Dear,

I'm currently modifying tz_vmm to use openssl (librcrypto) to generate RSA key pair on i.mx53 QSB.

(That is, RSA key pair is generated inside the Secure World.)

Whenever I try to execute the following code, the error occurs.

The source code in tz_vmm (main.cc)

===========================================================

/* key pair generation */

int generate_keypair(){

int keylen;

char *pem_key;

BIGNUM *e=NULL;

keypair = RSA_new();

e = BN_new();

BN_set_word(e, 65537);

if (!RSA_generate_key_ex(keypair, 2048, e, NULL))

PERR("failed to generate key pair");

/* the big number is no longer used */

BN_free(e);

e = NULL;

/* To get the C-string PEM form: */

BIO *pub = BIO_new(BIO_s_mem());

PEM_write_bio_RSAPublicKey(pub, keypair);

keylen = BIO_pending(pub);

pem_key = (char*)malloc(keylen+1);

BIO_read(pub, pem_key, keylen);

pem_key[keylen+1] = '\0';

BIO_free_all(pub);

return keylen;

}

The error code (imx53 QSB)

============================================================

[init -> tz_vmm] read_rtc: rtc not configured, returning 0

[init -> tz_vmm] no plugin found for fcntl(2)

[init -> tz_vmm] no plugin found for write(2)

[init -> tz_vmm] failed to generate key pair

What should I do to fix up this error?

Any comment is welcome.

I'm looking forward to your kind response.

My Best Regards,

Jaemin Park
