A major security flaw was revealed in December 2011 that affects wireless routers with the WPS PIN feature, which most recent models have enabled by default. The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key (PSK). [3]
Most devices also allow the user to enter the key as 5 ASCII characters (0–9, a–z, A–Z), each of which is turned into 8 bits using the character's byte value in ASCII (8 bits × 5 + 24-bit IV = 64-bit WEP key); however, this restricts each byte to be a printable ASCII character, which is only a small fraction of possible byte values ...
Label Distribution Protocol (LDP) is a protocol in which routers capable of Multiprotocol Label Switching (MPLS) exchange label mapping information. Two routers with an established session are called LDP peers and the exchange of information is bi-directional.
If the wrong PIN is entered more than three times, the SIM card will become locked. It can be unlocked by entering the PUK code provided by the mobile service provider, [1] which may be available on the SIM card's packaging, the contract, or provided by customer service after identity verification. After the PUK code is entered, the PIN must be ...
Hitron Technologies (Chinese: 仲琦科技; pinyin: Zhòngqí Kējì) is a Taiwanese company founded in 1986 as a telecommunication equipment supplier [1] [2] and headquartered in Hsinchu City, Taiwan.
An individual’s PIN is the four-digit code they set after opening a debit account with their bank of choice. It is used as a layer of authentication when they perform an electronic transaction ...
However, if the packet is forwarded further, the Router Alert Label should be pushed back onto the label stack before forwarding. The use of this label is analogous to the use of the "Router Alert" option in IPv4 packets. Since this label cannot occur at the bottom of the stack, it is not associated with a particular network-layer protocol.
Penultimate hop popping (PHP) is specified in RFC 3031 Section 3.16 and is a function performed by certain routers in an MPLS enabled network.It refers to the process whereby the outermost label of an MPLS tagged packet is removed by a label switch router (LSR) before the packet is passed to an adjacent label edge router (LER).
