    SEPIA: Security-oriented PN Framework

    SEPIA: Security-oriented PN Framework

    Petri net framework for security related modeling and reasoning.

    SEPIA provides implementations for various types of Petri nets. Along Place/Transition-nets, it supports Petri nets with distinguishable token colors and defines coloured workflow nets, where coloured tokens are interpreted as data elements used during process execution. To support information flow analysis of processes, SEPIA defines so-called IF-Nets, tailored for security-oriented workflow modeling which enable users to assign security-levels (HIGH, LOW) to transitions, data elements and...

    WOLFGANG

    WOLFGANG

    Editor for Petri nets

    Wolfgang is a lightweight tool that allows users to easily create and edit Petri nets and check them against general and workflow specific net properties. Specifically, Wolfgang supports full PNML conform editing functionality of Place-Transition Nets (P/T-Nets) and Colored Petri Nets (CPN) as they are defined in the SEPIA package. Its simple and easy to use interface allows to quickly create Petri nets from scratch, edit them graphically in many ways, store and even export them as PDFs. Use...

    xorlisp

    Bit level lambda continuations and nothing else - Queue automata

    Not working yet. To deal with the Halting Problem, computing and data are navigated using debugger ops: linearForward and treeForward, which navigate an astronomically large bit string where 1 is ( and 0 is ). All pairs are derived from (). For example, true is represented as ((()())()), and false is (()(()())). It appears related to the church encoding of lambda where T chooses first parameter and F chooses second, of a pair. Continuations are nearly finished code and are represented as a...

    Immutable Sparse Wave Trees (WaveTree)

    Realtime bigdata tool for bit strings up to 2^63 based on AVL forest

    Realtime bigdata tool at the bit level based on immutable AVL forest which can be run in memory or, in future versions, as a merkle forest like a blockchain. Main object is a sparse bit string (Bits) that efficiently scales up to 2^63 bits normally compressed as forest has duplicated substrings. Bits objects support reading bit, byte, short, int, or long (Java primitives) at any bit index in 64 bit range. Example: instead of building a class to hold a header and then data, represent all of...
