IPP cryptography performance problem

hello:

      I'm using IPP cryptography API  to develop program! do you have any documents about   optimization cryptography API  performace comparing with not  optimization cryptography  algorithem?

     Because ,when I was testing the RSA algorithem , I find the intel IPP RSA  algorithem performance wasn't well with openssl sorce code! If you have any testing report or document abot  cryptography algorithem optimization compare with not optimization ,can you send to me ? thank you!

Hi sunny,

Could you provide more information including OpenSSL version, IPP crypto version, RSA key size? which CPU you are using (SIMD)? How the performance you tested like?

If you have more question, please submit your request through Intel Online Service Center, and paste your information there. Thanks.

Best regards,
Fiona

hello Fiona:

       the openssl  version is :1.0.01;

       the intel ipp cp name and version is :Name:ippCP AVX2 (l9),Version: 2017.0.3 (r55431) _2017.0.3.55431

       the intel CPU is :E3-1225

       the following is testing  performance data between openssl and intel ipp cp lib:

   

Generate key pair:

Key length

(bits)

Openssl

( pairs/s)

Intel ipp

(pairs/s)

1024

59

35

2048

RSA encryption and decryption:

function

Key length

(bit)

Data

(bytes)

Openssl 

(times/s)

Intel ipp

(times/s)

ippsRSA_Encrypt

1024

128

104341

ippsRSA_Decrypt

RSA sign and verify:

function

Key length

Openssl 

(times/s)

Intel ipp

ippsRSASign_PSS

   from the datasheet, we can find intel RSA key pair generate isn't well with openssl, otherwise ippsRSA_Encrypt and ippsRSAVerify_PSS alse aren't  well withe opensll!

hello:

    I haven't received any respond from your development team about this question for such many days. Can you tell me when they will answer me about my question? I'm waiting for your respond to reslove my development program. Sincerely, hope will be so fast ,thank you very much!

   Otherwise ,can you send me about your testing performance report about RSA algorithem by your development team? thanks!
