Welcome to the resource topic for 2013/135

Title:
An MQ/Code Cryptosystem Proposal

Authors: Leonard J. Schulman

Abstract:

We describe a new trap-door (and PKC) proposal. The proposal is ``multivariate quadratic’’ (relies on the hardness of solving systems of quadratic equations); it is also code-based, and uses the code-scrambling technique of McEliece (1978). However, in the new proposal, the error-correcting code is not revealed in the public key, which protects against the leading attacks on McEliece’s method.
