# One Time Use Laptop Ceremony
#### Threat Model
## Threat Model
One time use laptops are specially prepared for using in field operation but can also be used inside of a secure facility. The primary objective of this setup is that the laptop is provisioned ahead of time, and is considered to be secure for use, but is to be destroyed afterwards.
- [ ] isn't the only difference between this and portable multi use that the laptop is resealed?
This flow is the same as [portable reusable laptop ceremony](portable-reusable-laptop-ceremony.md) except instead of tamper proofing the hardware at the end of the ceremony, it is destroyed.

# Portable Reusable Laptop Ceremony
This type of device is essentially just a "One Time Use" device, with the added caveat that the operator has a tamper proofing method available to protect the device between uses. The device can not be trusted by other individuals, but only by the individual who used the device, as there are no other witnesses.
This type of device setup offers reduced security compared to using a a [fixed location](fixed-location-reusable-laptop-ceremony.md) setup, as this type of setup offers additional controls which mitigate attacks.

### Adequate Filler
To achieve the best level of randomness and difficulty of reproducing the arrangement of filler in a vacuum sealed bag, a variety of beads of different sizes and color should be used. They may be made of different materials as well.
To achieve the best level of randomness and difficulty of reproducing the arrangement of filler in a vacuum sealed bag, a variety of beads of different sizes and color should be used. They may be made of different materials as well but plastic is excellent because it doesn't change form when vacuum sealed - which can make it easier to reproduce patterns. Materials such as confetti and packing beans may be used, but because they can be flattened and retain the shape, arranging them in a given pattern is much easier. Other options like beans or lentils have less variety in color and shapes which makes it harder to detect differences.
Examples of filler:
