Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.

Abstract (eng): Medium sized and large companies often have hundreds of bank accounts.
They may perform great number of transaction to and from these accounts on a daily basis as a part of their banking activities.

File transfer services offer a meaningful way to deliver a large amount of payment instructions and other financial commissions to the bank in a file format.
File transfer system consist of components and subsystems that together receive incoming files, perform authentication, integrity checks, decryption and possibly other tasks on the files before the files are forwarded to payment applications in the bank's production environment.

Nordea Bank has gone through many mergers and acquisitions in the past.
This has resulted in large variety and complexity in technologies and platforms on which the file transfer services are run.
Furthermore there is a growing need for integration and consolidation of systems and services.
This thesis makes a survey to the versatile set of file transfer services, which the Nordea Bank offers today to its corporate customers.
We concentrate on describing the technical architectures of these systems and the major differences and similarities between the many solutions.

The study conducted in this thesis shows that although the file transfer services and their technical implementations vary largely, some common denominators, such as use of symmetric cryptography, exist.

We also surveyed future development trends.
XML and Web Services technologies could be utilized to automate for example management of cryptographic keys and to help standardize the diverse customers' computer environments.
Abstract (fin): Pankin suurikokoisilla yritysasiakkailla on usein satoja pankkitilejä ja monimutkaisia konsernitilirakenteita.
Nämä asiakkaat saattavat tehdä satoja maksuja, tilisiirtoja ja muita toimeksiantoja päivittäin.

Eräsiirtopalvelut tarjoavat mahdollisuuden lähettää pankkiin useita toimeksiantoja kerrallaan tiedostomuodossa.
Eräsiirtojärjestelmä koostuu niistä osista ja alijärjestelmistä, jotka yhdessä vastaanottavat asiakkaan tiedostot ja suorittavat niille tarpeelliset tarkistukset ennen kuin tiedostot siirtyvät edelleen ajatettaviksi maksuliikesovelluksissa.

Nordea Pankki on läpikäynyt historiansa aikana useita fuusioita ja yritysostoja.
Tästä johtuen pankin eräsiirtojärjestelmät ovat monimutkaisia ja suuria.
Tämä diplomityö keskittyy olemassa olevia eräsiirtojärjestelmiin tietoliikenteen näkökulmasta ja löytämään järjestelmien väliltä merkittävimpiä samankaltaisuuksia ja eroja.

Tehty tutkimus osoittaa, että vaikka nykyiset eräsiirtojärjestelmät ovat hyvin kirjavia, niiden väliltä voidaan löytää tiettyjä yhtäläisyyksiä.
Esimerkkinä mainittakoon symmetristen salaustekniikoiden käyttö asiakkaan tunnistamisessa ja tiedostojen eheyden varmistamisessa.

Työssä tutkittiin myös tulevaisuuden kehityssuuntauksia.
XML teknologioita voitaisiin hyödyntää tarvittavan avaintenhallinnan automatisoinnissa ja asiakkaiden tietokoneympäristöjen yhdenmukaistamisessa.
