CARTS: Contextual Autoregressive Rank Transcoding Steganography for Full-Capacity Keyed Text Encoding
Wissam Ghantous, Alexander V. Mantzaris
Autoregressive language models can be used to transform a payload text into a stegotext of identical token length by preserving per-position rank information across contexts - a me…
On a Roll Again: Analysis of a Dice Removal Game
Francesco Camellini, Wissam Ghantous, Andrea M. Lanocita +4
Suppose we have dice, each with faces (assume ). On the first turn, roll all of them, and remove from play those that rolled an . Roll all of the remaining dice…
Cycles and Cuts in Supersingular L-Isogeny Graphs
Sarah Arpin, Ross Bowden, James Clements +3
Supersingular elliptic curve isogeny graphs underlie isogeny-based cryptography. For isogenies of a single prime degree , their structure has been investigated graph-theoreti…
A symmetric -adic symbol for triples of modular forms
Wissam Ghantous
In 2014, Darmon and Rotger defined the Garrett-Rankin triple product -adic - function and related it to the image of certain diagonal cycles under the -adic Abel- Jacobi m…
Loops, Multi-Edges and Collisions in Supersingular Isogeny Graphs
Wissam Ghantous
Supersingular isogeny graphs are known to have very few loops and multi-edges. We formalize this idea by studying and finding bounds for the number of loops and multi-edges in such…
