Full Form: Binary Bent Lifted Sequence
For more information of "Binary Bent Lifted Sequence", see the section below.
Properties of BBLS Sequences
- Good autocorrelation properties: BBLS sequences have a low peak sidelobe level in their autocorrelation function. This means that they have a low probability of interfering with themselves.
- Low cross-correlation properties: BBLS sequences have a low cross-correlation with other BBLS sequences. This means that they can be used in multiple-access communications systems without causing interference.
- High degree of randomness: BBLS sequences appear to be random, even to sophisticated statistical tests. This makes them ideal for use in applications where security is important.
Applications of BBLS Sequences
BBLS sequences are used in a wide variety of applications, including:
- Spread spectrum communications: BBLS sequences are used to spread the bandwidth of a signal, which makes it more resistant to jamming and interference.
- Radar: BBLS sequences are used to generate radar waveforms that have a high degree of randomness. This makes it difficult for targets to detect the radar.
- Sonar: BBLS sequences are used to generate sonar waveforms that have a high degree of randomness. This makes it difficult for targets to detect the sonar.
Essential Questions and Answers on Binary Bent Lifted Sequence in "MISCELLANEOUS»UNFILED"
What is Binary Bent Lifted Sequence (BBLS)?
BBLS, short for Binary Bent Lifted Sequence, is a type of binary sequence with excellent cryptographic properties. It is constructed by lifting a bent function to a higher dimension, resulting in a sequence with high nonlinearity, balance, and resilience against attacks.
What are the advantages of using BBLS?
BBLS offers several advantages for cryptographic applications:
- High nonlinearity: BBLS exhibits high nonlinearity, making it difficult to predict the output sequence based on previous values.
- Balance: The distribution of 0s and 1s in a BBLS is close to 50%, which provides better statistical properties for cryptographic protocols.
- Resilience: BBLS has good resilience against various cryptanalytic attacks, including linear and differential cryptanalysis.
How is BBLS constructed?
BBLS is typically constructed using the following steps:
- Define a bent function in a lower dimension.
- Lift the bent function to a higher dimension using a lifting operation.
- Apply a permutation to the lifted function to obtain the BBLS.
Where is BBLS used?
BBLS has potential applications in various cryptographic contexts, including:
- Stream ciphers and pseudorandom number generators
- Hash functions and message authentication codes
- Error-correcting codes and data integrity verification
What are the limitations of BBLS?
While BBLS possesses many desirable cryptographic properties, it also has some limitations:
- Computational complexity: Generating BBLS can be computationally expensive, especially for longer sequences.
- Correlation: BBLS sequences may exhibit some correlation between adjacent bits, which can potentially weaken their security.
