Genode OS Framework
Tool kit for building highly secure special-purpose operating systems
*** Genode migrated to https://github.com/genodelabs/genode *** The Genode OS Framework is a tool kit for building highly secure special-purpose operating systems. It scales from embedded systems with as little as 4 MB of memory to highly dynamic general-purpose workloads. Genode is based on a recursive system structure. Each program runs in a dedicated sandbox and gets granted only those access rights and resources that are needed for its specific purpose. Programs can create and... -

Tranalyzer
Tranalyzer flow generator packet analyzer moved to: tranalyzer.com
The Anteater moves to a new site, available under tranalyzer.com. This tool generates extended netflow-like flow/packet statistics from large pcap files or ethernet interfaces. It is intended to serve as a tool for IT troubleshooting, encrypted traffic mining, AI preprocessing and forensic analysis. A packet based "tshark mode" for detailed header and content inspection is improved for troubleshooting and security purposes. Flow based and packet based content inspection and extraction,... -

Primes
Calculate primes by using extremely fast sorting
This project considers the problem of calculating primes as a sorting problem. It includes the most efficient tree-based sorting algorithm that is possible and shows that finding a new prime can be done by sorting the differences between the previous primes in the right way. Unfortunately it has turned out that going this way is even more slowly than trying to find primes by brute force. So it can only be used as a test with heavy load for the sorting algorithm, which can be used for... -

ext2 info hiding mod
Information Hiding Modification for EXT2
This modification of the ext2 kernel module allows to create files (cover files) whose block arrangement gets manipulated to represent a binary code, which can be extracted later. The information hiding approach used in this project was introduced by Khan et. al in 'Designing a cluster-based covert channel to evade disk investigation and forensics' (1st approach). Algorithm: When a cover file is written, an even blocknr. (for the 1st datablock) is choosen to represent a 0 or an odd... -

AUM CSPRNG & Stream Cipher
A minimal CSPRNG reflecting the Zen of cipher design
AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key. -

The MOTET Cipher & SE Scrambler
A tiny, fast encryption tool in C
MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that... -

MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only... -

BEDBUG CSPRNG & Stream Cipher
A family of FLEA-inspired CSPRNGs and Stream Ciphers
BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a... -
