Abstract: An administration machine for a digital escrow server stores integer values each corresponding to a machine of a group of administration machines. An initialization function calls a polynomial function, unique to the administration machine, of a degree less than or equal to the number of administration machines, with each integer value, in order to obtain first secret values. The function constructs a message including, for each administration machine, the first secret value corresponding to the integer value of said machine. In response to a message having, for each administration machine, a second secret value obtained on calling the polynomial function of said machine on the integer value of the administration machine, the function constructs a resulting secret value from the first and second secret values. An overlay function processes a digital escrow using the resulting secret value unique to the administration machine and resulting secret values unique to similar administration machines.
