I have more bits than the degree of the NTRU polynomial.

For example: $x^{11}-1$
message: Hello (I am using ascii, 8 bits for 1 symbol)
got: 0100100001100101011011000110110001101111.

How should I split up message into blocks? Please answer with example.

You should use hybrid encryption, and NTRU parameters giving you a wide intermediary key. – fgrieu May 31 '14 at 17:25
I suppose the responses to How can I use asymmetric encryption, such as RSA, to encrypt an arbitrary length of plaintext? apply here just as well. – Paŭlo Ebermann Jun 1 '14 at 18:07
