What is forward protection?
Forward secrecy protects past sessions against future compromises of keys or passwords. By generating a unique session key for every session a user initiates, the compromise of a single session key will not affect any data other than that exchanged in the specific session protected by that particular key.
What’s a cat5 world?
➢ Category V missions comprise all Earth-return missions. The concern for these missions is the protection of the terrestrial system, the Earth and the Moon. ➢ For solar system bodies deemed by scientific opinion to have no indigenous life forms, a subcategory “unrestricted Earth return” is defined.
What is a cat 2 planet?

| III | Mars | Completed |
How is the Mars rover sterilized?
Third, engineers and technicians sterilize the spacecraft, in part by manually cleaning with polyester wipes doused with 70 percent isopropyl alcohol.
How does forward secrecy work?
Perfect forward secrecy means that a piece of an encryption system automatically and frequently changes the keys it uses to encrypt and decrypt information, such that if the latest key is compromised, it exposes only a small portion of the user’s sensitive data.
How are spacecraft sterilized?
On spacecraft, there are only two accepted methods so far: dry heat (cooking the surface at 233 degrees Fahrenheit, or 111.7 degrees Celsius, for 30 hours) or using hydrogen peroxide.
Is Cat7 shielded?
Cat7 and Cat8 cable are fully shielded, and referred to as S/FTP. What this means is that not only does it have an overall braided shield, but also each individual pair is foil shielded as well.
What does the M in M class planet stand for?
In the Star Trek fictional universe, habitable Earth-like planets are designated as Class M planets, where M stands for the Vulcan word Minshara. In the real universe such planets would also be known as class M, but for different reasons. If Mars were at the orbit of Earth, it would still be cold and hostile.
How can we prevent contamination on Mars?
The primary strategy for preventing contamination of Mars with Earth organisms is to be sure that the hardware intended to reach the planet is clean.
Why do we use PFS?
Perfect Forward Secrecy (PFS), also called forward secrecy (FS), refers to an encryption system that changes the keys used to encrypt and decrypt information frequently and automatically. This ongoing process ensures that even if the most recent key is hacked, a minimal amount of sensitive data is exposed.
