Starting Sep. 5, 2020, Ivy development is moving to https://github.com/kenmcmil/ivy.

IVy is a research tool intended to allow interactive development of protocols and their proofs of correctness and to provide a platform for developing and experimenting with automated proof techniques. In particular, IVy provides interactive visualization of automated proofs, and supports a use model in which the human protocol designer and the automated tool interact to expose errors and prove correctness.

On Debian-based Linux ditributions such as Ubuntu, download and install the file ms-ivy_X.X_YYYY.deb where X.X is the IVy version and YYYY is the machine architecture. Use your system’s package manager to install this package, or the following commands:

$ sudo dpkg -i ms-ivy_X.X_YYYY.deb
$ sudo apt-get install -f

The first command will report missing dependencies, which will be installed by the second command.

The Windows binary distribution is in the form of a zip archive. Download the file ivy.X.Y-.Windows-z86.zip, where X.X is the IVy version (this will work on both 32-bit and 64 bit Intel Windows). Use Windows Explorer to extract this archive in the directory C:\. This should give you a directory C:\ivy. To use IVy in a command window, first execute this command:

> C:\ivy\scripts\activate
