emSecure

emSecure is a digital signature suite for embedded systems to protect vital products and assets, offering 100% protection against hacking. Based on asymmetric encryption algorithms with two keys, SEGGER's digital signature suite ensures protection against hacking: signatures cannot be forged by the reverse engineering of the firmware. What's more: emSecure can make it impossible to create a clone of an embedded device by simply copying hardware and firmware. And it can do much more, such as securing firmware updates distributed to embedded devices and authenticating licenses, serial numbers, and sensitive data.

emSecure is a very complete package, including ready-to-run tools and functionality for generation of keys and signatures for your embedded solution. The emSecure source code has been created from scratch for embedded systems, to achieve highest portability with a small memory footprint and high performance. It is not covered by an open-source or required-attribution license. It can be integrated in any commercial or proprietary product without the obligation to disclose the combined source. It can be used royalty-free, taking less than one day to add and integrate emSecure into an existing product.

Key features

  • Asymmetric algorithms: Dual keys (private & public) ensure 100% security
  • Hardware-independent: Works on any CPU with no extra hardware needed
  • Applicable for new & existing products
  • Complete package: Key generator & tools included
  • Full source code available
  • Protection of personal files with the free Sign & Verify tool

Security algorithms

emSecure allows signing data with the RSA asymmetric cryptography algorithm. Data is signed by sending the data's hash to the server. A signature is generated and returned to the requester. Anyone can then use the public key to verify that the data was signed by someone having access to the matching private key.

Based on the industry-standard signature scheme RSA-PSS, the default configuration uses 2048bit RSA keys and SHA1 for signing. However, for PSS, a whole set of modern digest algorithms are available, and RSA keys between 1024 and 8192 bits are supported, with keys of at least 2048 bits recommended.

Simple & powerful API

emSecure has a simple yet powerful API. It can be easily integrated into an existing application within a day. emSecure incorporates proven security algorithms as proposed by NIST. The algorithms are proven to be cryptographically strong and can provide maximum security to your applications.

High performance

emSecure has been created from scratch to achieve highest portability and performance, with a very small memory footprint. Product developers can therefore profit from the security of digital signatures in embedded applications. Even on small, single-chip microcontrollers, there is no need for additional hardware such as external security devices or external memory.

Sign&Verify — The drag-and-drop application

The Sign & Verify application enables easy drag-and-drop creation of emSecure digital signatures and verification of signed files. It may be used freely for personal use too, for example make sure files stored on a server are not changed or to allow communication partners to send/receive files knowing nothing has been changed during transmission.
