SIETSE RINGERS

Cryptography: Idemix, BBS+, zero-knowledge proofs, TLS, signature schemes such as ECDSA, (a)symmetric encryption, AES, HMACs... As an independent solution architect and software engineer, I specialize in digital identity: software implementing privacy-preserving cryptography and authentication technologies. During and after obtaining my PhD in 2016 I have specialized in cryptographic protocols and algorithms focusing on authentication, enabling me to design and implement secure software solutions with a strong focus on privacy-perserving technologies...
