MAME: A Compression Function with Reduced Hardware Requirements
نویسندگان
چکیده
This paper describes a new compression function, MAME designed for hardware-oriented hash functions which can be used in applications reduced hardware requirements. MAME takes a 256-bit message block and a 256-bit chaining variable as input and produces a 256-bit output. Seen in the light of attacks on MD5 and SHA-1, our design strategy enables us to evaluate the security of MAME against known attacks. Our design considers the security of side channel attacks against HMAC constructions employing MAME. The main use of logical operations in the design allows us to achieve a hardware implementation of MAME requiring 8.1 Kgates on 0.18 μm technology.

Lossless Microarray Image Compression by Hardware Array Compactor
Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...
متن کاملMagnetite Biomineralization in Magnetospirillum magneticum Is Regulated by a Switch-like Behavior in the HtrA Protease MamE.
Magnetotactic bacteria are aquatic organisms that produce subcellular magnetic particles in order to orient in the earth's geomagnetic field. MamE, a predicted HtrA protease required to produce magnetite crystals in the magnetotactic bacterium Magnetospirillum magneticum AMB-1, was recently shown to promote the proteolytic processing of itself and two other biomineralization factors in vivo Her...

In the RESUME project we explore the use of reconfigurable hardware for the design of portable multimedia systems by developing a hardware friendly scalable wavelet-based video codec. Our scalable video codec provides the ability to decode a video stream with reduced frame rate, resolution or image quality directly from the original encoded or trimmed video stream. This is important for portabl...
متن کاملOn-board optical image compression for future high resolution remote sensing systems
Future high resolution instruments planned by CNES to succeed SPOT5 will lead to higher bit rates because of the increase in both resolution and number of bits per pixel, not compensated by the reduced swath. Data compression is then needed, with compression ratio goals higher than the 2.81 SPOT5 value obtained with a JPEG like algorithm. Compression ratio should rise typically to 4-6 values, w...
