MatrixSSL is an embedded SSL and TLS implementation designed for small footprint devices and applications requiring low overhead per connection. The library is less than 50K on disk with cipher suites. It includes SSL and TLS client and server support, session resumption, and implementations of RSA, AES, 3DES, ARC4, SHA1, and MD5. The source is well documented and contains portability layers for additional operating systems, cipher suites, and cryptography providers.
CyaSSL is a C-language-based SSL library targeted for embedded and RTOS environments, primarily because of its small size and speed. CyaSSL supports the industry standards up to the current TLS 1.2 level, is up to 20 times smaller than OpenSSL, includes SSL client libraries and an SSL server implementation, includes an OpenSSL compatibility layer, and offers several progressive ciphers such as RABBIT and HC-128. Dual licensed under both the GPLv2 and standard commercial licensing, it caters to a wide range of projects.
OpenBeacon is a open and generic design for an active wireless transceiver device hardware that operates in the 2.4GHz ISM band. The tag contains a unique serial number, but may have other information like acceleration measurement. The OpenBeacon tag is designed as a transceiver device, and therefore both transmits and receives radio waves. The intention of this project is to offer a wide range of use cases such as visitor or item tracking and wireless remote control with a free self-contained and low-cost RFID design. It enables wireless remote control application and ultra low power wireless meshing nodes.
