Abstract
A method for checking a validity of a certificate (600) containing a key associated to a network device (601) in a network, comprises receiving at the network an encrypted content (611) and a validity index (630) associated to the content. The validity of the certificate is evaluated from a time index (606) contained within the certificate, the time index having a value corresponding to a time of issue of the certificate, and from the validity index associated to the encrypted content.
