DIGITAL SIGNATURE IN VIETNAM
We have seen a ramp up in the e-commerce and online activities (online meetings, signing e-contracts, signing e-resolutions) in the covid-19 pandemic all over the world and Vietnam is no exception. This blog is to discuss some features of digital signature and authentication of digital signature under Vietnamese law.
1) In general, Vietnamese law recognizes the legal validity of e-contract and e-signature which satisfy the requirements at law. However, in certain cases, as a matter of practice digital signature (as opposed to other types of e-signature in general) may be specifically required since it is secured. Digital signature (chữ ký số) is a type of e-signature which is created by transformation of a data message using an asymmetric cryptosystem whereby the person having the initial data message and public key of the signatory may accurately verify (a) whether such transformation is created with a private key corresponding to the public key in the same key pair, and (b) whether the data message has been altered since the transformation (Article 3.6 of Decree 130 of the Government dated 27 September 2018 guiding the Law on E-transaction on digital signature and digital signature providing services (Decree 130/2018)).
