CMX Offers SSL/TLS for Embedded TCP/IP Applications

Widely Deployed TCP/IP Stacks add small footprint SSL/TLS reduce security cost and complexity

Jacksonville, FL - March 5, 2012 - CMX Systems, well-known designer of real-time operating systems, TCP/IP, Flash File Systems and USB software provides the SSL/TLS ( Secure Socket Layer/Transport Layer Security ) Add-On for CMX's widely deployed, CMX-MicroNet and CMX-TCP/IP stacks. The SSL/TLS Add-On option provides SSL/TLS server and client support and a comprehensive suite of security standards for embedded devices such as; crypto and hash functions inlcuding RSA, 3DES, AES, ARC4, SHA1, SHA2, MD2, MD4 and MD5, X.509 certification processing, signing and verification, self-test support for integration, test and compatibility verification.

“For many designers tasked with adding internet or network connectivity to embedded designs, the requirement for secure communications has been a challenge in terms of cost and complexity. With our SSL/TLS option for CMX’s small footprint TCP/IP stacks, designers can now leverage the latest microprocessor technology and implement security for network enabled devices at extremely competitive price points” said Chuck Behrmann, CEO and President at CMX Systems.

CMX SSL/TLS is designed for ease of use and eliminates the need for time-consuming roll-your-own solutions or derived libraries which compromise footprint and memory or rely on ANSI C memory heap often resulting in memory thrashing and fragmentation when used for SSL processing. SSL/TLS eliminates these problems using a self-contained internal memory manager with fine-grained sizing and tuning features to optimize platform memory allocation. Designers can further optimize flash and RAM by enabling only those features required for the specific application.

CMX-MicroNet is a TCP/IP stack specially crafted to work with virtually all processors and features an extremely small Flash requirement and minimal RAM requirements of about 500 bytes plus buffers for packets. The base CMX-MicroNet software package includes UDP, TCP, IP, Modem, SLIP, ICMP Echo, IGMP, and Virtual File system. Add-On Options available are: SSL/TLS, HTTP Web Server, DNS Client, FTP, SMTP, SNMP, DHCP Client, TFTP Client, SNTP, Fragmentation, POP3, PPP, CHAP, Telnet, Ethernet (ARP, BOOTP) and Wireless.

CMX-TCP/IP is a full-featured, 100% RFC compliant, TCP/IP stack targeted at 16- and 32-bit processors and provides virtually all of the protocols, link layers, interfaces, and device drivers required for most networking applications. The basic CMX-TCP/IP stack provides: UDP, TCP, IP, ICMP, IGMP, DNS, ARP, SLIP, Ethernet, an RTOS porting layer, a Standard BSD socket interface and a High Performance Socket Interface. Add on options include: DHCP, IMAP4, FTP, NAT, POP3, PPP, PPPoE, SMTP, SNMP, Telnet Server, TFTP/BOOTP, Web Server, SSL/TLS and Wireless.

CMX TCP/IP stacks, USB stacks and file systems can operate with or without an RTOS. All CMX products feature full source code, no royalties, free technical support and updates with every purchase.

About CMX Systems, Inc.:

Since its inception in 1990, CMX Systems has focused on providing its customers with all of the tools needed to program their embedded applications. The company’s core business is to develop and support real-time, multi-tasking operating systems (RTOS), TCP/IP stacks, Flash File Systems, USB stacks and the CANopen stack for a wide variety of 8-bit, 16-bit, and 32-bit microcomputers, microprocessors, and digital signal processors. The company’s RTOSes support more than 50 processor families and over 30 C-compiler vendors. CMX also offers the tiny CMX-MicroNet, which is a unique TCP/IP stack that is targeted for 8-, 16-, 32-bit and DSP processors with limited ROM and/or RAM and CMX-TCP/IP, a full-featured TCP/IP stack designed for 16-, 32-bit and DSP processors. CMX additionally offers five different Flash File Systems to best meet the memory management needs of embedded developers. CMX-USB™ is offered for designers wishing to add USB connectivity to their products. For more information, please visit CMX Systems’ website at
