wolfSSL is always adding new ports to our highly portable wolfCrypt library! We’re continuing our series on the latest open source project ports—this week, we’re featuring tcpdump.

We have integrated wolfSSL with tcpdump, a powerful command-line packet analyzer. This update allows for the use of tcpdump with our FIPS-validated crypto library, wolfCrypt. Tcpdump is a versatile tool with many options and filters, and is commonly used to capture or filter TCP/IP packets that are received or transferred over a network on a specific interface. Its long-running history ensures that there are many resources available for learning how to use this tool (See the tcpdump Wikipedia page for more info). 

Through the OpenSSL compatibility layer, tcpdump is able to call into wolfSSL. Visit the GitHub page here: https://github.com/wolfSSL/osp/tree/master/tcpdump/4.9.3

News to look forward to—wolfSSL plans to integrate wolfTPM, our portable TPM 2.0 library, into U-Boot! This would extend the TPM 2.0 capabilities in U-Boot to include signature verification and measured boot.

For many platforms, we can replace U-Boot such as on the Xilinx UltraScale+ MPSoC.

wolfBoot is a portable secure bootloader solution that offers firmware authentication and firmware update mechanisms. Thanks to its minimalistic design, wolfBoot is completely independent from any OS or bare-metal application. Some of its key features include:

• Partition signature verification using ED25519, RSA and ECC
• Encryption of partitions
• Updating of partitions in the boot loader
• Measured boot with TPM 2.0 PCR registers
• Offloading to crypto coprocessors like the TPM 2.0 modules
• Version checking for updates
• Rollback on failed updates

Public key infrastructure or PKI is important term used to define everything that is used to “create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption.” (https://en.wikipedia.org/wiki/Public_key_infrastructure) As RSA and ECC are one of the main algorithms used for PKI key generation, we are wondering if anyone is interested in RSA 3k or ECC 384 support in wolfBoot?

wolfSSL has long been aware of the quantum threat to modern cryptography. Though quantum computing currently exists on small scales, research has determined enough to know that once full-scale quantum computing is available, all modern cryptography (RSA, ECC, etc.) will no longer be secure. Furthermore, the proven usage model of Quantum Computing as a Service (QCaaS) via the Cloud means that quantum capabilities will be more widely available, posing a greater security threat. This risk is why wolfSSL provides support for integration with the NTRU cryptosystem and an implementation of the QSH TLS extension. 

With NIST already having announced the Round 3 finalists of the Post-Quantum Cryptography Competition, we thought it was time to update our quantum-safe offerings. WolfSSL will soon support integration with the Open Quantum-Safe project’s libOQS. Initial support will be for Key Exchange only using all parameter sets of Crystals-Kyber, NTRU, and SABER for TLS 1.3. With perfect forward secrecy, these algorithms can protect you from the “Harvest and Decrypt” threat model.

“Harvest and Decrypt”

If encrypted sensitive data is stolen (harvested) today, it will be accessible (decrypted) once a sufficiently-powered quantum computer is available. If the sensitive information has a secrecy requirement that extends beyond the time it will take to develop large-scale quantum computing, then that data should be considered at risk today. The quantum threat to current confidential data demonstrates the importance of migrating to quantum-safe solutions as soon as possible. For more details, you can look up “Mosca’s Inequality”.

Next Steps

To continue future-proofing encrypted data streams, wolfSSL plans to hybridize key construction algorithms with NIST-standardized ECDSA components. These hybridized algorithms will continue to be FIPS compliant under the current NIST standards. In addition, wolfSSL is developing a test for post-quantum cURL, coming in the next 4 to 6 weeks.

wolfSSL is attending ICMC (International Cryptographic Module Conference) this week, where we will be talking more about post-quantum computing—come visit us there!
