VAMPIRE	eBACS: ECRYPT Benchmarking of Cryptographic Systems	ECRYPT II

Measurements of stream ciphers on one machine: amd64; Bonnell (106ca); 2010 Intel Atom N455; 1 x 1000MHz; h2atom, supercop-20240107

eBASC (ECRYPT Benchmarking of Stream Ciphers) is a project to measure the performance of stream ciphers. This page presents benchmark results collected in eBASC:

• Speed (cycles/byte) of encrypting an 8-byte message.
• Speed of encrypting a 64-byte message.
• Speed of encrypting a 576-byte message.
• Speed of encrypting a 1536-byte message.
• Speed of encrypting a 4096-byte message.
• Speed of encrypting a long message. This is computed as 1/3072 of the difference in cycle counts between encrypting 4096-byte messages and encrypting 1024-byte messages.

Graphs show timings for all message lengths between 0 and 4096 bytes. The stair-step shape of a typical curve on the graphs reflects the fact that these stream ciphers handle messages in blocks, such as 64-byte blocks.

Each table row lists the first quartile of many speed measurements, the median of many speed measurements, the third quartile of many speed measurements, and the name of the primitive. Measurements with large variance are indicated in red with question marks. The symbol T: (starting with supercop-20200816) means that the SUPERCOP database at the time of benchmarking did not list constant time as a goal for this implementation. The symbol T!!! means that constant time was listed as a goal for this implementation, but that the implementation failed TIMECOP. (TIMECOP failures are not necessarily security issues; they can sometimes be resolved by, e.g., declaring that a rejection-sampling condition is safe to declassify.)

There is a separate page with more information about each stream cipher and each implementation. Designers and implementors interested in submitting new stream ciphers and new implementations should read the call for submissions.
