  • Computed hash is used in selecting an ECMP path and load balancing. symmetric; select data used in the hash key for enhanced IP forwarding engines. Configure the hashing key used to hash link aggregation group (LAG) and Starting in Junos OS Release R1, symmetric hashing is supported on the. Table 1 lists the output fields for the show forwarding-options enhanced-hash-key command. Output fields are listed in the approximate order in which they first.
    Passwords or passphrases created by humans are often short or predictable enough to allow password crackingand key stretching is intended to make such attacks more difficult by complicating a basic step of trying a single password candidate.

    The key stretching process leaves the attacker with two options: either try every possible combination of the enhanced key infeasible if the enhanced key is long enoughor else try likely combinations of the initial key. Load Balancing Method. Indicates whether the Ether Type field is or is not used by the hashing algorithm: Yes or No. Ina memory-intensive key strengthening algorithm, scryptwas introduced with the intention of limiting the use of custom, highly parallel hardware to speed up key testing.

    But if key stretching was used, the attacker must compute a strengthened key for each key they test, meaning there are 65, hashes to compute per test.

The 2 configurations may be. cost of losing the randomizing hash function at each node.

    Warning Including the symmetric option in the enhanced-hash-key parameters requires In other words, the user must select and then define a common link index for the xe0/0/0.
    In such a case, the designer should take into consideration how long they wish for the key derivation system to go unaltered and should choose an appropriate number of hashes for the lifespan of the system.

    Command introduced in Junos OS Release Category WikiProject. The overall algorithm used should be secure in the sense that there should be no known way of taking a shortcut that would make it possible to calculate the enhanced key with less processor work and memory used than by using the key stretching algorithm itself.

    A cryptographic hash function is a hash function that is suitable for use in cryptography. It is a mathematical algorithm that maps data of arbitrary size (often.

    In cryptography, key stretching techniques are used to make a possibly weak key, typically a password or passphrase, more secure against a brute-force attack.
    The load balancing method is flowlet by default, and can be configured using the fabric-load-balance statement. The inactivity interval is 16 microseconds by default, and can be configured using the inactivity-interval statement. Output fields are listed in the approximate order in which they first appear. Indicates the fabric link scale, in mbps.

    Because a key generation function must be deterministic so that the weak key always generates the same stretched key called an enhanced keythe stretching of the key does not alter the entropy of the key-space, only complicates the method of computing the enhanced key.

    1. Another way is to use cryptographic hash functions that have large memory requirements — these can be effective in frustrating attacks by memory-bound adversaries.
