My new homepage is at http://www.cs.ut.ee/~lipmaa. Please do not bookmark this page, but rather the one at www.cs.ut.ee. The current place here will only contain information about my business activities.
First of all, I have written world fastest implementations of several leading block ciphers, including the new AES (Rijndael), but also IDEA, Twofish, RC6 and MARS. All implementations are available commercially. Please see here for details.
I do consultancy in time-stamping and related areas. My official homepage has information about my background in this area.
My contact addresses are also available from http://www.cs.ut.ee/~lipmaa.
