CRYPTREC Advisory Committee Held


On May 16, 2001, MPHPT and the Ministry of Economy, Trade and Industry (METI) jointly held the "CRYPTREC (Cryptography Research and Evaluation Committee) Advisory Committee," in order to promote information security measures through widespread use of cryptography.
The studies will continue until the end of March 2002.

1. Purpose

The "e-Japan Priority Policy Program" (decided upon by the Strategic Headquarters for the Promotion of Advanced Information and Telecommunications Network Society: IT Strategic Headquarters on March 29, 2001), based on the Basic Law on the Formation of an Advanced Information and Telecommunications Network Society, stipulates that the government shall implement a range of measures for minimizing service suspensions caused by threats over advanced information and telecommunications networks, so that Japan's security and reliability of advanced information and telecommunications networks can befit the world's leading IT nation.
In particular, objective assessment and standardization of cryptography as a key infrastructure will become essential to ensuring security and reliability of advanced information and telecommunications networks along with the widespread use of authentication such as electronic signatures and the formation of the e-government. To this end, MPHPT and METI held the committee for assessment, etc. consisting of cryptography experts, with the aim of employing the study results into the policy measures of both ministries.

2. Items to be studied

1) Assessment and evaluation of cryptography to be used in accordance with the Law Concerning Electronic Signatures and Certification Services (advice for cryptography for electronic signatures, etc.)
2) Assessment and evaluation of cryptography to be used in the government (advice for cryptography for Government Public Key Infrastructure (GPKI), etc.)
3) Assessment and evaluation of cryptography concerning international standardization (support for standardization activities carried out at international standardization organizations, including ISO, ITU, etc.)
4) Other issues concerning assessment and evaluation of cryptography (study on guidelines for use of cryptography)

CRYPTREC advisory committee keeps cooperative works with CRYPTREC executive committee that is held by Telecommunications Advancement Organization of Japan (TAO) and Information-technology Promotion Agency, Japan (IPA).
TAO and IPA plan to invite cryptographies for assessment and evaluation.



Conformity of Existing Mobile Telephone Terminals with Radio-Radiation Protection Guidelines Confirmed


On June 1, 2001, MPHPT promulgated a ministerial ordinance to amend relevant ministerial ordinances, in order to introduce the Radio-Radiation Protection Regulation*1 to existing mobile telephone terminals operating in close proximity to the side portion of the human head.
Upon introduction of this regulation, MPHPT commissioned the Telecom Engineering Center (TELEC) to conduct conformance confirmation tests of 76 mobile telephone terminals, which are currently sold on the market. In these conformance confirmation tests, all the terminals were proven to be in conformance with the Radio-Radiation Protection Guidelines through measurement of the Specific Absorption Rate (SAR)*2.

Outline of the conformance confirmation tests

1. Purpose
To grasp real SAR data of existing mobile telephone terminals

2. Object terminals
76 mobile telephone terminals (as of the end of January 2001)

3. Measurement method
To measure SAR data of mobile telephone terminals purchased on the market, based upon the "Measurement method of SAR from mobile phone terminals and other terminals that are intended for use in close proximity to the side of the head" (Partial Report of the Telecommunications Technology Council in 2000). Each terminal was measured in eight positional conditions (combination of i) antenna extended/retracted, ii) cheek position/tilted position, iii) left-side/right-side of the phantom*3).

4. Results
It is confirmed that the results of measured SAR data of 76 terminals satisfied the SAR data of 2.0 W/kg under the Radio-Radiation Protection Guidelines. The tests are conducted based upon the Partial Report of the Telecommunications Technology Council in 2000. However, the shape of phantom used this time is slightly different from the shape that is stipulated in the Partial Report. Because the terminals tested are one single unit per each type distributed on the market, in general this may cause deviations in SAR data due to deviations derived from the production process of each terminal. Accordingly, the test results do not necessarily determine the SAR data of said terminals.

[Analysis of the test results]

  1. In comparison of 800MHz- and 1.5GHz-band mobile terminals, the SAR data for 1.5GHz band mobile terminals tend to be higher than that of 800MHz. It is inferred that because 1.5GHz-band radio waves do not penetrate human bodies that deeply but concentrate surface thereon accordingly the maximum SAR data are measured on the surface of human body (phantom) in line with the measurement method this time under which the maximum SAR data are tested.
  2. In comparison of the cheek position and the tilted position, as regards the SAR data for 1.5GHz-band mobile terminals, the tilted position, which means antennas are closer to the head of the phantom, tends to be higher than that of the cheek position. It is shown that the SAR data are greatly decreased by moving the terminal's antenna away from the temporal part.
  3. For both 800MHz- and 1.5GHz-band mobile terminals, the SAR data in the any positional conditions with the antenna retracted tend to be higher than those in the any positional conditions with the antenna extended.
Notes: 1. Radio-Radiation Protection Regulation: The SAR at the side of the head shall be limit (2W/kg) from radio facilities of "land mobile stations conducting mobile radio communications" and "mobile earth stations, which conduct mobile satellite communications through relaying with an artificial satellite station established on a non-geostationary satellite." However, radio facilities with an average antenna power of 20mW or less and radio facilities to which application of the provision under the regulation is thought to be irrational are excluded.
2. Specific Absorption Rate (SAR): The energy flow absorbed by the unit mass of the human tissue exposed to an electromagnetic field. In this case, it is the SAR data averaged over any ten gram of tissue in 6 minutes (average time.) The SAR is expressed in units of W/kg.
3. Phantom: An anthropomorphic model of the human body used to estimate SAR on an experimental basis. This measurement employs a phantom consisting of a shell (container) that represents the shape of the human body and a homogeneous liquid material that fills the shell.

Fig. 1 Distribution of SAR data for 800MHz-band mobile terminals (average value: 0.656 W/kg, standard deviation: 0.217) Fig. 2 Distribution of SAR data for 1.5GHz-band mobile terminals (average value: 1.04 W/kg, standard deviation: 0.261)
Note: These figures indicate the maximum SAR data in 800MHz and 1.5GHz bands under the eight positional conditions.
