VAMPIRE	eBACS: ECRYPT Benchmarking of Cryptographic Systems	ECRYPT II

Measurements of public-key Diffie–Hellman secret-sharing systems on one machine: amd64; Silvermont (406c4); 2016 Intel Atom x5-Z8350; 4 x 1440MHz; cherry, supercop-20250922

eBATS (ECRYPT Benchmarking of Asymmetric Systems) is a project to measure the performance of public-key systems. This page presents benchmark results collected in eBATS for public-key Diffie–Hellman secret-sharing systems:

• Time (cycles) to generate a key pair: a secret key and a corresponding public key.
• Time to compute a shared secret, given one user's secret key and another user's public key.
• Space (bytes) for a secret key.
• Space for a public key.
• Space for a shared secret.

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 Diffie–Hellman system and each implementation. Designers and implementors interested in submitting new Diffie–Hellman systems and new implementations of existing systems should read the call for submissions.
