comment What is the most light-weight symmetric cipher thats still usefull?
What are your actual limitations? The answer(s) to your question greatly depend on your platform, and how limited your ROM and RAM are.

comment Where I can find a list of certified software / hardware RNGs compliant to NIST SP 800-22?
According to this page, NIST certifies four DRBG techniques, and no NRBGs. It doesn't seem that they've explicitly certified any implementation.

comment CCA-attack is possible in RSA, but how the decryption key $d$ is known to anyone
Are you talking about Bleichenbacher's ACCA attack? My understanding is that it's a padding oracle attack against PKCS#1, which inherently affects RSA, rather than an attack against RSA itself.

comment Can I crack an AES string if I have all these parameters?
@Matthew ... and verify that the result is correct by doing statistical analysis. Remember that AES decryption with incorrect keys just gets you a bunch of incorrect plaintext bytes.

comment Galois field step in XEX mode
Surely $2^n$ over $GF(2^{128})$ is equal to $2^n\ mod\ 2^{128}$?

@mikeazo If you look, that question you linked was asked by me.
