Research in applied cryptography and algorithms.
Independent research into cryptographic protocols and implementations under real-world constraints.
RESEARCH
Where cryptography meets implementation.
We study the questions that arise when cryptographic designs meet constrained devices, secure hardware and operational environments.
Algorithms & Primitives
Cryptographic constructions, elliptic-curve methods and post-quantum approaches.
Protocols Under Constraints
Authentication, secure messaging and verification where memory, latency, bandwidth or interoperability matter.
Cryptographic Transition
Algorithm migration, key replacement and backward compatibility in established infrastructures.
Keys & Secure Hardware
Key generation, custody and use across secure elements and hardware-backed environments.
Independent by design.
Independent research and collaboration around specific questions in applied cryptography.
RESEARCH
Key management beyond the algorithm
Why the security of infrastructures depends on more than cryptographic primitives: diversification, provisioning, isolation and lifecycle. Read notes →
IN PRACTICE
Selected work in context.
IN FOCUS
Mobility
Work on cryptographic transition, key architecture and secure access modules in metropolitan ticketing environments.

A COSE_Sign1 object is not its signing input.
Four transmitted fields become a different CBOR structure before signature verification.
Verification is not authorization.
A valid signature answers a narrower question than most applications need to decide.
127 bytes.
An IEEE 802.15.4 calculation begins with 127 octets. After framing and link security, only 81 may remain.
