57AbstractABA method for generating a digital identity (cryptID) of a user (U) for user authentication in electronic transactions, the user (U) being in possession of a cryptographic key pair (συ, πυ) comprising a public key (πυ) and a private key (συ), the method comprising the following steps: computing a hash function of the public key (πυ) thus generating a public key hash value (h( πυ)); digitally signing the public key hash value (h( πυ)) with the private key (συ) thus generating a signed hash value (συ(h(πυ)); establishing the digital user identity (cryptID) to be the pair consisting of the public key (πυ) and the signed hash value (συ(h(πυ)). The digital identity (cryptID) of a user (U) for user authentication in electronic transactions is comprised of the public key (πυ) of the user (U) and a public key hash value (h(πυ)) digitally signed (συ(h(πυ)) with the private key (συ) of the user (U). An electronic transaction document (T) between a user (U) and a recipient (V) is comprised of a transaction content (d) from the user (U) to the recipient (V) and a transaction content hash value (h(d)) signed with the private key (συ) of the user (U).
