MX6 OTP. Please refer to "Android HDCP2.x
User's Guide" of Android documentation.
Have a great day,
Yuri

Hi Yuri,
Thank you for your prompt reply.
Sorry. I update my question.
[Question]
> The i.MX6 HDMI has own HDCP Encryption Engine.
What type of algorithm is used in this HDCP Encryption Engine in HDMI block? (Dedicated algorithm for HDCP1.4? AES? DES?)
I think that 56 bit dedicated algorithm for HDCP1.4.

Keita
