I'm an engineer by formation, with experience in applied cryptography, in particular in Smart Card systems. My current professional work is in contactless payment of public transport.

I currently write a lot as "fgrieu" at https://crypto.stackexchange.com

I'm the author of A072276, A132447..A132454

I once wrote a paper on cryptanalysis of an RSA signature standard, and co-authored a related one https://doi.org/10.1007/3-540-45539-6_5 https://doi.org/10.1007/s00145-007-9007-5
