Algebraic Structure Defectoscopy

Welcome to the Algebraic Structure Defectoscopy Laboratory of VEST Corporation S.A.R.L., where block ciphers can be compared against stream ciphers, asymmetric ciphers and hash functions in their quality determined by the security of each individual component as well as their combination.

Although it is impossible to measure the real security of a given cryptographic primitive with a limited set of tests, our results provide a good measure of its potential security demonstrating possible presence of hidden flaws clearly showing whether its security is overestimated or underestimated. Hence the name ‘defectoscopy’, meaning [non-destructive] in-depth analysis uncovering hidden structural flaws or defects.

In this project we aim to collect all the existing block ciphers, stream ciphers, asymmetric ciphers and hash functions under one roof, proving Shannon's 1949 definition of cipher security to be correct. We also want to show that cryptanalytic progress of the past few decades has enabled automated detection of flaws in cryptographic primitives, thus significantly reducing the amount of time required to determine security or insecurity of a given cryptographic primitive.

Note: Please expect significant changes to the content of this web site in the future as we keep it up to date with the ongoing cryptographic research. Our improved tests may increase the number of rounds distinguishable from random for some ciphers in the future.
