The Covert Channel Educational Analysis Protocol (CCEAP) is a simple network protocol designed for teaching covert channels (network steganography) to professionals and students. It is also an easy-to-use covert channel traffic generator.

Changelog (changes were already made in 2019):
v. 0.6.2 : 2021-04-26

• improved welcome message
• added -q for the client, too.

CCEAP v.0.6.1 released!

After almost a year and several tiny changes, also in celebration of Easter :), it is time for a new sub-version. This is what has changed since v. 0.6.0:

v. 0.6.1 : 2019-04-21 (Easter)

• new parameter -T for provision of a default IAT value used for all packets
• better error handling and error reporting
• add random sequence number tool rand_seq for use with -s
• do not send more packets than allowed by -c when packets are duplicated; thanks to J. Kammerlander for reporting this issue
• increased maximum number of packets that can be sent
• make the tool compile under Debian (use -lrt)
• added runserloop target in Makefile to run the server in a loop

CCEAP v.0.6.0 released!

The new version 0.6.0 contains some slight improvements:

• slightly improved client (help) output thanks to student feedback
• fixed an error message in the client
• increased number of packets that can be sent from 255 to 2048
• add iat_encode tool to help encode messages as IAT values
• allow the combination of -c with -s; loop sequence numbers if necessary and output all sequence numbers when -v is used

CCEAP v.0.5.2 released!

This is a new minor release containing the following changes:

• added code to compile CCEAP under MacOS (not officially supported)
• performed additional small improvements within the documentation
• fix header dependency in Makefile for C object files

CCEAP v.0.5.1 released!

In comparison to version 0.5.0, this minor update comes with a '-q' parameter that keeps the server a bit more quite when running in a loop. In addition, the documentation was improved and sample exercises (including solutions) were added.
