eIDAS and electronic signatures

Electronic signatures, refer to all methods applicable for signing non-printed documents. There are many approaches to electronic signatures, and not all of them are legally binding in the same way as a hand signature.

In general, the eIDAS regulations distinguish between three types of electronic signatures:

  • Simple electronic signatures (SES)
  • Advanced electronic signatures (AdES)
  • Qualified electronic signatures (QES)

Within the EU, Qualified electronic signatures are the only ones that are given the same legal value as hand-written signatures. Within Norway, Advanced electronic signatures are also given this legal value.

According to Norwegian legislation, Advanced electronic signatures (AdES) are given the same legal value as hand-written signatures

As such, Advanced electronic signatures can be used to digitize processes that traditionally have relied upon hand-written signatures. The applications here are endless, including

  • Forming a customer relationship
  • B2C, C2C and B2B contracts and transactions
  • Signing loan papers
  • Submitting declarations (for use in e.g. insurance, public services)
