VAMPIRE	eBACS: ECRYPT Benchmarking of Cryptographic Systems	ECRYPT II

Measurements of stream ciphers on one machine: amd64; Haswell+AES (306c3); 2013 Intel Core i7-4770; 4 x 3400MHz; speed2supercop, supercop-20260330

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 (or StQ1 starting with supercop-20260214), the median of many speed measurements (or StQ2 starting with supercop-20260214), the third quartile of many speed measurements (or StQ3 starting with supercop-20260214), and the name of the primitive. Measurements with large interquartile range (or stabilized interquartile range) 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.
