GENERATION OF A MULTI-USER CONTEXTUAL WALLET OF PRIVATE KEYS AND USE OF SUCH A WALLET

摘要

The present invention relates to a method for generating a deterministic hierarchical key portfolio, in particular to sign transactions intended for a blockchain. The generation method includes an initialization phase by an administrator as well as a configuration phase for at least one user. From the administrator account are created (430) contexts of use of private key, each context specifying the conditions of use of the private key in said context. User accounts (440) are also created, each user account being associated with a private key in the tree structure, the private key of said user being obtained from a master private key of the administrator, from the context of use to which the user account is attached, and the user ID.
