The protocol of Fujioka - Okamoto - Ohta secret electronic voting from the standpoint of practical realisation is considered. Formalisation of the protocol is presented as mathematical model and sequence diagramm in UML notation. Recommendations are given at option of separate elements of practical realisation of information system. The criteria of choice of algorithms of symmetric and asymmetric encryption in the protocol are presented. The boundaries of practicality of algorithm of “blind” signature on the basis of RSA crypto-system are considered. Practically useful and relevant to the information system examples of unique identifiers of the users and criteria for their choice are given. Variants of choice of the structure of bulletin and their evaluation on the criteria of convenience and safety of use are offered. The evaluation of practical realisation of information system from the standpoint of information safety are given. Different attack vectors are examined including attack to bulletin, «blind» signature, hash-function and transmission channel.
