These are command-line executables. Follow these instructions to decrypt a message (instructions included in distribution). Also included are the current system parameters and default config files. You can run your own IBE system with these.

Source Code

The Stanford IBE system was developed under Debian GNU/Linux. The tarball contains code for the private key generator, a command-line IBE utility (which performs encryption, decryption, key recombination and key requests), a utility for generating system parameters and more.

Configuration is done by editing the Makefile. Several libraries are required for compilation. It has been successfully compiled on Solaris, albeit with minor changes to the code, and also cross-compiled for Windows with a Linux port of mingw. (See this page for some tips on cross-compiling GMP and OpenSSL.)

Fixed bug in request.c (wasn't initializing SSL library).
Released Wed Jul 10 14:03:51 PDT 2002

Required libraries:

The GNU MP library: fast multi-precision arithmetic.
OpenSSL: SSL and cryptographic routines.

Both libraries are part of the Debian GNU/Linux distribution. To install them via apt, type apt-get install libssl-dev libgmp3-dev on the command-line (as root).

Latest changes

0.7.2: Fixed bug in request.c (wasn't initializing SSL library). Wed Jul 10 14:03:51 PDT 2002
0.7.1: The crypto_encrypt and crypto_decrypt family of functions now handle the IV and HMAC themselves: they can be viewed as providing an interface to a blackbox IND-CCA cipher. Some code cleanup. Tue Jul 2 12:03:39 PDT 2002
0.7.0: Improved test suite. Signatures have been tested (there was one bug in IBE_sign() that is now fixed). Removed almost all globals. Can have multithreaded programs with each thread running at least one IBE system simultaneously. Big API changes. Some functions that should've had return codes now have them.
0.6.0: Fixed several memory leaks and a few bugs. Small API changes. Minor modifications to system parameters, encryption format.
0.5.2: some minor fixes due to kromJx
0.5.1: minor API changes, fixed unMACed IV bug, support for multiple recipients, file format changes.
0.5.0: more API changes, new signature functions, removed some hard limits, removed old encrypt/decrypt functions and replaced them with ones that use the KEM functions.
0.4.0: some API changes, hash function bug fixed, major code cleanup, new KEM functions
0.3.2: request.c bugfix, minor code cleanup
0.3.1: Makefile is cleaner and has new options. Many #ifdefs removed. Platform-dependent code in separate files.
0.3.0: new version numbering system, last digit is minor version, to be incremented for bugfixes.
format.c bugfix due to James Mickens. New fp2_set_str() function.
(Compatible with version 0.22.)
