Anna Lysyanskaya, 31.

The article describes the innovative work of Anna Lysyanskaya, who has been included in the 2007 TR35 list of world's top innovators under the age of 35. She has developed a practical way for people to securely log in to websites without providing any identifying information. Her approach relies on zero-knowledge proofs, which allows one to subscribe using a pseudonym and receive digitally signed credentials. In collaboration with Jan Camenisch of the IBM Zürich Research Laboratory, Lysyanskaya developed algorithms that make both generating and testing credentials much more efficient.
