Selected Work Experience

Kryptologik Inc. /Mission Viejo, CA.

01/2017 – 04/2018: Senior Systems Architect.

• KLOCK/FPE: Hardware & software based solution addressing database security (data protection, access control and monitoring). This product protects personally identifiable information (PII) as well as other sensitive data while maintaining database query capabilities. o KLOCK handles crypto operations and safeguards protection keys. o Advanced authentication schemes: PKI-based (EC-P256), OTP (one-time password), shared-secret (SHA256-HMAC).

o Usage control and monitoring.

o Support for X509 certification.

• KLOCK/U2F: USB HID token used as Universal 2nd Factor authentication. This token supports FIDO specification and is supported by big companies such as Google, Facebook, Github, ...

• SPP: Smart Programming Platform: Consists of hardware and software components that are targeted for software and firmware security for IOT and other similar devices. o Secure delivery of software to untrusted contract manufacturing. o Comprehensive target validation and production quality. o Customization: identification, serialization, key generation ... o Licensing and control of production quantity.

o Secure remote control, update and monitoring.

• FOLDING: Invented a new algorithm called FOLDING to speed up Elliptic Curve scalar multiplication. FOLDING improves ECC performance by a factor of 4, 8 or more. I have implemented this technique in https://github.com/msotoodeh/curve25519 project which achieves new speed record.

• Whitebox-AES/ARIA: Invented a new white-box system that can be used to implement highly secure cryptographic algorithms such that keys and intermediate state information do not show up in clear during the execution of the code. For additional info, visit https://github.com/msotoodeh/WhiteBoxCrypto and click the AES demo link.

• Whitebox-FDE: Invented a new FDE (Formatted Data Encryption) algorithm that is whitebox- friendly. Whitebox-FDE is used for encryption of formatted data such as social security and credit card numbers in untrusted environments such as point of sale systems. For additional information visit https://github.com/msotoodeh/WhiteBoxCrypto/tree/master/FDE Magtek Inc. / Seal Beach, CA.

05/2017 – 08/2017: Senior Systems Consultant.

• oDynamo: PCI DSS compliant card reader/terminal for point of sales systems. This system is based on Maxim-Jibe ARM processor utilizing embedded Linux and u-boot. o Security review for compliance with PCI in terms of data and side-channel security. o Added support for 4-bit ECC NAND flash memories for both u-boot as well as Linux kernel. This support was based on using Micron’s NAND flash chip supporting 1-bit ECC for the 1st 128KB block and 4-bit ECC for the rest of the memory. o Adding GDB stub to be able to debug the code when JTAG port is not an option. o Improved code signing design for extendibility and better key management. mehdi sotoodeh

Numecent Inc. / Irvine, CA.

01/2014 – 12/2016 Senior Systems Architect.

• AppWall Publisher: Creating virtualized documents and their associated readers utilizing cloudpaging technology.

o Design and development of a windows printer system that creates virtualized App-set packages.

o Development of SOAP-based web interfaces to push the generated packages to the servers and handle license generation.

• Security review and propose improvements for client, server and packager components.

• Development and implementation of new set of crypto routines and libraries for kernel mode drivers as well as user mode player.

• Design and development of several system components (V2 token, trusted time, server restriction access, license management

• Intel SGX: Worked with Intel development team on SGX (Software Guard eXtension). o Design and development of a virtual HSM and integration with cloudpaging player. o Created a server to handle remote attestation and secure delivery of payloads (C#, C++, JSON, and WinHTTP).

o Provided feedback on SGX security issues and improvements. o Discovered and reported a vulnerability in SGX crypto and the way key derivation was designed. Intel fixed this issue with SGXSDK 1.6.

SafeNet Inc. Irvine/Redwood City, CA

03/2001-07/2013. Senior Systems Architect / Member of CTO office.

• DUAL-VIEW: Invented a new concept using hypervisor and EPT (Extended Page Table) in order to provide dual view memory pages for the virtual machines. With this system, two different physical pages are mapped into a virtual address based on who is accessing this virtual address. One view is accessible to trusted callers and another view is visible to untrusted callers. This effectively provides exclusive execution environment which runs in the context of the guest VM while is it fully protected from un-trusted pages of the system (POC based on XEN hypervisor).

• KeySecure/DataSecure and Protect-V: Part of the design and development team (Embedded- Linux, C, C++, and Assembly).

• Compact Java VM: Design and development of a VM and tools that allow conversion of standard Java classes into a compact and proprietary byte code. This virtual machine was implemented on SHK consuming only 24KB code space. Dedicated tools enable developers to move part of their applications to a secure VM inside SHK tokens. Conversion tool generates mehdi sotoodeh
