Automated Discovery of New $L$-Function Relations Open
$L$-functions typically encode interesting information about mathematical objects. This paper reports 29 identities between such functions that hitherto never appeared in the literature. Of these we have a complete proof for 9; all others …

RISC-V: #AlphanumericShellcoding Open
We explain how to design RISC-V shellcodes capable of running arbitrary code, whose ASCII binary representation use only letters a-zA-Z, digits 0-9, and either of the three characters: #, /, '.

CheriRTOS: A Capability Model for Embedded Devices Open
Embedded systems are deployed ubiquitously among various sectors including automotive, medical, robotics and avionics. As these devices become increasingly connected, the attack surface also increases tremendously; new mechanisms must be d…

ARMv8 Shellcodes from 'A' to 'Z' Open
We describe a methodology to automatically turn arbitrary ARMv8 programs into alphanumeric executable polymorphic shellcodes. Shellcodes generated in this way can evade detection and bypass filters, broadening the attack surface of ARM-pow…
