Abstract
A method of generating a hierarchical deterministic keys portfolio, in particular to sign transactions sent to a blockchain. The generation method includes an initialization phase by an administrator and a phase of setting parameters for at least one user. Private key usage contexts are created from the administrator account, each context specifying conditions for use of the private key in said context. User accounts 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, the usage context to which the user account is attached, and the user's identifier.
