Evaluation of HF ALE Linking Protection
نویسندگان
چکیده
The resurgence of interest in high frequency (HF) radio may be largely attributed to the success of automation in making HF usable by operators with minimal HF training. Unfortunately, Automatic Link Establishment (ALE) technology opens automated HF networks to possible hostile manipulation. To counter this vulnerability, a scheme called Linking Protection (LP) has been developed and standardized that scrambles ALE transmissions so that only legitimate users can interact with protected radios. In this paper, we summarize the LP scheme, and present an evaluation of the impact of LP on linking performance. The evaluation includes both simulation results and measurements of early implementations.

Analysis of Third-Generation HF ALE Technologies
Third-generation HF Automatic Link Establishment (ALE) achieves order-of-magnitude improvements over second-generation ALE in linking speed, network size, and traffic capacity. In this paper we examine the individual contributions to this performance by several of the techniques standardized in the third generation, including synchronous operation, dwell groups, and separate calling and traffic...
متن کاملCompetition between Al2O3 atomic layer etching and AlF3 atomic layer deposition using sequential exposures of trimethylaluminum and hydrogen fluoride.
The thermal atomic layer etching (ALE) of Al2O3 can be performed using sequential and self-limiting reactions with trimethylaluminum (TMA) and hydrogen fluoride (HF) as the reactants. The atomic layer deposition (ALD) of AlF3 can also be accomplished using the same reactants. This paper examined the competition between Al2O3 ALE and AlF3 ALD using in situ Fourier transform infrared (FTIR) vibra...

متن کاملSynthesis of a novel radical trapping and carbonyl group trapping anti-AGE agent: a pyridoxamine analogue for inhibiting advanced glycation (AGE) and lipoxidation (ALE) end products.
[structure: see text] Pyridoxamine is known to be an effective inhibitor of both advanced glycation (AGE) and advanced lipoxidation (ALE) end products. The synthesis of a novel multifunctional AGE and ALE inhibitor, 6-dimethylaminopyridoxamine (dmaPM, 11) is described. The 6-dimethylamino substituent increases the radical trapping ability of pyridoxamine's phenolic group. Results obtained durin...
