# How does MISPbump work?
First of all: MISP admins login by providing the base URL of their instance and their authkey (automationkey).
On a successfull login the users profile and the linked organisation information will be downloaded automatically.
On a successfull login the admins profile and the linked organisation information will be downloaded automatically.
This information can be updated at any time from the profile view.
From the main screen you can start a synchronisation process by pressing the dedicated button.
The synchronisation process consists of 3 steps:
1. Key Exchange (unencrypted QR code)
1. Synchronisation Information Exchange (with shared secret encrypted QR code)
1. Upload information to own MISP instance
1. **Key Exchange**
To provide a secure chanel for data exchange, the first step is to generate a shared secret with [Diffie–Hellman key exchange](https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange) ([Elliptic Curve](https://en.wikipedia.org/wiki/Elliptic-curve_Diffie%E2%80%93Hellman)).
#### 1. Key Exchange
[Diffie–Hellman key exchange](https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange) ([Elliptic Curve](https://en.wikipedia.org/wiki/Elliptic-curve_Diffie%E2%80%93Hellman)), where the public part is exchanged via a QR code.
The result is a shared secret which will be used to encrypt the information passed via QR code in step 2.
Public keys are exchanged via QR code.
#### 2. Synchronisation Information Exchange
Local information like Organisation name, UUID, description and User information is encrypted with a from step 1 derived key.
The information can now be securely exchanged via QR code.
1. **Synchronisation Information Exchange**
Contains the following information:
+ Own Organisation: Name, UUID, description, nationality, sector, type and contacts
+ Own User: Email
+ Own MISP instance: base URL
+ Generated: sync user authkey, sync user password
(your partner will create a sync user with these credentials)
#### 3. Upload information to MISP instance
The Synchronisation information is encrypted with AES using the shared secret (from step 1).
The sync process information will be saved securely on the device, that means the upload can be started any time in the future.
1. **Upload information to own MISP instance**
Uploading the information to the MISP instance is accomplished with MISP's REST API.
Uploading consists of the following steps:
