Spread spectrum technologies use bandwidth more efficiently than narrowband by spreading signals across more frequencies. Direct-sequence spread spectrum (DSSS) encodes each bit as a sequence of chips, allowing higher data rates like 1 Mb/s with DBPSK and 2 Mb/s with DQPSK modulation. Complementary code keying (CCK) encodes blocks of bits as codes, enabling rates up to 11 Mb/s. Orthogonal frequency-division multiplexing (OFDM) uses subcarriers modulated with techniques like BPSK, QPSK, and 16-QAM to achieve rates from 9 Mb/s to 54 Mb/s. However, the wider channels of spread spectrum mean fewer non-overlapping channels are available and interference must be

Spread spectrum technologies
Direct sequence spread spectrum (DSSS) spreads data over a wide frequency band by combining the data with a redundant bit sequence called a chipping code. It can transmit at 1, 2, 5.5, and 11 Mbps using different encoding and modulation schemes. Barker coding maps each data bit to an 11-bit sequence for 1-2 Mbps using DBPSK or DQPSK. Complementary code keying maps groups of data bits to unique 8-bit sequences for 5.5-11 Mbps using DQPSK phase shifts. DSSS occupies a 22 MHz band but can tolerate some interference due to its processing gain from spreading the signal.
Frequency hopping spread spectrum
Frequency hopping spread spectrum (FH-SS) is a type of spread spectrum technique where the available channel bandwidth is divided into a large number of frequency slots arranged continuously. A transmitted signal occupies one or more of the available frequency slots, with the frequencies selected pseudo-randomly based on the output of a pseudo-noise generator. There are two types of FH-SS: slow FH-SS where one or more data bits are transmitted within one hop, and fast FH-SS where one data bit is divided over multiple hops. FH-SS provides advantages like improved interference rejection, code division multiplexing for CDMA, secure communication, and increased capacity and spectral efficiency. It is used in military communication systems, satellite communication,

Presentation on fhss
Frequency hopping spread spectrum (FHSS) works by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. The transmitter hops from one frequency to another, transmitting short bursts of information on each channel in turn. The receiver hops in synch to receive the signals. This makes the signal resistant to interference and jamming as an eavesdropper would need to know the hop sequence to intercept the entire message coherently.

Brief Introduction to Spread spectrum Techniques
There are two main types of spread spectrum multiple access techniques: frequency hopped multiple access (FHMA) and direct sequence multiple access (DSMA). FHMA involves transmitting digital data on different carrier frequencies in a pseudorandom pattern, while DSMA multiplies a message signal by a pseudorandom spreading signal with a much higher chip rate. Code division multiple access (CDMA) is another name for DSMA. Both techniques allow multiple users to transmit simultaneously on the same frequency band.
Spread spectrum
Spread Spectrum multiple access (SSMA) uses signals that have a much greater transmission bandwidth than the minimum required. It uses a pseudorandom number (PN) sequence to convert a narrowband signal into a wideband noise-like signal before transmission. The two main types of SSMA are frequency hopped multiple access (FH) and direct sequence multiple access (DS). SSMA provides advantages like being immune to multipath interference and having robust multiple access capability in a multiple user environment.

Reverse Channel
The document discusses the reverse channel in CDMA networks. The reverse channel carries information from the mobile station to the base station. It uses OQPSK modulation and has a bandwidth of 1.25MHz from 869-894MHz. The reverse channel consists of an access channel for call setup and control information, and a traffic channel to carry voice data at different rates. It discusses the framing of the synchronization and paging channels in IS-95 networks and also covers soft handoff.
Advantages of qpsk
QPSK encodes two bits per symbol, doubling the data rate compared to BPSK while maintaining bandwidth, or maintaining the data rate but halving the bandwidth needed. It uses differential encoding to avoid phase ambiguity issues. One advantage is its use of DQPSK, which does not require a reference signal for the receiver to compare phases of successive symbols and reconstruct the data. However, it is more sensitive to phase variations than BPSK.

The document discusses authentication and encryption for wireless networks. It states that open authentication provides no user authentication while WEP provides weak authentication and encryption. It recommends using a central server and individually authenticating each user for stronger authentication. WPA and WPA2 create a framework for stronger authentication and encryption, and Cisco Centralized Key Management can be added to increase roaming efficiency. Most security features can be configured on the controller and EAP types will be relayed while the controller uses encryption angle to categorize the security type.
Iuwne10 S04 L06
WLAN security can be configured through the Layer 2, Layer 3, and Security menus. 802.1X uses RADIUS server authentication with optional WEP encryption, while WPA/WPA2 supports both RADIUS server-based enterprise and personal pre-shared key modes. Different client devices provide interfaces for selecting security types including 802.1X, WPA, WPA2, and open networks with web-based authentication.
Iuwne10 S04 L04
EAP-TLS uses certificates and PKI for mutual authentication between clients and RADIUS servers, requiring client and server certificates that must be managed. EAP-FAST establishes a secure tunnel using dynamically generated PACs instead of certificates. PEAP provides one-way authentication from server to client using a server certificate, allowing different inner authentication methods like EAP-GTC and EAP-MSCHAPv2 without client certificates. Cisco LEAP authenticates users via a username and password with dynamic WEP keys.
Iuwne10 S04 L05
WPA introduced a pre-standard framework to improve WEP security by allowing for 802.1X authentication and enhancing the encryption protocol. WPA2 was later standardized and implemented the full 802.11i specification, migrating authentication and encryption to be based on 802.1X and the stronger AES protocol. Additional features were introduced to improve security such as per-packet key mixing and centralized key management solutions to facilitate secure roaming.
Iuwne10 S04 L02
The document discusses various wireless LAN security protocols defined in IEEE 802.11 including open authentication, WEP authentication and encryption, and MAC address filtering. It notes that WEP has weaknesses like weak encryption, repeating initialization vectors that can be used to crack keys, and each client and access point must be configured with matching WEP keys. MAC address filtering allows controlling client access per WLAN by checking MAC addresses against a local or RADIUS server database.
Iuwne10 S04 L01
Cisco WCS is a management tool that can be installed on servers to configure and manage wireless LWAPP controllers and access points using SNMP.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
