RECENT BLOG NEWS

In addition to ongoing support for MPLAB Harmony,  wolfSSL has updated its support for Microchip Libraries for Applications (MLA). Using wolfSSL`s embedded SSL/TLS libraries we created an MLA TCP/IP demo using the PIC32 Ethernet Starter Kit, which enables SMTP and HTTPS over SSL/TLS. For access to this demo contact us today at facts@wolfssl.com.

If you are using Microchip’s MLA on any of the supported platforms (PIC16, PIC18, PIC24, dsPIC33, or PIC32) and looking for an embedded TLS solution, or have questions, please contact our support team at support@wolfssl.com, we would be more than happy to support your efforts!

@wolfSSL has been collaborating with @TXInstruments for some time to provide ongoing hardware encryption support for your #IoT projects! Hardware support for the following algorithms is available in the #wolfSSL #embedded #TLS #SSL library when building with #TIRTOS for the #TivaC(PDF) micro controller.

AES
CCM
DES3
MD5
SHA
SHA-224
SHA-256

For instructions on building wolfSSL on TIRTOS, the following guide is very useful! Also included in the guide are details on setting up a TLS example server!

The wolfSSL embedded SSL/TLS library and wolfCrypt embedded crypto engine have been integrated into the Atmel ATECC508A crypto element, adding support for ECC hardware acceleration and protected private key storage on the ATECC508A.
Using wolfSSL, ATECC508A users can benefit from both increased ECC performance and secure key storage, thus hardening their TLS connections.  The wolfCrypt ATECC508A port adds:

+ wolfCrypt support for ECC hardware acceleration using the ATECC508A.  The new defines for this port are WOLFSSL_ATMEL and WOLFSSL_ATECC508A
+ New public key callback for Pre Master Secret

For more complete details please visit the wolfSSL Atmel webpage. The code can be downloaded directly from wolfSSL’s “More Downloads” page, with the title “Atmel_ATECC508_Demos.zip”.

Each year we like to document, review, and reflect on our progress, the details of which are below.  As most of our consumers know, we’ve been diligent in the squashing of bugs, our testing, and the addition of features.

We made a world of progress in 2016, but these accomplishments stand out:

1. We’ve continued to make significant enhancements to our unrivaled cryptography test rig,
2. We’ve added support for a number of secure enclaves, and
3. We added to our already long list of hardware assisted cryptography methods, and finally,
4. We’ve added a number of new environments and algo’s to our FIPS-140 certificate.
5. We also crossed over to securing over 2 Billion connections

All in all, we’re pretty happy with what we’ve done!

Now let’s look forward into 2017!  You can expect us to release a string of TLS 1.3 based enhancements.  Our TLS 1.3 client is currently in alpha, and will make progress quickly.  Shout out and many thanks to the IETF TLS WG for making systematic progress on the new protocol.

You can also expect us to make a lot of progress on supporting additional secure enclaves.  They are now a fundamental requirement for professional IoT designs.  The same is true for the server side of the connection, where clunky HSM’s will be replaced by Intel’s SGX.

See below for all of the engaging details!

wolfSSL is currently collaborating with the “Revolutionary Internet of Things Operating System” (RIOT-OS) community to bring security to the embedded IoT devices supported by RIOT OS.

wolfSSL has some alpha examples that build and run on the “native” board with plans to add additional platform support on demand. If you would like to see specific device support or speed up this integration effort send us a note support@wolfssl.com!

PKCS12 is commonly used when solving the problem of securely transporting a private key and certificate pair by file. wolfSSL has recently added PKCS12 parsing capabilities to the wolfSSL embedded TLS/SSL library giving the ability to securely load a certificate along with its private key from .p12 files.

PKCS12 files contain internal storage “containers”, called “SafeBags”. Each SafeBag may be individually encrypted and signed. Specific SafeBags are set aside to store certificates, private keys and CRLs however there are additional SafeBags provided to store additional data as required by the user.

For more information about parsing PKCS12 files using wolfSSL contact us at facts@wolfssl.com

#Crypto #Hardware #Performance

We now support the Intel QuickAssist adapter, which is a low-profile PCIe x8 (Gen 3) card that accelerates crypto operations. Asynchronous hardware acceleration has been added for the following crypto algorithms:

* PKI: RSA public/private (CRT/non-CRT), ECDSA/ECDH, DH
* Cipher: AES CBC/GCM, DES3
* Digest: MD5, SHA, SHA224, SHA256, SHA384, SHA512 and HMAC.

Here are our benchmarks using our asynchronous benchmark application running multiple threads with CPU affinity in user space:

* RSA 2048 public: 209,909 ops/sec
* RSA 2048 private: 41,999 ops/sec
* DH  2048 key gen: 112,491 ops/sec
* DH  2048 key agree: 95,129 ops/sec
* ECDHE 256 agree: 55,117 ops/sec
* ECDSA 256 sign: 46,798 ops/sec
* ECDSA 256 verify: 28,917 ops/sec
* AES-CBC Enc: 2,932 MB/s
* AES-CBC Dec: 2,882 MB/s
* AES-GCM: 2,903 MB/s
* 3DES: 1,511 MB/s
* MD5: 2,309 MB/s
* SHA: 5,068 MB/s
* SHA-224: 2,392 MB/s
* SHA-256: 1,275 MB/s
* SHA-384: 2,020 MB/s
* SHA-512: 1,908 MB/s

Performed on an Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, 12GB RAM, with Intel QuickAssist is DH895xCC.

Additionally we’ve fully implemented asynchronous TLS client/server support in all wolfSSL PKI, Encrypt/Decrypt, Hashing/HMAC and Certificate Sign/Verify.

Please contact us at facts@wolfssl.com if you are interested in evaluating these new features.

Intel ® SGX (Software Guard Extensions) allows for additional security and a smaller surface area for attack. One way this is accomplished is by restricting access to portions of memory even from other applications running on the same computer. This additional security is for both code that is being executed and stagnant information with “sealing” data.

Do you have a use case where cryptography with Intel’s ® SGX is needed?

wolfSSL has a port to use SGX located in the directory wolfssl-root/IDE/WIN-SGX/ and two demo examples of creating an Enclave that links with the wolfSSL embedded TLS/SSL library.
Linux/Unix SGX example: SGX Linux
Windows example: SGX Windows

Interested in using AWS IoT with MQTT?

We added an Amazon Web Services (AWS) IoT example to our wolfMQTT client in our latest wolfMQTT v0.12 released on 12/20/16.

For this example we setup an AWS IoT endpoint and made it available for testing. AWS uses TLS with a client certificate for authentication. The example is located in /examples/aws/.

You can download the latest release from our website or clone on GitHub. For more information please email us at facts@wolfssl.com.
