Trust Management

Connected objects identity management

Metatime

Organisations moving to paperless exchanges, whether for internal communications or for relationships with partners or customers, may be required to demonstrate that certain transactions or actions occurred before a given date and time.

The use of a time-stamp token which includes a trusted date and time associated with the document provides an element of proof. Atos, a European actor in IS security, provides metatime, a service to create time-stamp tokens.

Administration

Metatime allows the parameters of timestamping policies to be defined. Each timestamping policy is supported by one timestamping unit.

Flexibility

From electronic transactions to archiving, time-stamp tokens may be used in various contexts.

Expertise

Atos has built up a unique body of expertise in information systems security, bringing together consulting and systems integration expertise and an in-depth understanding of corporate security technologies.

Norms and standards

►  IETF RFC 3161
►  ETSI TS 101 861 (a profile of RFC 3161)
►  X.509 v3 or RFC 5280 for TSU certificates
►  PKCS#11 for the interface with the HSM

►  HTTP or HTTPS for the delivery of time-stamp tokens
►  HTTPS for administration

The success of electronic transactions and of electronic archiving is built upon a fundamental property: the ability to demonstrate before which time transactions took place or documents were archived.

This may be achieved through the use of a time-stamp token that is a signed piece of data including:
a date and time (UTC time)
a hash value computed using a hash function (e.g. SHA 1 or SHA 256)
the identifier of the time-stamping unit (TSU) which produced the time-stamp token.
